03EB2068C85AFFDBFC18FBCBFAE4803A.taxon	discussion	(see below, key to the adults of subtribes of Chlaeniini Brullé, 1834) NOTES ON TRIBAL CHARACTERIZATION OF CHLAENIINI Regarding delimitation of Chlaeniini, a tentative diagnosis was recently given by Guéorguiev (2014: 89). That included common traits for the Carabidae Conchifera (sensu Jeannel 1949 b) as well as distinguishing tribal features. However, in the course of the current study, we established three features of tribal significance (Guéorguiev ibid.), namely 1) the elytron with internal plica; 2) metepisternum laterally coadunate with elytral epipleuron; and 3) stria 7 distinct to apex, not uniformly present in all representatives of the tribe. These character states are only useful as supplemental traits given the context and restrictions provided below. 1) As stated by Jeannel (1949 a) and verified herein the crossed elytral epipleuron is present in Chlaeniina (except for Grundmannius) and absent in Callistina. 2) The coadunate metepisternum and elytral epipleuron is a feature to consider with some caution. Based on a comprehensive study of the morphology of carabid taxa from different tribes and on an earlier statement of Habu (1956), Bousquet (1996: 449) stated that “ I have found this feature in all species of oodines and panagaeines studied and in some species of Chlaeniini. Likely the character state has been secondarily lost in several chlaeniine lineages ”. Ober & Maddison (2008) investigated the phylogenetic relationships among the harpalinae tribes using data from two nuclear loci and found that in most trees, oodines, chlaenines, panagaeines, and the genus Dercylus Laporte, 1832 form a clade. Given the Ober & Maddison investigations and pygidial gland defensive secretion data, Bousquet (2012: 53) then stipulated anew, now with improved evidential support, that the complex of Panagaeini – Chlaeniini – Oodini “ possibly constitute a clade since the adults (except in some chlaeniines) have the metepisterna coadunate with the elytral epipleura, a synapomorphic condition that has probably been secondarily lost in some chlaeniine lineages ”. However, no study has explored the distribution and extent of this character across all relevant taxa. What is known shows it is absent in representatives of the two callistine genera, Callistus and Callistomimus (see Terada & Wu 2018: 5, fig. 3 H). Among the taxa from Chlaeniina we studied, the appearance of the character varies. In some species the coadunation is obvious (Chlaeniellus Reitter, 1908, Chlaeniostenus Kuntzen, 1919), in others – less noticeable (Amblygenius La Ferté-Sénectère, 1851 and some Pleroticus Péringuey, 1896), and it is ambiguous or appears to be lacking in some (Callistoides, some Stenochlaenius Reitter, 1908). To avoid incorrectly scoring this state care must be taken to note the condition of the specimen. If present, the state can be seen when both the sternal and elytral structures are in close proximity to each other. It is the case when the elytra are closely retracted and the lateral margin of the anterior part of the metepisternum forms a more or less distinct protrusion that covers the paired site on the medial margin of the elytral epipleuron. If the lateral margin of the metepisternum does not cover the medial margin of the elytral epipleuron then the state of the character can be difficult to ascertain though it is present. Compare the Figure 3 A, B and Figure 12: the first two figures show “ unnatural ” states or artifacts of preservation where the metepisternum does not reach the epipleuron though both structures lie on the same level (Fig. 3 A) or are concealed under the epipleuron (Fig. 3 B). In Figure 12 the “ natural ” condition is shown - the metepisternum is tightly retracted on epipleuron. 3) In most chlaeniine genera, stria 7 is well-marked along the whole elytron length, including near the apex. However, Callistus lunatus and some species of Holosoma have stria 7 obliterated apically. In Hololeius ceylanicus stria 7 is usually hardly distinguishable in basal three fourths and well-perceptible on apical one fourth only.	en	Guéorguiev, Borislav, Will, Kipling (2025): A new genus and tribal placement for Ceneus speculiferus Fairmaire, 1879, comments on Grundmannius Basilewsky, 1965, Mirachlaenius Facchini, 2011 and Stenoodes Basilewsky, 1953, and a key to the Oriental and Australasian genera of Chlaeniina Brullé, 1834 (Coleoptera, Carabidae).

03EB2068C859FFD7FC22F96DFBC38748.taxon	discussion	MONOPHYLY AND RELATIONSHIPS At least four outstanding autapomorphies that are present in Lapitachlaenius n. gen., support the distinctiveness of the new genus. Three of them are features of the elytra, and one of the pronotum disc: 1) each elytron with a glistening, mirror-like area; 2) interval 3 with four to seven large, foveate setiferous punctures; 3) interval 8 distinctly interrupted into two portions along its length and 4) pronotum disc with broad and shallow paramedial, parentheses-like impressions that join with the baso-lateral impressions. These traits along with some other peculiar features (see Diagnosis), unusual among chlaeniine carabids, provide solid basis for recognition of the new genus. We examined selected character states and their distribution among the species of Chlaeniina from the Australasian and Oceania regions (Table 3) east of the Lydekker Line. This line demarcates the edge of the Sahul continental shelf and is used as an outermost boundary for delimitation of the typical Australasian fauna from the Oriental fauna (Beron 2015). In total, 31 representatives of the subtribe Chlaeniina Brullé, 1834 have been reported to occur east of the Lydekker Line, 20 of them are microendemic species (Table 3). These locally endemic species are known from: Micronesia, incl. Ogasawara Isl., Southern Mariana Isl. and Palau Isl. (5 species in Chlaenius; cf. Darlington 1970 a; Kasahara 1991; Mandl 1992), New Guinea with New Britain (13 species in Chlaenius and Hololeius; cf. Sloane 1920; Darlington 1968; Azadbakhsh & Kirschenhofer 2019), Aru Islands (1 species of Chlaenius; Häckel et al. 2023), Solomon Islands (5 species in Chlaenius; cf. Emden 1937; Darlington 1968, 1970 b), Australia (10 species of Chlaenius and Hololeius; Sloane 1920; Moore 1987), Lord Howe Island (1 species in Chlaenius; cf. Moore 1985, 1992), Norfolk Island (2 species in Chlaenius; cf. Moore 1985), New Caledonia (4 species of Chlaenius, cf. Fauvel 1882; Chaudoir, 1883; Heller 1916; Sloane 1920; Darlington 1968; Kirschenhofer 2002, 2015), Vanuatu (3 species in Chlaenius and Lapitachlaenius n. gen.; cf. Emden 1937; Moore 1985), Fiji (4 species in Chlaenius and Lapitachlaenius n. gen.; cf. Darlington 1968; Evenhius 2007; present study), Samoa (2 species in Chlaenius; cf. Csiki 1915; Andrewes 1927), Tahiti (1 species in Chlaenius; cf. Darlington 1970 a). No representative of the subtribe is known from New Zealand. Larochelle & Larivière (2001) stated that two Australian mainland Chlaenius species were introduced to Lord Howe and Norfolk Islands and that it is likely that will be discovered in New Zealand in time. We found that the adults of Lapitachlaenius n. gen. share some specific features with the “ bimaculatus ” group of subgenus Lissauchenius W. S. MacLeay, 1825. The last group includes four taxa in Australasia and Oceania – Chlaenius bimaculatus pongraczi Jedlička, 1951, Ch. flaviguttatus (W. S. MacLeay, 1825), Ch. olthofi Darlington, 1968 and Ch. rufifemoratus (W. S. MacLeay, 1825) as first and third taxa are endemics in New Guinea (Table 3). Species of “ bimaculatus ” group and species of Lapitachlaenius n. gen. share: antennomere 3 not or only slightly longer than antennomere 4; mandibles relatively short, as long as wide, moderately arcuate towards tips (Fig. 2 A); abdomen largely smooth and glabrous medially; male front femur with a small tooth-like tubercle below (Fig. 1 D) (character presumed to have been secondarily lost in L. specularis n. comb.). For more on the distribution of the enumerated characters in some taxa of the “ bimaculatus ” group see Darlington’s (1968) “ Key to species of Chlaenius of New Guinea ”. It is assumed that the six species noted above share the state of having a simple mentum tooth that is rounded at apex. Among the taxa of “ bimaculatus ” group the simple mentum tooth is only documented in Ch. olthofi (Darlington ibid.). A plausible hypothesis of the evolution of the genus is that there was a single, eastward, long-distance dispersal event (Gillesbie et al. 2012), perhaps in the Early Miocene (or during an earlier geological epoch), of a common ancestor of Lapitachlaenius n. gen. and the “ bimaculatus ” group of Lissauchenius. Presumably, after the colonization event the lineage experienced remarkable modifications in terms of the pronotum relief, elytral relief, and elytral setiferous setation, all well before both the Fiji-Vanuatu split (Martin 2013) and then subsequently underwent species-level differentiation. Formation of the two species is potentially a relatively recent event. It is likely the result of the separation of a widespread, ancestral population in the course of the breakup of the formerly continuous Vityaz Arc that separated into the Vanuatu and Fijian land masses, with the North Fiji Basin opening between them during the subduction processes in the Miocene (Martin 2013; Gill et al. 2022). The breakup of this arc acted as a significant vicariance event and driver for speciation in various groups (Liebherr 2005; Ferguson et al. 2023; Saxton et al. 2023).	en	Guéorguiev, Borislav, Will, Kipling (2025): A new genus and tribal placement for Ceneus speculiferus Fairmaire, 1879, comments on Grundmannius Basilewsky, 1965, Mirachlaenius Facchini, 2011 and Stenoodes Basilewsky, 1953, and a key to the Oriental and Australasian genera of Chlaeniina Brullé, 1834 (Coleoptera, Carabidae).

03EB2068C855FFD3FC97FAACFA2F842A.taxon	etymology	ETYMOLOGY. — The name “ speculiferus ” is not a properly formed Latin word [ICZN Art. 26] though it appears to be based on the Latin word speculifer (- a, - um). Both speculifer and speculifera can be nouns for “ mirror-bearer ”. Also, these and speculiferum can be adjectival for “ mirror-bearing ”. However, since “ speculiferus ” is not a Latin word and Fairmaire did not specify how it was being used, it must be treated as a noun in apposition [ICZN Art. 31.2.3] that is indeclinable and retains its original spelling even if moved to a feminine genus. Csiki’s (1930) use of “ Prosopogmus speculifer ” is considered an unjustified emendation and so we use Fairmaire’s original spelling.	en	Guéorguiev, Borislav, Will, Kipling (2025): A new genus and tribal placement for Ceneus speculiferus Fairmaire, 1879, comments on Grundmannius Basilewsky, 1965, Mirachlaenius Facchini, 2011 and Stenoodes Basilewsky, 1953, and a key to the Oriental and Australasian genera of Chlaeniina Brullé, 1834 (Coleoptera, Carabidae).

03EB2068C851FFD2FC80F94DFAEE86C8.taxon	discussion	REMARKS This species was described by Emden (1937) from the island of Erromango, the fourth-largest island in the Vanuatu archipelago. The author provided a rather good, for that time, description and placed it in the genus Chlaenius. In his discussion, Emden stressed several important features: 1) elytron with a roughly triangular specular spot, broadly reaching the suture, touching the tip of the 4 th or 5 th lateral striae, shiny around the 2 nd punctured of the 3 rd interval and the varying color nuances in and around the spot; 2) pronotum disc basal impressions continuing towards the front border as indistinct S-shaped impressions; 3) 3 rd elytral stria with 5 - 7 engraved punctures, the first and second of which lie in the “ mirror ” spot; and 4) underside and upper side of body glabrous. At the end of description, the author expressed suggestion that the species may belong to a separate genus: “ Die gerunzelten Mandibeln, die wohl sogar die Aufstellung einer besonderen Gattung rechtfertigen würden, und der Spiegelfleck trennen die Art von allen bekannten [The wrinkled mandibles, which would probably even justify the establishment of a separate genus, and the mirror spot separate the species from all known] ”. The careful examination of the Emden’s description as well as images of and information about characters in the holotype and two paratypes (see the above “ Type material ”) show that this species shares with Lapitachlaenius speculiferus n. comb. all the autapomorphies of the new genus. These species appear very closely related based on their shared morphological similarities and that they inhabit very close, though isolated islands. Based on this evidence we concluded both species form a clade we treat as a genus. On the other hand, several clear distinctions between the two species (see Diagnosis under L. speculiferus n. comb.) are evidence that the two taxa are distinct and plausibly reproductively isolated species.	en	Guéorguiev, Borislav, Will, Kipling (2025): A new genus and tribal placement for Ceneus speculiferus Fairmaire, 1879, comments on Grundmannius Basilewsky, 1965, Mirachlaenius Facchini, 2011 and Stenoodes Basilewsky, 1953, and a key to the Oriental and Australasian genera of Chlaeniina Brullé, 1834 (Coleoptera, Carabidae).

03EB2068C850FFC9FC47F96EFDCF86A8.taxon	discussion	REMARKS The species was described in the genus Ectenognathus Murray, 1858 from “ Middle Limpopo ”, based on single female specimen (Péringuey 1896). This generic assignment seems to have been made by Péringuey as a result of apotypic traits present in both of his species and the type species of the genus, E. dryptoides Muray, 1858 (Murray 1858): very long and glabrous last two joints of labial and maxillary palpomeres; simple mentum tooth, rounded at tip; long and subfalcate mandibles (E. dryopoides has mandibles much more falcate and curved at apex than mandibles of G. dispar); moderately emarginate labrum; narrow, subcordiform pronotum, with sides more or less broadly reflexed behind. Nearly 70 years later the situation changed after more data on the morphology of Chlaeniini have been amassed. Studying one male specimen of E. dispar with broken protarsomeres and comparing it with the type of E. dryptoides, Basilewsky (1965) established the genus Grundmannius. He made this decision because of the presence of simple, non-crossed elytral epipleuron and the absence of the lateral setiferous punctures on pronotum in the first species. Accordingly, he placed the new genus in subtribe Callistina, with species that possess the two aforementioned characters. Contrary to this, the presence of crossed elytral epipleuron in E. dryptoides – “ the reflexed margin of the elytra, particularly towards the apex ” (see Murray 1858) supports placement of this species as a member of subtribe Chlaeniina. Based on the thesis / antithesis 66 (61) of Basilewsky (1950: 51) we can provide two more distinctions between the monotypic genera Ectenognathus and Grundmannius. Both the maxillary palpomeres and tarsomeres dorsally are pubescent in the former genus whereas they are glabrous in the latter genus. Recently, Kirschenhofer (2010) supported the view of Basilewsky that the genus is a member of Callistina, but stated that G. dispar is a very characteristically distinct species in terms of its genital morphology and external characteristics and it should be placed in its own subtribe. Currently, Grundmannius is placed in tribe Lachnophorini (Lorenz 2025). Such a placement might have been based on a few external characters, such as falciform mandibles and lack of elytral plica, which are found in lachnophorines and lacking in most chlaeniines (Table 4) as well as accepting the supposition by Chaudoir (1876: 8 - 9; see also Basilewsky & Grundmann 1955: 201) that Ectenognathus may be a lachnophorine. Additional arguments for such an assignment can be inferred from the view that the presumed basal chlaeniines and basal odacanthines (to which lachnophorines were referred before the work of Liebherr 2016) share a similar ground plan of the body and similar way of life (Baehr 1996: 263, 2005: 183). To ascertain the relationships of Grundmannius the comparative method was applied, looking for similarities and differences of the morphology of adults. Two sets of characters were investigated: the first set focused on features thought to likely resolve the tribal affinity of the genus in regard to Chlaeniiini and Lachnophorini (Table 4) and a second set to assign the genus subtribal position within Chlaeniini (Table 5). For character states in Lachnnophorini, we carefully surveyed the works of Ball & Hilchie (1983), Liebherr (1988, 2016), Liebherr & Will (1998), Erwin & Zamorano (2014) and Moret & Ortuño (2017). In summary (Table 4), Grundmannius is much more similar to chlaeniines sharing with some or all of them: an obtuse tip of terminal palpomeres; glabrous maxillary apical palpomere; glabrous antennomere 2; one supraocular setiferous puncture; biperforate anterior coxal cavities (character state unknown in lachnophorines); metepisternum coadunate with elytral epipleuron; adhesive vestiture of male protarsomeres 1 - 3 of “ spongy ” type; rounded elytral apex. Among the characters enumerated, there are three of tribal importance for Chlaeniini – the coadunate metepisternum, the adhesive vestiture of male protarsomeres 1 - 3, and single supraocular setiferous puncture. Grundmannius and Lachnophorini share only the lack of elytral plica. However, the last character state occurs in the chlaeniine subtribe Callistina. Grundmannius dispar and representatives of the subtribe Chlaeniina share many important features not found in species of Callistina (Table 5), such as: smooth macrosculpture of cuticle; pubescence absent from integument; glabrous antennomere 2; narrow and blunt tip of ultimate palpomeres; glabrous interior side of penultimate labial palpomere; two-segmented galea; mentum tooth present; pronotal epipleuron reflexed at rear; presence of discal punctures in elytral interval 3; metepisternum coadunate with elytral epipleuron. Among taxa placed in the tribe Chlaeniini, only G. dispar and species of Callistina share the lack of the pronotal posterolateral setiferous punctures and elytral epipleuron not being interrupted by a plica. The character evidence supports classifying the genus as a member of the subtribe Chlaeniina, not in Callistina (cf. Basilewsky 1965). We hypothesize that the absence of the elytral epipleural plica and the lack of the posterior pronotal setiferous punctures in Grundmannius and Callistina represent independent character losses. The spermatheca of G. dispar remains unknown and given its utility in other taxa it is likely that this structure will yield evidence regarding the taxonomic position of this species within chlaeniines.	en	Guéorguiev, Borislav, Will, Kipling (2025): A new genus and tribal placement for Ceneus speculiferus Fairmaire, 1879, comments on Grundmannius Basilewsky, 1965, Mirachlaenius Facchini, 2011 and Stenoodes Basilewsky, 1953, and a key to the Oriental and Australasian genera of Chlaeniina Brullé, 1834 (Coleoptera, Carabidae).

03EB2068C84BFFCAFC41FD8AFE598669.taxon	discussion	TAXONOMIC SUPPLEMENT (BASED ON SPECIMEN EXAMINED) Added to the information noted by Facchini (2011: 348 - 350) in the original description based on two male specimens, we report following new morphological data. Stipes with long dorsal seta, as long as length of stipes; antennomere 2 with short ventral seta. Maxilla with two-segmented galea. Penultimate labial palpomere glabrous, except for two, minute apical ventral setae. Mentum with two long, paramedial setae; mentum tooth truncate at apex. Submentum with two very long, lateral setae. Pronotum without setal fringe along basal edge. Basal and lateral margins of elytra forming small denticle at humerus; left elytron with two small, nearly imperceptible, discal setiferous punctures, first puncture in anterior fifth on interval 3 adjacent to stria 3, second puncture in center of interval 3 near apical end, closer to apex than to suture, right elytron without discal punctures (this character state in partial accordance with Facchini 2011: 350 who stated that just one discal pore was present on one of the elytra); parascutellar puncture large, foveate, at angular base of stria 1; apical portion of stria 7 with three setiferous punctures, terminal puncture closer to apex than to suture and distant from two anterior punctures; umbilicate series consisting of 21 - 23 setiferous punctures of various sizes. Prosternum with shallowly impressed median sulcus; prosternal process wide at apex, unbordered. Metepisternum wider than long, with anterior border longer than internal border, without sublateral longitudinal sulcus. Protrochanter with anterior seta. Mesocoxa with one posteromedial seta and one or two lateral setae; mesotrochanter with posterior seta. Metacoxa with only anterolateral seta. Metafemur without posterior setae. Abdominal ventrites 3 - 5 with ambulatory setae each side; last ventrite with four setae in female. Pygidial glands system with a bilobed reservoir – larger reniform lobe (main part of reservoir) and smaller spherical dorsal lobe (Fig. 15). Collecting duct arising from ventral basal part of a narrow channel (here named “ reservoir junction channel ”) connecting main lobe of reservoir with efferent duct. Laterotergite with eight to ten small distal setae on posterior margin (Fig. 16 A). Gonocoxite 1 broad, slightly longer than wide, apex without setae. Gonocoxite 2 elongate, slightly curved, base well protruding outward, without ensiform setae, with two close, very fine and short nematiform setae (hardly visible at highest magnification), situated in an elongate pit-like depression near apex of gonocoxite (Figs 16 A, B). Spermathecal complex with small bursa copulatrix; spermatheca narrow and very long, slightly but clearly differentiated to very long seminal canal and short, coiled receptaculum (Figs 17 A, B); spermathecal gland elongate, with spermathecal canal slightly differentiated, connected near middle of receptaculum; common oviduct with villous canal. REMARKS Since the original description (Facchini 2011), the specimen we examined is the first female and the third individual known of M. barbarae. Study of this material allowed us to make a contribution to the morphology of the species especially regarding the female reproductive and pygidial defensive gland structures, Additionally, we report on some external characters not discussed in the original description. Forsyth (1972: 299 - 300) discussed a compound reservoir of the pygidial gland with a main reservoir and a dorsal lobe that occurs in the tribes Harpalini Bonelli, 1810, Licinini Bonelli, 1810, Platynini Bonelli, 1810, Anthiini Bonelli, 1813 and Dryptini Bonelli, 1810 (ibid. 288, fig. 42). Pygidial gland dorsal lobes are also present in Sphodrini Laporte, 1834 (Will et al. 2010) and some Pterostichini (Baehr & Will 2019). Expanded and lobe-like structures on the efferent duct is known from some Abacetini Chaudoir, 1873 (Will et al. 2000). An independent evolution of a separate main reservoir and dorsal lobe connected by a reservoir junction channel is found in species of Sphodrosomus Perroud, 1864 (Pterostichini) from New Caledonia (Will 2006). A reservoir without a dorsal lobe is found in Chlaeniini and most other carabid tribes (Balestrazzi et al. 1985; DazziniValcurone & Pavan 1980; Will 2000). Given the paucity of studies of the pygidial gland system for most species of carabids, it is not surprising that our investigation revealed a bilobed gland reservoir in the genus Mirachlaenius. What is even more interesting in the pygidial gland system of this genus, it is the presence of a narrow channel (Fig. 15) that links between the main reservoir and the efferent duct. This specific structure is named reservoir junction channel. This is the first such structure observed in Chlaeniini and among carabids the only known analogous form is that of the pterostichine Sphodrosomus.	en	Guéorguiev, Borislav, Will, Kipling (2025): A new genus and tribal placement for Ceneus speculiferus Fairmaire, 1879, comments on Grundmannius Basilewsky, 1965, Mirachlaenius Facchini, 2011 and Stenoodes Basilewsky, 1953, and a key to the Oriental and Australasian genera of Chlaeniina Brullé, 1834 (Coleoptera, Carabidae).

03EB2068C848FFCAFED2F9CDFBDF858D.taxon	discussion	TAXONOMIC SUPPLEMENT (BASED ON HOLOTYPE) The following additions and specifications are added to the original description. Stipes with long and fine dorsal seta, longer than length of stipes; antennomere 2 with long ventral seta. Clypeus concave in front, with two clypeal setae; clypeus fused with frons (no frontoclypeal suture). Mentum with two long paramedial setae. Submentum with two long lateral setae. Pronotum anterior and posterior transverse impressions barely distinct only medially; basal margin without bead, basal edge without setal fringe (Fig. 18 B). Prosternum with median longitudinal sulcus shallowly impressed. Parascutellar seta present, small, located at level of elytral stria 2; parascutellar striole long, not joining elytral stria 1, almost reaching medial end of basal margin. Elytral interval 3 with two discal setiferous punctures near stria 2, first more evident, situated in medial fifth of elytral length, second, less perceptible than first, located in posterior fourth (Fig. 18 A). Stria 8 distinct in anterior four-seventh where deeper than striae 1 - 7. Intervals 8 and 9 normal in anterior four-seventh, modified towards apex as interval 8 elevated, forming a ridge, 9 deepened and widened backwards, forming a marginal furrow (Fig. 18 C). Mesotrochanter with seta. Mesotibia without submedial assemblage of setae. Metafemur with long basal posterior seta opposite metatrochanter. REMARKS Stenoodes was introduced for the distinctively autapomorphic species S. jeanneli (Basilewsky 1953). The genus was originally placed in the tribe Oodini though the author (ibid.) did not report on the unique modifications in elytral intervals 8 and 9 (see Introduction) that are the most recognizable morphologic features of the tribe. Recently, the genus was categorized as a representative of the tribe Chlaeniini and listed immediately after Hololeius (Lorenz 1998, 2005). This move was made because “ Stenoodes was strikingly looking like an Indian Hololeius, that may have been unknown to Basilewsky ” (Wolfgang Lorenz, pers. comm.). Careful study of the holotype of S. jeanneli revealed that it possesses the modifications in elytral intervals 8 and 9 typical of Oodini and that its integument is glabrous outside of the typical sensory setae, consistent with the original placement of Basilewsky (1953). The presence of a basal posterior seta on hind femur and lack of mesotibial submedial assemblage of setae (for the second character see Guéorguiev & Schmidt 2016) both are likely plesiomorphic conditions in this group of carabids. That led to supposition that Stenoodes is most likely an early branch in the tribe. The other oodine groups that possess basal posterior seta on metafemur are Oodinus Motschulsky, 1865 and Stenocrepis Chaudoir, 1857 (Bousquet 1996), three Australian species of Nanodiodes Bousquet, 1996 as well as two of the four recognized species groups of Brachyodes Jeannel, 1949 (unpublished data). While the representatives of the first genus are mainly restricted to the world tropical regions, with two species occurring subtropical areas of the southernmost United States, members of Stenocrepis inhabit the New World from southern Ontario south to Uruguay and Argentina, including the West Indies (Spence 1983; Bousquet 1996, 2012). Taxa of Brachyodes live mainly in the tropics of the Old World, with only a few species reaching southern skirts of the Palaearctic Region (Bousquet 2017; unpublished information).	en	Guéorguiev, Borislav, Will, Kipling (2025): A new genus and tribal placement for Ceneus speculiferus Fairmaire, 1879, comments on Grundmannius Basilewsky, 1965, Mirachlaenius Facchini, 2011 and Stenoodes Basilewsky, 1953, and a key to the Oriental and Australasian genera of Chlaeniina Brullé, 1834 (Coleoptera, Carabidae).
