03AA8578FFA37F6AD256F0D37AA6F859.taxon	discussion	Species in this group exhibit a more or less dense cover of white scales on the lateral carina of pronotum (Fig. 1 C). Their body is slender, the pronotum at most slightly wider than long (W: L ratio generally <1.30). The body of the penis is generally comparatively very long and apodemes very short (but see D. caldarai sp. nov. and D. karooensis sp. nov.). Eight species are recognized in this group, they are predominantly distributed in eastern and southern Africa, but one species extends to the Arabian Peninsula (D. schoedli) and one is found in North Cameroon, Cape Verde archipelago, Burkina Faso and Senegal (D. lindbergi). All species were collected on inflorescences of Mimosa L. and Vachellia Wight & Arn. (Fabaceae), which probably constitutes the host for larvae. This species group is likely more diverse than what is reported below. Several unique female specimens clearly belonging to new species were found in collections, but not described due to the lack of male or DNA grade material.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFA37F6AD256F0D37AA6F859.taxon	discussion	This species group contains only three species, which exhibit a uniformly pale brown integument, a comparatively small body size, equal to or below 2.5 mm, and a lateral carina on the pronotum lacking a dense cover of white scales. The monophyly of this species group is supported by molecular data, at least for the two species D. pallidus and D. prochesi sp. nov. (Fig. 33). Species in this group are restricted to East and southern Africa, they are associated with Ebenaceae and Achariaceae.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFA37F6AD256F0D37AA6F859.taxon	discussion	This species group is defined by the combination of a glabrous lateral carina on the pronotum, the comparatively large body length (generally beyond 3 mm) and the prosternum at least partly dark brown. The protibiae of the males exhibit a distinct internal comb of erect setae and the sex dimorphism for the shape and curvature of the rostrum is marked (note that these features have not been verified in D. nigrovariegatus Hustache, 1936 due to the unavailability of males). Six species are recognized in this group, they are distributed in Central, East and southern Africa. Most species were collected on male inflorescences and in fruits of Phoenix reclinata Jacq. (Arecaceae) and one species develops in flowers of Strelitzia nicolai Regel & Körn. (Strelitziaceae).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFA37F6AD256F0D37AA6F859.taxon	discussion	This is the largest and possibly a non-monophyletic species group in Derelomus. Stable and simple synapomorphies to define it were not identified in the context of this study. The following combination of features should enable to distinguish this clade from the rest of the genus: lateral carina on pronotum glabrous, claw simple, prosternum uniformly pale brown (except in dark specimens of D. chamaeropis), head concolorous or slightly darker than pronotum and stridulatory plate with compact lines of granules, space between granules as wide or narrower than diameter of a granule. Species in this group are generally either longer than 2.5 mm, with dark patterns on the elytra or with costate elytra and never lack these three features combined. The majority of species also exhibits the following features: presence of a post-ocular dark strip, lateral carina on pronotum with distinct notch or tooth near middle of length, pronotum distinctly transverse (W: L ratio at least 1.36) and elytra in males very wide, lens or pearshaped with 5 th interstriae raised (see D. piriformis). This group is widely distributed in the study area and includes twelve species associated with male inflorescences of various palms (Chamaerops L., Cocos L., Phoenix L.; Arecaceae). Many species are found in sympatry, apparently sharing the same host and tissue. Several species concepts show geographic variants possibly corresponding to distinct species that would deserve more investigation.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFA37F6AD256F0D37AA6F859.taxon	discussion	Molecular analyses DNA-grade specimens were obtained for 19 of the 32 known species of Afrotropical and Mediterranean Derelomus. For COI data alone, the lowest interspecific distance was observed between D. caldarai and D. schoedli (7.6 %), while the highest intraspecific distance was observed in D. chamaeropis between the Moroccan and Spanish populations (3.4 %). The species concepts recovered by morphology were consistent with the best-fit ML tree inferred in IQ-TREE from the analysis of the concatenated dataset, where all species represented by several individuals were found to be monophyletic (Fig. 33). The genus Derelomus was recovered monophyletic, with moderate support (SH-aLRT of 83.4 % and uBV of 64 %). Within Derelomus, interspecific relationships were not highly supported (only four nodes out of 18 have both SH-aLRT> 80 % and uBV values> 95 %); however, nodes leading to specimens belonging to multiple specimens of the same species were generally highly supported (nine nodes out of 12 have both SH-aLRT> 80 % and uBV values> 95 %). Molecular species delimitation analyses based on the COI dataset were highly consistent with the morphological concepts of species, as the results of most SD analyses support extant species boundaries (Fig. 34). A potential lumping of species was inferred only once with the ASAP analysis, between D. pallidus and D. prochesi. Potential intraspecific splits were found twice in the bPTP analysis (for D. schoedli and D. trinotatus), once in the PTP (ML) analysis (for D. schoedli) and three times in the GMYCm analysis (for D. fasciatus, D. peglerae and D. prochesi).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFAD7F61D22DF4097A5CFD2D.taxon	diagnosis	Diagnosis Derelomus signatus can be distinguished by the combination of white scales on the lateral carina of the pronotum, the narrow pronotum (W: L ratio: 1.25), two transverse bands or lines of dark spots on the elytra and black club. It is closest to D. abyssinicus, but in the latter species the rostrum is almost straight in lateral view (Fig. 5 B – C) and the elytra only exhibit one transverse dark band (Fig. 5 A).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFAD7F61D22DF4097A5CFD2D.taxon	description	Redescription (♂) MEASUREMENTS. Body length 2.5 mm. COLOR. Body integument pale brown, head and pronotum darker, club black, elytra with two transverse oblique lines of dark spots on even interstriae; vestiture of dorsum made of white setiform scales, forming one row on each interstria, more visible on odd interstriae. HEAD. Rostrum as long as pronotum in lateral view, moderately and regularly downcurved; in dorsal view 3 × as long as wide, integument densely punctate, with 5 carinae, covered with short suberect whitish setae oriented transversally; antennae inserted near apical ¼ of length; head capsule coarsely punctate in dorsal view, with contiguous suberect whitish scales forming two tufts near eyes; eyes convex, exceeding lateral curve of head capsule in dorsal view; antennal funicle with first segment 2 × as long as wide, equal in length to segments 2 – 4 together, 3 – 7 transverse. PRONOTUM. Wider than long (W: L ratio: 1.25), widest near base, 0.77 × as wide there as elytra at humeral angles, lateral carina forming obtuse angle beyond middle of length; sides abruptly converging in apical 1 / 5, apical constriction deep and visible; integument with large circular punctures, space between punctures dull, narrower than or as wide as diameter of punctures; setae recumbent, cover less dense near basal and apical margins and along median line. METATHORAX. Metanepisterna with scarce setiform scales. ELYTRA. Elongate (W: L ratio: 0.62); sides subparallel in basal ⅔, widest near middle of length; humeri raised, with tuft of white setiform scale; apex jointly rounded, notched at apex of suture; striae with punctures narrower than interstriae; odd interstriae raised; scutellar shield rounded, black, glabrous. ABDOMEN. Underside covered with minute recumbent whitish setae, not contiguous. Stridulatory plate with lines of 6 granules, 0.8 × as long as median line from base; central sclerotized area regularly rounded laterally. LEGS. Profemora moderately thickened near middle of length; protibiae with external margin straight, internal slightly bisinuate; claws appendiculate. TERMINALIA. Body of penis elongate (W: L ratio: 0.17); sides straight in dorsal view, widest at base, converging regularly apicad from apical 1 / 5 of length, apex forming a spatula; in lateral view curvature stronger in basal ½ of length, width narrowing regularly from middle of length to apex; apex curved upward; apodemes very short, less than 0.2 × the length of penis body (Fig. 2 D). Sexual dimorphism Females can be distinguished from males by the rostrum which is slightly longer and more downcurved in lateral view (Fig. 2 C), and by their more convex elytra. Variation Scale cover and patterns on the elytra are variable in this species. In some specimens, the vestiture of the pronotum and elytra is very short and hardly visible. The dark apical band on the elytra may consist of a wide transverse band, only interrupted on the suture or only two dots on interstriae 4 and 7. All specimens examined show two transverse bands on each elytron, the one near the middle of the length, sometimes pale ocher, poorly contrasting with the rest of the integument. The condition of the appendiculate claws is seemingly variable in this species, this feature was not used for the diagnosis of this species.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFAD7F61D22DF4097A5CFD2D.taxon	discussion	Remarks Despite intensive searches, we could not locate the type of Derelomus signatus Gyllenhal, 1836. It is absent from Schoenherr’s and Chevrolat’s collections housed at NHRS, while a label bearing this species name at the bottom of the boxes indicates that a specimen used to be located there. We also searched among the material borrowed by the late G. Kuschel from various institutions, without success. In addition, in a preliminary manuscript left by him, G. Kuschel stated that he did not examine the type of this species, suggesting that the specimen was unavailable when he undertook his work on this genus (circa 2007). The original type is therefore considered as lost. In order to stabilise the nomenclature, and given the homogeneity of the D. signatus species group, a neotype is here designated (ICZN art. 75). The original description given by Gyllenhal provides diagnostic features: “ […] rostrum capite dimidio longius, validum, valde arctuatum [rostrum 1.5 × as long as head, stocky and strongly downcurved]. […] Antennae testaceae, clava nigra [antennae reddish brown, club black]. […] sutura interstitiisque alternis paulo elevatioribus, laevibus; […] lineolis nonnullis brevibus, sparsis, brunneis, notata [odd and sutural interstriae slightly raised, smooth; with few scattered brown spots]. ” In southern Africa where this species was described, these features apply only to one Derelomus morphospecies for which one male from Zambia and 16 females from Southern and Eastern Africa are available in the material examined. The male specimen of this series is designed as the neotype for the species name Derelomus signatus Gyllenhal, 1836 [here designated] and was labelled accordingly [deposited at NHMUK]. A redescription of this species is provided to report the diagnostic features with closely related species. Due to misidentifications in reference collections, the specimen included in Haran et al. (2022 b) under the name D. signatus (JHAR 01036) is in fact D. schoedli Rheinheimer, 2005.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFB57F79D222F32A7D8AF9B5.taxon	discussion	Remarks In the collection housed at NHMUK, eight specimens corresponding in all respects to the material listed in the original description of D. abyssinicus (Abyssinia, Doukham, 1926) were located. As no specific specimen was designed in the description as holotype, the male specimen bearing a red type label was designated as the lectotype for this species [here designated] and was rellabeled accordingly. The other specimens from the series were labelled as paralectotypes. This species in its current concept shows a significant degree of variability, with males from Rwanda (Kinazi) and Uganda (Kibalinga area) exhibiting a much shorter rostrum and more robust antennae than the lectotype. In the original description, Hustache also reported a color and size variation in specimens from Mulu compared to those from Duken (Ethiopia). After examination of the series, especially the male genitalia and stridulatory plate, no stable and significant differences were observed and all the specimens are therefore left under the name D. abyssinicus pending further investigation. A single female specimen from Mulu with a very divergent phenotype (different color pattern, rostrum strongly downcurved) was excluded from the paralectotype series and labelled as Derelomus sp. (NHMUK).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFB07F7AD258F3B37F3FFB67.taxon	diagnosis	Diagnosis Derelomus caldarai sp. nov. can be distinguished by the combination of elytra with a single transverse band, the presence of scales on the lateral carina of the pronotum, appendiculate claws and a comparatively short penis with a broadly rounded apex not forming a spatula (Fig. 6 D). This species is closely related to D. schoedli, but in the latter species, the apex of the penis forms a distinct spatula, strongly bisinuate in lateral view (Fig. 9 D). The two species show a genetic distance of 7.6 % for the standard barcode fragment (South African versus Ethiopian specimens, JHAR 05867 and JHAR 01036 respectively). No robust feature enabling separation of the females of the two species was identified in the course of this study.

03AA8578FFBE7F71D22EF7B47AC1F8EB.taxon	discussion	Remarks Derelomus pericarti was described based on a series of male and female specimens without designation of a holotype (Hoffmann 1968). In the J. Péricart and A. Hoffmann collections housed at MNHN, the series of specimens from N’Djamena, Farcha, used for description (species identification handwritten by Hoffmann) was located. These specimens bear red types and paratype labels. A male specimen bearing the red type label is designated as the lectotype for Derelomus pericarti [here designated] and was labelled accordingly. The rest of the series was labelled as paralectotypes for this species.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFB97F4DD23DF4097F89FBAC.taxon	discussion	Remarks Only two males are available in this species, from Saudi Arabia and Ethiopia. They show slight differences in rostrum shape and size (slightly longer and more downcurved in the Ethiopian specimen) and the examination of longer series will probably increase our knowledge on the variability of morphological features reported here in the redescription. The rest of known specimens are females (Rheinheimer 2005). Female specimens cannot at this stage be distinguished from those of D. caldarai sp. nov. based on morphological features. The list of material corresponds to that reported in Rheinheimer (2005) and females from a series in which a male was available for verification (Ethiopia). Other material from Botswana, Kenya, Rwanda, Republic of South Africa and Zambia (housed at CMNC, DEI, MNHN, NHMUK, RMCA, TMSA and USNM) was provisionally labelled as Derelomus “ schoedli / caldarai ”, see below.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FF847F48D255F09E7A26FDA0.taxon	diagnosis	Diagnosis Derelomus pallidus can be distinguished in the combination of small body size (up to 2.5 mm), a short rostrum (at most as long as the pronotum in lateral view; Fig. 10 B), the uniformly pale brown body integument (the darker triangular area as base of the elytra in this species is due to the dark color of the tergites partly masked by the wings in repose condition, some specimens have the head and rostrum slightly darker) and the simple claws. It can be distinguished from other species in the D. pallidus group by its comparatively short rostrum (Figs 10 B, 11 B – F). The general appearance of this species is close to another one in Derelomini: Ebenacobius rectirostris Haran, 2022, but in the latter, the interocular space bears a groove (absent in Derelomus) and the body of the penis lacks a thickening near the base (synapomorphy in Derelomus). In our current knowledge, D. pallidus is the only species of Derelomus associated with the flowers of Euclea L. (Ebenaceae).

03AA8578FF847F48D255F09E7A26FDA0.taxon	biology_ecology	Life history Adults of this species are found in prodigious numbers on inflorescences in anthesis of Euclea racemosa (Ebenaceae), which likely constitutes its host plant. They accidentally visit the flowers of other plants and were sporadically recorded on Fabaceae and Anacardiaceae. A specimen was also intercepted in the port of Los Angeles (USA) on imported Phylica L. sp. (Rhamnaceae) in 2002 (USNM). The records on flowers of Diospyros L. species would deserve further observations in order to verify if this species can develop on Ebenaceae out of Euclea. Derelomus pallidus was found in sympatry with Ebenacobius san Haran, 2022 on Euclea racemosa and with Ebenacobius hessei Haran, 2022 on an unidentified Euclea (Haran et al. 2022 b). Note that multi species assemblage of weevils on white and pendulous inflorescences of dioecious plants like Euclea agree with the typical patterns of brood-site pollination mutualism (Haran et al. 2023 a). Adults were recorded from January to March in East Africa (Kenya) and almost all year round in southern Africa (Angola and Republic of South Africa, not recorded in January, May and October – November).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FF847F48D255F09E7A26FDA0.taxon	discussion	Remarks In the Fåhraeus collection housed at NHRS, a female specimen under the name Derelomus pallidus and fitted with the labels “ Cap. b.; sp. [cape of good hope] ” and “ Drége ” (as reported in the original description) was located. This specimen is the lectotype [here designated] for Derelomus pallidus Fåhraeus, 1844 and was labelled accordingly. In the Faust-Hartmann collection housed at MTD, a syntypic series of specimens (1 ♂, 4 ♀♀) under the name Derelomus pallidus and bearing the labels “ Usambara ” and “ Kraatz ” as reported in the original description was located. The male specimen of this series was designated as the lectotype for Derelomus pallidus Hartmann, 1904 [here designated] and was labelled accordingly. The name Derelomus pallidus Hartmann, 1904 was replaced by Derelomus hartmanni Klima, 1934 in the Catalogus Coleopterorum (Klima 1934), the former combination being preoccupied by Derelomus pallidus Fåhraeus, 1844. Detailed examinations of external and internal morphology of the type material of Derelomus pallidus Fåhraeus, 1844 and Derelomus hartmanni Klima, 1934 as well as specimens related to these species from various localities showed no significant differences. The rostrums in the lectotype and the paralectotypes of D. hartmanni are slightly longer and more downcurved than in the lectotype of D. pallidus, but the examination of long series of specimens of D. pallidus shows that the shape of the rostrum is quite variable at population level, a feature not associated with genetic differences (specimens included in Haran et al. 2022 a were variable for that feature). In addition, the host plant of D. pallidus (Euclea racemosa L.) is widely distributed in austral and eastern Africa, and occurs where D. hartmanni was recorded (Tanzania). As a result of this, the names Derelomus pallidus Hartmann, 1904 and Derelomus hartmanni Klima, 1934 are proposed as junior synonyms of Derelomus pallidus Fåhraeus, 1844 [new synonymies].	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FF837F44D25AF3797DA2FB1B.taxon	biology_ecology	Life history Derelomus prochesi sp. nov. was collected in almost all localities on flowers of the tree Kiggelaria africana (Achariaceae), which probably constitutes its host plant. This species forms a supported phylogenetic clade with Derelomus pallidus (Fig. 33) associated with Euclea racemosa (Ebenaceae). Such clade exhibits a derived condition of development on dicot plants from an ancestral association with palms (Arecaceae) in the genus Derelomus. The flowers of Euclea spp. and Kiggelaria africana show remarkable morphological similarities, possibly arising from convergently selected features to host weevils. More generally, Kiggelaria trees agree in several aspects with the trends of brood-site pollination mutualism with weevils (dioecy, patchy distribution, cantharophilous flowers; Haran et al. 2023 a). Such an interaction would deserve detailed investigations. Adults were collected from July to October.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FF8D7F40D250F37A7D92FCB8.taxon	biology_ecology	Life history This species develops on Strelitzia nicolai (Strelitziaceae), the larvae mine the floral peduncle. Adults stand hidden at the base and between the white petaloid sepals during the day. There is no indication that this species can develop from other species of the genus (SP obs.). Strelitzia nicolai flowers show a structure and a production of nectar typical of ornithophily and sunbirds (Passeriformes, Nectariniidae) were identified as the main flower visitors and pollinators of this species (Frost & Frost 1981). Given the pollination activity in Derelomus and the general trend of phylogenetic conservatism of this behaviour at genus level (Haran et al. 2023 a), the implication of this species as a co-pollinator would deserve investigations. Adults were collected from June to December.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FF8D7F40D250F37A7D92FCB8.taxon	distribution	Distribution Derelomus strelitziae sp. nov. follows the distribution range of its host along the southern coast of the Republic of South Africa (Eastern Cape, KwaZulu-Natal & Western Cape provinces). Because the host plant of this species is naturally widespread, abundant, and commonly cultivated – and flowers throughout the year – it provided an ideal opportunity to assess the species’ occupancy. During a dedicated field trip between May and August 2010, we surveyed as many inflorescences as possible at each location where the host plant, Strelitzia nicolai, was present across the genus’ distribution range (Fig. 12 G). Most S. nicolai specimens sampled were from natural populations, except in Plettenberg Bay and Barberton near Mbombela, where cultivated plants were included. The target species was found in all but one locality, with a frequency of occurrence ranging from 2 % to 33 % of flowers sampled. Its presence in areas where S. nicolai is not native indicates that D. strelitziae has expanded its range alongside its host. Flowers of Strelitzia caudata R. A. Dyer and S. alba (L. f.) Skeels could not be sampled during this study.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FF947F5CD25BF4B37C22F85A.taxon	diagnosis	Diagnosis This species belongs to the D. nigrovariegatus group, characterised by the combination of a glabrous lateral carina on the pronotum, the large body length (generally beyond 3 mm) and the prosternum at least partly dark brown. Within this species group, it can be distinguished by the contrasting transverse dark band on the elytra and the prosternum with dark spots on the pale brown integument. The narrow space between the granules of the stridulatory plate seems diagnostic for this species (although this feature has not been examined for D. nigrovariegatus).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FF997F53D229F44D7C28F81E.taxon	biology_ecology	Life history This species was found on inflorescences and infructescences of Searsia glauca and an unidentified Searsia (Anacardiaceae) in the Western Cape Province of the Republic of South Africa. Searsia in anthesis tends to attract a lot of insects, including weevils, not always associated with this bush at larval stages. However, several observations suggest that this species is restricted to Searsia: it was collected during daytime and at night on this plant only, at several sites and never recorded on flowers of the surrounding vegetation despite intensive search. Also, the specimens collected in Gansbaai consisted of ill-sclerotized and thus recently emerged individuals likely performing a maturation feeding on their host.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FF997F53D229F44D7C28F81E.taxon	discussion	Remarks In the Faust-Hartmann collection housed at MTD, a syntypic series of four female specimens under the name Derelomus fasciatus and bearing the labels “ Usambara ” and “ Kraatz ” as reported in the original description was located. One of the specimens of this series was designated as the lectotype for Derelomus fasciatus Hartmann, 1904 [here designated] and was labelled accordingly. Derelomus fasciatus as treated here may be a complex of closely related species or lineages in process of speciation. The Tanzanian and South African populations show slight differences (based on the very few specimens available); in the latter, the rostrum is slightly shorter and less downcurved, the pronotum is more convex laterally and the antennal club is pale brown. Also, a single female from South Africa (JHAR 01252) exhibits a contrasting body and rostrum shape with specimens of the same series. This specimen likely corresponds to a distinct species.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

Its host is widely distributed in continental Africa.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFE47F2ED228F44B7FD2FA4C.taxon	discussion	Remarks In the collection housed at NHRS, a male and a female specimen under the name Derelomus languidus “ Schr. Fhr ” and bearing a label of the type locality [Cape of Good Hope] were located. The male specimen of this syntypic series (fitted with a red type label) is designated as the lectotype for Derelomus languidus Fåhraeus, 1844 [here designated] and was labelled accordingly. The examination of the series of Derelomus rectirostris Hustache, 1937 (Democratic Republic of Congo) revealed no significant morphological difference with the series of Derelomus languidus Fåhraeus, 1844 from the Republic of South Africa. The specimens from the Democratic Republic of Congo are slightly smaller (about 3 mm long versus 4 in D. languidus from the Republic of South Africa), the antennae are inserted slightly beyond the apical ⅓ of the length and the pronotum is less transverse. However, these variations are common between populations from central-eastern and southern Africa in Derelomus and the examination of the internal structures revealed no significant differences between the two series. As a result, the species name Derelomus rectirostris Hustache, 1937 is proposed as a junior synonym [new synonymy] of Derelomus languidus Fåhraeus, 1844. This species shows some affinities with the D. nigrovariegatus group (large size, arrangement of granules on the stridulatory plate and development on inflorescences of P. reclinata) but it is kept in a distinct group here due to the peculiar shape of the body of the penis, the size of the apodemes, the absence of a comb of seta on the protibiae of the males and the prosternum uniformly pale brown.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFE37F24D25CF4097C60F874.taxon	diagnosis	Diagnosis This species shows a typical elytral pattern, generally forming two dark spots on the suture, one at the base and a second beyond the middle of thelength. In the D. ephippiger group, it can be distinguished by its very long rostrum, about 7 × as long as wide in dorsal view in the male (only 5 × in D. peglerae sp. nov.) and its stridulatory plate with bisinuate lines of the granules (Fig. 22 E). The specimens lacking dark spots on the elytra resemble D. piriformis, but in the latter species, the rostrum of the male is much shorter (4.5 – 5 × as long as wide) and the male’s protibiae bear an internal comb of elongate setae (absent in D. antonioui).

03AA8578FFE37F24D25CF4097C60F874.taxon	description	Redescription (♂) MEASUREMENTS. Body length 3.0 – 4.0 mm. COLOR. Body integument uniformly pale brown to brown, generally with post-ocular dark strip and two dark spots on elytral suture, one at base and one beyond middle of length of interstriae 1 – 4; rostrum generally darker apicad; elytra and pronotum with minute recumbent whitish setae, glabrous in appearance. HEAD. Rostrum distinctly longer than pronotum in lateral view (1.2 ×), slightly and regularly downcurved; in dorsal view about 7 × as long as wide, integument densely punctate, forming 5 longitudinal carinae; antennae inserted near apical ¼ of length; head capsule densely punctate in dorsal view, forehead flat or slightly concave; eyes convex, exceeding lateral curve of head capsule in dorsal view; antennal funicle with first segment 2.5 × as long as wide, equal in length to segments 2 – 3 together, 2 – 7 isodiametric. PRONOTUM. Wider than long (W: L ratio: 1.37 – 1.5), widest near base, almost as wide there as elytra at humeral angles, side slightly rounded, converging apicad, forming notch or blunt tooth near middle of length; apical constriction deep or superficial; integument with punctures rounded, space between punctures smooth, shiny, micropunctate, wider than diameter of punctures in middle, narrower laterally. METATHORAX. Metanepisterna with recumbent white setae, non-contiguous. ELYTRA. Longer than wide (W: L ratio: 0.73); sides slightly convex, widest near middle of length; humeri raised; apex rounded, notched at level of suture; striae with punctures about ¼ as wide as width of interstriae; interstriae flat or slightly convex, 5 raised into carina; scutellar shield rounded, pale brown or dark brown, coated with small recumbent scales. ABDOMEN. Underside uniformly pale brown, with minute recumbent whitish setae, not contiguous. Stridulatory plate with lines of 12 granules ¾ × as long as median line from base, bisinuate. Central sclerotized area narrow, distinctly longer than wide, rounded at base (Fig. 22 E). LEGS. Profemora moderately thickened near middle of length; protibiae with external margin straight, internal bisinuate, setae on apical half of internal margin recumbent, at most as long as claws; claws simple. TERMINALIA. Body of penis elongate (W: L ratio: 0.18), 3.5 × as long as apodemes; sides subparallel in dorsal view, narrowing in apical ⅓, apex acuminate; in lateral view curvature stronger in basal ⅓ of length, width narrowing regularly from apical ⅓, apex bisinuate (Fig. 22 D). Sexual dimorphism Females can be distinguished from males by the rostrum, which is slightly narrower in dorsal view, with the integument shinier and more downcurved in lateral view (Fig. 22 C). The antennae are inserted at the apical 2 / 5 of the rostrum (¼ in males; see Alziar 2007).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFE37F24D25CF4097C60F874.taxon	biology_ecology	Life history Adults were collected in high numbers on male inflorescences of Phoenix canariensis (Arecaceae), a species native to Canary Island introduced to Cyprus, but there is no direct evidence that this weevil uses this palm as host for larval development. Other specimens were found on Phoenix dactylifera L., also without details on larval development. Alziar (2007) suggested that P. dactylifera could be the ancestral host of D. antonioui that subsequently shifted on P. canariensis once introduced to Cyprus. The record of this species in Saudi Arabia, where P. dactylifera is widespread, agrees with this hypothesis. Note that a palm endemic to the eastern Mediterranean region (Greece and Turkey), Phoenix theophrasti Greuter, also occurs near Cyprus with no record of associated Derelomus species yet. Adults of D. antonioui were recorded from January to May.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFEE7F26D228F4097AEEF81B.taxon	diagnosis	Diagnosis In the D. ephippiger group, this species can be distinguished by its typical elytral pattern, forming a large and contrasting dark spot beyond the middle of the length on each elytron, sometimes merged in a transverse strip and by the body of the penis which is very elongate with the sides concave. This species looks similar to D. chamaeropis, but in the latter species, the elytra are always uniformly pale brown without pattern.

03AA8578FFE97F3FD20CF4097CEDF873.taxon	diagnosis	Diagnosis This species can be distinguished from others of the D. ephippiger group by the combination of the pronotum almost as wide as the elytra near the middle of the length and the elytra comparatively elongate (W: L ratio: 0.68 – 0.77), lacking a contrasting dark pattern and with interstriae 9 flat in females, not enlarged in males. This species is closely related and sometimes sympatric with D. piriformis, but in the latter species, males have very convex elytra and a comb of setae on the protibiae (side of elytra only slightly convex and protibiae lacking comb in D. chamaeropis) and the females have a longer and narrower rostrum (Fig. 25 B – D).

03AA8578FFE97F3FD20CF4097CEDF873.taxon	description	Redescription (♂) MEASUREMENTS. Body length 2.5 – 3.7 mm. COLOR. Body integument pale brown, scutellar shield, pronotum and head including rostrum generally darker, in some individuals interstriae 1, sometimes 2 darker as well; elytra and pronotum with minute recumbent whitish setae, glabrous in appearance. HEAD. Rostrum slightly longer than pronotum in lateral view (1.1 – 1.15 ×), regularly downcurved; in dorsal view 4 to 5.5 × as long as wide, integument densely punctate, forming 5 longitudinal carinae; antennae inserted near apical ¼ of length in lateral view; head capsule densely and coarsely punctate in dorsal view, forehead flat or slightly concave; eyes convex, exceeding lateral curve of head capsule in dorsal view; antennal funicle with first segment 2 – 2.2 × as long as wide, slightly longer than segments 2 – 3 together, 2 longer than wide, 3 – 7 transverse. PRONOTUM. Wider than long (W: L ratio: 1.34 – 1.45), widest at basal ⅓ of length, 0.95 – 1 × as wide there as elytra at humeral angles, sides slightly convex, converging regularly from basal ⅓ to apex, lateral carina forming notch near middle of length; apical constriction distinct, about as deep as width of scape in middle of length; integument with punctures rounded, space between punctures dull, micropunctate, wider or narrower than diameter of punctures in middle, narrower anteriorly and laterally. METATHORAX. Metanepisterna with recumbent white setae, non-contiguous. ELYTRA. Longer than wide (W: L ratio: 0.68 – 0.77); sides slightly convex, widest near middle of length; humeri raised; apex jointly rounded or notched at level of suture; striae with punctures about ⅓ – ¼ as wide as width of interstriae; interstriae slightly convex, interstriae 5 sometimes raised in basal ⅔, 9 flat; scutellar shield rounded, coated with few small recumbent scales, not concealing integument. ABDOMEN. Underside with ventrites 1 – 2 darker than 3 – 5, with minute recumbent whitish setae, not contiguous. Stridulatory plate with lines of 10 – 11 granules ⅔ × as long as median line, slightly convex. Central sclerotized area longer than wide, truncate at base (Fig. 24 F). LEGS. Profemora moderately thickened near middle of length; protibiae with external margin straight, internal slightly bisinuate, setae on apical half of internal margin recumbent, at most as long as claws; claws simple. TERMINALIA. Body of penis elongate (W: L ratio: 0.25), about 1.3 × as long as apodemes; sides subparallel in dorsal view, widest in basal ⅔, converging apicad from apical ⅓, apex acuminate; in lateral view curvature stronger in basal ⅓ of length, width narrowing regularly from near ½ of length, apex slightly curved upward (Fig. 24 E). Sexual dimorphism Females can be distinguished from males by the rostrum which is narrower and longer in dorsal view. In lateral view, the rostrum is distinctly longer than the pronotum in females (slightly longer than pronotum in males; Fig. 24 B – D). The antennae are inserted at apical ⅓ in females (¼ in males). Variation This species is quite polymorphic. Morphological variation occurs at two levels. First, D. chamaeropis consists of genetically isolated lineages distributed around the western part of the Mediterranean region (see Remarks section below). These populations show slight morphological divergences. For example, the rostrum of males is on average slightly longer and narrower in populations from Spain (mean W: L ratio: 0.24 (0.21 – 0.25); width measured at antennal insertion) than those from Sicily (mean W: L ratio: 0.18 (0.15 – 0.22 )). Within the eastern clade, rostrum length and width also vary slightly between the French, Italian and Moroccan specimens examined. In addition to these geographic variations, the phenotype of adults in a given population is also variable. Variation includes ‘ major’ males, with a comparatively wide pronotum and 5 th elytral interstriae raised and ‘ minor’ males with a comparatively narrow pronotum and 5 th elytral interstriae flat. Color variation ranges from specimens uniformly pale brown, to specimens with brown elytra and a dark brown pronotum, head and rostrum (Fig. 24 A – D), more rarely with the body (head, pronotum and elytra) uniformly dark brown.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFE97F3FD20CF4097CEDF873.taxon	biology_ecology	Life history Derelomus chamaeropis is the specific brood-site pollinator of the Mediterranean dwarf palm: Chamaerops humilis (Arecaceae; Anstett 1999). Adults fly and reach inflorescences of both male and female plants, attracted by scents emitted by leaves (Dufaÿ et al. 2002), thus transferring pollen to the stigma of female inflorescences. They mate and oviposit in the rachis of the inflorescences (Anstett 1999; Fig. 24 I – K) and larvae develop in the stem of inflorescences, mainly on male plants. Successful larval development has also been described in female plants, but with markedly lower frequency and densities than on male plants (Dufaÿ & Anstett 2004; Jácome-Flores et al. 2018). Adults are active during the flowering season of C. humilis, from March to June. Larval development takes place in the decaying woody tissues of rachises from early summer to late winter. Pupation takes place within the rachises. As for many brood-site pollination systems involving weevils, C. humilis is co-pollinated by the sap beetle Meligethinus pallidulus (Erichson, 1843) also developing on male inflorescences (JH obs.) and visiting females ones (M. Dufaÿ pers. com.). Both species are efficient pollinators, even for isolated populations of palms resprouting after fire (García et al. 2018). The report of D. chamaeropis on P. canariensis (Lepseme 1941) is likely accidental.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFE97F3FD20CF4097CEDF873.taxon	discussion	Remarks In Fabricius’ collection housed at ZMK, a unique female specimen under the identification name “ Curculio (= Rhynchaenus) chamaeropsis F., 1798 ” and fitted with a red type label was located. This specimen is the holotype of Curculio chamaeropis Fabricius, 1798 and was labelled accordingly. In Shoenherr’s collection, housed at NHRS, the holotype of Derelomus chamaeropis var. β Gyllenhal, 1836 was located and labelled accordingly. In the same collection, a male specimen bearing a red type label and corresponding in all aspects to the description of Derelomus subcostatus Boheman, 1844 was located. This specimen is the holotype of Derelomus subcostatus Fåhraeus, 1844 and was labelled accordingly. Based on a detailed examination of these types and a molecular analysis of specimens newly sampled in the region of the type localities, it is stated here that the specimens used to describe Derelomus chamaeropis var. α and β and D. subcostatus all belong to the same species. As a result, the names Derelomus subcostatus Fåhraeus, 1844 and Derelomus chamaeropis var. β Gyllenhal, 1836 are proposed as junior synonyms [new synonymy] of Derelomus chamaeropis (Fabricius, 1798). The elements used to reach this conclusion are detailed hereafter. Derelomus chamaeropis was described on a female from N Morocco. This species is specific to Chamaerops humilis (see Life history section below) and follows the distribution range of this palm in the western Mediterranean region (Caldara et al. 2013). Derelomus subcostatus was described from a male specimen from Sardinia Island (Italy), the specimens related to this species being also associated with C. humilis (Veyret 1940). The limited details in the original descriptions and the substantial intraspecific variation found in D. chamaeropis have resulted in confusions in the interpretation of both species. For some authors, D. subcostatus is a valid species occurring in sympatry with D. chamaeropis (Tempère & Péricart 1989; Caldara et al. 2013) while others treat it as a morphological variant of D. chamaeropis (Hoffmann 1958). In order to clarify this situation, fourteen populations (1 – 4 specimens per population) were sampled across the distribution range of C. humilis (France, mainland and Corsica Island; Italy, Sicily and Pantelleria Island; Morocco and Spain; see detail in Other material section) and sequenced for the standard barcode fragment (see Material and methods section for protocol). This sampling included specimens identified by direct comparison with the holotypes: a female specimen of D. chamaeropis from Morocco (JHAR 03220 - 02) and a male specimen of D. subcostatus from Italy (Sicily; JHAR 04886 - 08). The populations from Spain also included specimens related to the varieties α and β of D. chamaeropis (male with or without costate elytra, with or without dark head and pronotum; Fig. 24 A – C). Derelomus chamaeropis was recovered as a single species for all the species delimitation methods used (Fig. 34), despite intraspecific distances ranking up to 3.4 % between specimens from Morocco (KC 783895) and Spain (JHAR 07851 - 02). Also, the variations observed at population level in the male are not associated with genetic divergences in mitochondrial sequences (Fig. 33). As such, all specimens previously referred to as D. chamaeropis and D. subcostatus are in fact a unique species forming a ring of more or less isolated populations distributed in the western mediterranean area. This phylogeographic pattern is typical of Mediterranean species and results from the isolation of populations in southern European refugia during glacial maxima (Hewitt 2000). This pattern is also in agreement to some extent with the genetic structure of Chamaerops humilis that shows substantial differentiation among populations across its distribution range (De Cauwer et al. 2025). This may suggest that both this palm and its associated pollinator experienced similar fragmentation of distribution range during glacial maxima. At population level, specimens show substantial morphological variation, in particular in males, a condition widely encountered in weevils engaged in brood-site pollination (Haran et al. 2020, 2023 a) and not associated with genetic divergence. The Sardinian specimen used by Boheman to describe Derelomus subcostatus combines the two factors of morphological variability in D. chamaeropis: it is slightly morphologically divergent from populations from Morocco used to describe D. chamaeropis (rostrum comparatively short) and exhibits the costate elytra of a ‘ major’ male, thus showing a substantial apparent divergence with the female holotype of D. chamaeropis. But as detailed above, all these specimens belong to the same species. The species name Ochrinulus antigae Reitter, 1887 was set in synonymy with Derelomus chamaeropis (Fabricius 1798) by Reitter himself (Reitter 1887), the specimen used to describe this species was collected in Barcelona (Spain) [not verified in the context of this study].	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFF77F3AD238F4097AC2FDF8.taxon	diagnosis	Diagnosis In the D. ephippiger group, this species can be distinguished by the combination of a uniformly pale brown integument, and males with the elytra widest beyond the middle of the length, protibiae with an internal comb of elongate setae and a comparatively moderately long rostrum (4.5 – 5 × as long as wide in dorsal view). Females can be distinguished by the distinct narrowing at the base of the rostrum. Derelomus piriformis is closely related and sometimes sympatric with D. chamaeropis, but in the latter species, males have the elytra slightly convex in dorsal view and the protibiae lacking an internal comb (very convex elytra and protibiae with a comb of setae in D. piriformis) and females have a shorter and wider rostrum (Fig. 24 D). Uncorrected p - distances between these species range from 8.0 to 8.8 %.

03AA8578FFF77F3AD238F4097AC2FDF8.taxon	biology_ecology	Life history This species is the specific brood-site pollinator of Phoenix canariensis (Arecaceae), the Canary Island date palm. Adults visit male inflorescences at anthesis stage. Development of larvae and pupae takes place in the enclosed flowers. The development continues on the ground after flower abscission, the declining flower forming a cell protecting the pupa. Each flower hosts only one larva (Piry & Gompel 2002). In this pollination by deceit system, adults carrying pollen and searching for male inflorescences are inadvertently attracted by female inflorescences (producing similar olfactory clues) where they transfer pollen to stigma (Meekijjaroenroj & Anstett 2003). Derelomus piriformis was also recorded on male inflorescences of Chamaerops humilis in the South of France (Veyret 1940, identified as D. subcostatus in the latter paper), but there is no evidence that it can use this palm for larval development. Adult specimens may be found active on its hosts as long as male inflorescences in anthesis are available. This flowering phenology seems to vary across areas of introduction, from late summer to late autumn in the south of France (Piry & Gompel 2002), all year round in Israel (Friedman 2006). Adults are attracted by UV lights (Piry & Gompel 2002).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFF77F3AD238F4097AC2FDF8.taxon	distribution	Distribution This species is native to the Canary Island where Phoenix canariensis originates. This palm is widely traded and planted for ornamental purposes, and D. piriformis has probably been transported simultaneously. It is now widely distributed in the Mediterranean region and Madeira Island (sorted by date of first record): Morocco, 1930 (Hoffmann, 1938); Madeira (Portugal) & France, 1936 (Hoffmann 1938; Veyret, 1940; PW collection); Italy, 1966 (CBGP coll.; Abbazzi & Osella 1992); Israel, 1976 (Friedman 2006); Greece, 1990 (Kakiopoulos et al. 2022); Corsica Island (France), 2015 (CBGP coll.). Further records: Canary Islands and Spanish mainland (Caladara 2013). Introduced to South America (Chile) with its host plant (Elgueta & Marvaldi 2006) and to North America (California).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFF77F3AD238F4097AC2FDF8.taxon	discussion	Remarks In A. Hoffmann’s collection housed at MNHN, three specimens corresponding in all aspects to the material listed in the original description of D. piriformis and bearing a red type label were located. As no specific specimen was designed in the type series, a specimen (Funchal, Madeira) was designated as the lectotype for this species [here designated] and was relabelled accordingly. The two other specimens from the series (Rabat, Morocco) were labelled as paralectotypes. Due to the uncommon sexual dimorphism in this species (males have the elytra more convex than females, a condition rare in weevils), the specimens considered by A. Hoffmann as males are in reality females, and conversely (Piry & Gompel 2002). The sex of specimens reported above corresponds to verified specimens, based on dissection when necessary. In the same collection, a female specimen labelled “ Derelomus kocheri ” by the hand of Hoffmann and bearing a red type label was located. For the reasons described above, this specimen is not a male as reported in the original description but a female one. This specimen is the holotype of Derelomus kocheri Hoffmann, 1957 and was labelled accordingly. Detailed examination of external and internal morphological features of this specimen and comparison with type and non-type material of D. piriformis from various regions revealed no relevant differences. In addition, the type locality of D. kocheri (Rabat, Morocco) is the same as the paralectotype of D. piriformis. As a result of this, the species name Derelomus kocheri Hoffmann, 1957 is proposed as a junior synonym of Derelomus piriformis (Hoffmann, 1938) [new synonymy]. Due to the early introduction of D. piriformis around the Mediterranean Sea and to the unclear taxonomic definition of D. subcostatus Boheman, 1844 (= D. chamaeropis (Fabricius, 1798), see Remarks section under that species), many specimens referred to as D. subcostatus in early collections and publications correspond to D. piriformis in reality. This is relevant to the publication of Veyret (1940).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFF87F32D229F09F7C30FA98.taxon	discussion	Remarks In the collection housed at NHMUK, a male specimen from Makindu labelled “ Derelomus bivirgatus Mshl., Type ♂ ” and bearing a red type label was located. As the description of this species does not refer to a specific type specimen, this male is designated as the lectotype for Derelomus bivirgatus Marshall, 1951 [here designated] and was labelled accordingly. The rest of the specimens were labelled as paralectotypes. Specimens from Kenya and the Republic of South Africa show slight morphological differences, in the latter the rostrum is more downcurved basally in both sexes. These differences are related to regional variation, as observed in other species distributed in Eastern and Southern Africa (D. fasciatus, D. pallidus, etc).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFFB7F0FD257F0947C3FFC51.taxon	discussion	Remarks This species is known from very few specimens, it is seemingly rare compared to the other species found on male inflorescences of Phoenix reclinata. The elytral pattern and measurements are probably more variable than those provided in the description. The male from Kenya and the female from the Republic of South Africa are quite divergent regarding the shape of their rostrum, beyond what is expected for sexual dimorphism. Populations from these two areas are probably morphologically slightly divergent, similarly to what is observed in other species showing such distribution patterns. The penis and stridulatory plate of the only male available was unfortunately damaged during dissection and could not be used for the description.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFC67F0BD25AF6CE7CBFFB48.taxon	diagnosis	Diagnosis In the D. ephippiger group, this species can be distinguished by the combination of rostrum comparatively moderately long and downcurved (Fig. 30 C – D), only 3.5 × as long as wide in dorsal view in males (Fig. 30 A) and by the males lacking patterns of elytra and internal comb of elongate setae on protibiae. Derelomus costiger is similar to D. discus, but in the latter species males have a longer rostrum (4.75 × as long as wide) and bears combs of setae on protibiae (Fig. 31 D). It is also close to D. ephippiger, but the latter species exhibit a distinct dark pattern at the base of elytra (Fig. 32 A). The body of penis and the stridulatory plate are diagnostic for these species.

03AA8578FFC67F0BD25AF6CE7CBFFB48.taxon	description	Redescription (♂) MEASUREMENTS. Body length 2.5 – 2.8 mm. COLOR. Body integument uniformly pale brown or with apical ⅔ of rostrum, club and post ocular area dark brown, some specimens with median line of pronotum darker than rest of integument; dorsum with minute recumbent whitish setae, glabrous in appearance. HEAD. Rostrum as long as pronotum in lateral view, slightly and regularly downcurved; in dorsal view about 3.5 × as long as wide, integument densely punctate, forming 5 longitudinal carinae; antennae inserted at apical 1 / 5 of length in lateral view; head capsule densely punctate in dorsal view, forehead flat; eyes convex, exceeding lateral curve of head capsule in dorsal view; antennal funicle with first segment 2 × as long as wide, as long as segments 2 – 3 together, 3 – 7 transverse. PRONOTUM. Wider than long (W: L ratio: 1.50 – 1.66), widest near base, a little narrower there than elytra at humeral angles (0.82 ×), side rounded, converging apicad, forming notch and blunt tooth near middle of length; apical constriction distinct, about as deep as width of scape in middle of length; integument with punctures rounded, space between punctures rough, shiny, micropunctate, wider or narrower than diameter of punctures in middle, narrower laterally. METATHORAX. Metanepisterna with recumbent white setae, non-contiguous. ELYTRA. A little longer than wide (W: L ratio: 0.84 – 0.92); sides strongly convex, widest near basal 2 / 5 of length; humeri not distinct from the lateral curvature of elytra; apex rounded, notched or jointed at level of suture; striae with punctures about ⅓ to ¼ as wide as width of interstriae; interstriae flat, 5 slightly raised on basal 3 / 5 of length; scutellar shield rounded, generally slightly darker than elytra, coated with small recumbent scales not concealing integument. ABDOMEN. Underside uniformly pale brown, with minute recumbent whitish setae, not contiguous. Stridulatory plate with lines of 7 – 8 granules about ⅔ × as long as median line from base, space between granules 1 – 2 × as wide as diameter of a granule. Central sclerotized area slightly longer than wide, truncate at base (Fig. 30 F). LEGS. Profemora moderately thickened near middle of length; protibiae with external margin straight, internal bisinuate, setae on apical half of internal margin recumbent, short, not contrasting with the setae of the rest of tibiae; claws simple. TERMINALIA. Body of penis elongate (W: L ratio: 0.23), about 1.5 × as long as apodemes; sides slightly convex in dorsal view, widening regularly from base to apical ⅓, from there narrowing apicad, apex rounded; in lateral view curvature moderate but stronger in basal ½ of length, width narrowing regularly from basal ½ of length to apex, apex bisinuate (Fig. 30 E). Sexual dimorphism Females can be distinguished from males by the rostrum which is slightly longer (1.15 × as long as pronotum in lateral view) and narrower (Fig. 30 D). The antennae are inserted at apical ⅓ of rostrum in lateral view (¼ in males). Elytra of females are also more elongate (W: L ratio: 0.70) than in males (Fig. 30 B). Variation This species varies in color geographically. Populations from the Republic of South Africa have the rostrum, the post-ocular area and the club dark brown while those from west Africa (Ivory Coast and Senegal) are uniformly pale brown. These variations are not associated with divergent external and internal morphology in specimens examined.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFC67F0BD25AF6CE7CBFFB48.taxon	biology_ecology	Life history Adults of this species were collected in various sites on male inflorescences of Phoenix reclinata (Arecaceae), which probably constitutes the substrate for the larvae (Fig. 30 H). It has been sporadically collected on flowers of Buddleja auriculata Benth. (Scrophulariaceae). Adults are attracted by UV lights. This species is the most abundant among those found on male flowers of P. reclinata, at least in the Republic of South Africa. Adults were collected all year round.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFC67F0BD25AF6CE7CBFFB48.taxon	distribution	Distribution In our current knowledge, this species is known from Angola, Comoros and La Reunion Islands, Ivory Coast, Kenya, Mozambique, the Republic of South Africa, Senegal, USA (Florida) and Zimbabwe, but its host is widely distributed in eastern and western Africa, and it is likely that this species is more widespread. In La Reunion Island, this species has only been collected since 2010, suggesting a rather recent introduction on this island (E. Lemagnen pers. com.). This species has also been introduced to North America in recent years.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFC67F0BD25AF6CE7CBFFB48.taxon	discussion	Remarks Derelomus costiger was described based on a series of 6 male and 3 female specimens without designation of a holotype (Marshall 1958). In the collection housed at NHMUK, the type series from Stellenbosch was located. A male of this series bearing a red type label is designated as the lectotype for Derelomus costiger Marshall, 1958 [here designated] and was relabelled accordingly. The rest of the series was labelled as paralectotypes. Psilocaulus elatus Richard, 1958 is a derelomine weevil described from Comoros Islands a few months after Marshall’s description of D. costiger. The examination of the holotype of this species revealed no difference with the lectotype and paralectotypes of D. costiger. As a result, the species name Psilocaulus elatus Richard, 1958 is proposed as a junior synonym of Derelomus costiger Marshall, 1958 [new synonymy].	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFC27F0AD244F1C47DC2F81A.taxon	diagnosis	Diagnosis In the D. ephippiger group, this species can be distinguished by the uniformly pale brown pronotum and elytra in the males, their shape almost forming a disc, and the comb of erect setae on the protibiae (Fig. 31 D). It is closest to D. ephippiger and D. costiger, but the rostrum is longer than in those two species which also lack a comb on the protibiae in the males. The body of the penis and the stridulatory plate are diagnostic in all these species. Females are unknown.	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

Males have costate 5 th elytral interstriae (all interstriae flat in females).	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.

03AA8578FFCD7F01D223F4097CC3FD2D.taxon	discussion	Remarks In Schoenherr’s collection housed at NHRS, 2 male and 1 female specimens bearing a red type label and pinned in the box under the label “ ephippiger Gyll ” in the genus Derelomus were located. These specimens agree with the description given by Gyllenhal: “ Elytra (…) plaga lata, communi, brunnea, a basi paulo ultra medium extensa, ornata [elytra bearing a large brown band from base to beyond middle of length] ”, and no other specimen can be related to this peculiar feature in the box. As a result, one of the males of this series is designated as the lectotype for the species name Derelomus ephippiger Gyllenhal, 1836 [here designated] and was relabelled accordingly. The other two specimens were labelled as paralectotypes. There has been a confusion on the type locality of the specimens used to describe this species: the original description states that the specimens are from the Cap. Bonae Spei. [Cape of Good Hope, South Africa] and were provided by C. Quensel, but the labels under each specimen bear the locality “ Barbaria? Quensel ” an ancient term for the northern coast of Africa, extending from Morocco to Libya. Quensel never travelled to the Republic of South Africa and no specimens related to this species were ever collected in this country, suggesting that the type locality reported in the original description is erroneous. Moreover, this species appears absent from North Africa as well. The type locality for this species is thus left as uncertain. In our current knowledge, this species appears restricted to tropical Africa, from Senegal to Gabon. In the collection housed at MNHN, two female specimens labelled “ Gabon ” and corresponding in all aspect to the description of Hustache for Derelomus auberti were located. One of the specimens was designated as the lectotype for Derelomus auberti [here designated] and was labelled accordingly. The second specimen was labelled as a paralectotype. The rest of the series reported in the original description (ca 10 specimens) could not be located. The comparison between these lectotypes with the female lectotypes of D. ephippiger revealed no difference. As a result, the species name Derelomus auberti Hustache, 1932 is proposed as a junior synonym of Derelomus ephippiger Gyllenhal, 1836 [new synonymy].	en	Haran, Julien M., Benoit, Laure, Dufaÿ, Mathilde, Procheş, Serban, Kergoat, Gael J.
