03EC5B27FFA8A42CB420FDF0FEC28D89.taxon	discussion	REMARKS This genus is easily recognized by the presence of a stridulatory organ, in the form of a band of chitinized scales on the side of the abdomen along the margin of the fused tergites 1 and 2. The adults are usually completely black with white or yellow halter (except for the Neotropical species A. fusca Spencer, 1963 with black halter and A. insolens Spencer, 1963 with brownish halter), usually have three or more pairs of dc (a few species with only two well-developed postsutural dc and a third small one. Agromyza megaepistoma Sasakawa, 2005 from Ecuador has only two postsutural dc with rarely a third small one) and well-developed prsc. A single male specimen of Agromyza was collected on the Mitaraka massif (Boucher & Pollet 2021) and represents a new species that is described below.	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFA8A42CB5F6FB32FBD28E0B.taxon	discussion	REMARKS This new species has a characteristic ejaculatory apodeme with a narrow blade as seen for A. simillima Spencer, 1963 from Brazil (Spencer 1963). The two species also share only two well-developed dc. The phallus of A. simillima has never been illustrated. Pictures of the phallus (on permanent mount) and habitus of the holotype specimen of A. simillima (Fig. 2), provided by the Natural History Museum, London (NHM), confirm that the two species are different. The distiphallus of A. simillima is much narrower and elongate (Fig. 2 A). Furthermore, the arista of A. simillima is described as conspicuously plumose (Spencer 1963), which is not the case in A. mitarakensis Boucher, n. sp. The head of the holotype of A. simillima is glued to a cardboard point separated from the rest of the specimen, but the aristae are missing (Fig. 2 C). The phallus of A. mitarakensis Boucher, n. sp. is similar to that of A. animata Spencer, 1973 from Costa Rica (Spencer 1973 a), but the latter species has three well-developed dc and darker antennae. The ejaculatory apodeme of A. animata has not been described nor illustrated yet. Agromyza mitarakensis Boucher, n. sp. was listed as morphospecies Agromyza Mit- 1 in Boucher & Pollet (2021).	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFA8A42EB6B9F8B4FB7C8C29.taxon	discussion	REMARKS Most species of Calycomyza are characterized externally by a yellow frons, dark antennae, yellow notopleuron, dark scutellum, pale yellowish halter and the presence of only two postsutural dc. However, exceptions exist, such as: C. meridiana (Hendel, 1923), a widespread neotropical species, with yellow third antennal segment; C. devia Spencer, 1973 from Venezuela and Costa Rica with a brownish frons and darker notopleural areas; C. compositana Spencer, 1973, C. illustris Spencer, 1973, C. steviae Spencer, 1973, C. parilis Spencer, 1973 and C. palmaris Spencer, 1973, all from Venezuela, have 3 + 1 dc. The latter two species also feature a brown halter. A distinctive characteristic of the genus is the male genitalia with the epandrium and surstyli having a patch of short strong spines. Seven specimens of Calycomyza were collected on the Mitaraka massif, representing four species (Boucher & Pollet 2021). Two of them were represented by females only (Boucher & Pollet 2021) and their identity could not yet be confirmed. These two species are characterized by the presence of 3 + 1 dc (two weaker anterior ones). Of the other two species, one represents C. grenadensis Zlobin, 1996 (morphospecies Calycomyza Mit- 1 sensu Boucher & Pollet 2021), which was previously known from Grenada (Zlobin 1996 a) (see below), and the other (morphospecies Calycomyza Mit- 2 sensu Boucher & Pollet 2021) represents a new species, which is described below. Only one species, Calycomyza lantanae (Frick, 1956) was previously recorded from French Guiana (Anonymous 2018).	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFAAA420B6A5FA95FE718EEB.taxon	discussion	REMARKS There are slight differences between the Mitaraka specimens and the original description of the species. They include the orbital plate darkened to upper ors only, continuing faintly on lateral margin to lower ors in male (Fig. 1 A) (darkened to lower ors in original description) and the face darkened at base of antennae (face yellow in original description). Other characteristics worth mentioning, but not part of the original description, are the presence of three postsutural dc, including two well-developed and a much shorter anterior dc; and the mid tibia with three short lateral setae. Until now, this species was only known from the type material from Grenada.

03EC5B27FFA4A422B68BF9D4FC5C8BC8.taxon	discussion	REMARKS The male genitalia of this new species are most similar to those of C. verbenivora Spencer, 1963, which feeds on various plants in the family Verbenaceae. The type specimen of the latter species from Venezuela, illustrated in Spencer (1963), apparently has the lower tubule broken off (see comment in Spencer 1973 b: 49), but the upper tubule is complete, and it is distinctly longer than the mesophallus, quite different from C. inselbergensis Boucher, n. sp. Another difference is the ring-like sclerite at the base of the distiphallus which is distinctly wider in C. inselbergensis Boucher, n. sp. Additional illustrations of the phallus of C. verbenivora from Argentina (Valladares 1981) and Peru (Korytkowsky 2014) more closely resemble the phallus of C. inselbergensis Boucher, n. sp. (except for the size of the ring-like sclerite), but C. verbenivora shows significant external differences that are diagnostic: calypter yellow with fringe partially to completely yellow; arista virtually bare; orbital plate bright yellow; and notopleuron, posterior half of postpronotum and upper posterior corner of anepisternum bright yellow. Externally C. inselbergensis Boucher, n. sp. is most similar to C. verbenae (Hering, 1951), a species known from southern United States and Brazil (Spencer 1963; Esposito 1994), but the male genitalia of the two species are distinct. Calycomyza verbenae is separated externally from C. verbenivora by the darker, distinctly black calypteral fringe and black face (Spencer 1963). Like C. verbenivora, C. verbenae feeds on species of Verbena L. and other plants in the family Verbenaceae (Benavent-Corai et al. 2005). This species was initially listed as morphospecies Calycomyza Mit- 2 in Boucher & Pollet (2021), along with an additional female specimen. After reconsideration, the female specimen is not included here as a paratype due to uncertain conspecificity. The female differs from the male by its yellow halter, yellow face, mid tibial setae that are further apart, and a shiny brown clypeus.	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFA6A422B6B3FCF3FC6C8CEA.taxon	discussion	REMARKS The genus Cerodontha is classified into seven subgenera (Butomomyza Nowakowski, 1967, Cerodontha, Dizygomyza Hendel, 1920, Icteromyza Hendel, 1931, Phytagromyza Hendel, 1920, Poemyza Hendel, 1931, and Xenophytomyza Frey, 1946). All subgenera have been recorded in the Neotropical region, except for Phytagromyza, which is exclusively Holarctic. The species are quite variable externally, but the male genitalia is characteristic with a well-developed mesophallus and long tubular distiphallus. In addition, all species in the genus Cerodontha have in common an L-shape sclerite inside the epandrium (the subepandrial sclerite or “ Langfortsatz ” of previous authors). A single specimen of Cerodontha was collected on the Mitaraka massif and belongs to the subgenus Dizygomyza. This subgenus is characterized by a large lunule and typically an enlarged first flagellomere in the male, although there are a few exceptions, including the new species described below.	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFA6A424B669F9D4FBC38856.taxon	discussion	REMARKS This species is most similar to the Costa Rican C. (Diz.) nigrihalterata Boucher, 2005 (Fig. 7). An attempt was made to have both species barcoded, which ultimately failed (Boucher & Savage 2022). Externally the two species have a few important similarities including the presence of only one ors and three ori, dark knob of halter, wing infuscated in cell R 1 and R 2 + 3, lunule and anterior orbital plate with silvery pubescence and mid tibia with a strong apical spine. The phallus of both species is also similar. The holotype of C. nigrihalterata illustrated in Boucher (2005) has the distal tubules of the phallus divergent, but it is parallelsided (as seen in C. (Diz.) pseudonigrihalterara Boucher, n. sp.) in a paratype shown in Fig. 7 C, D. Cerodontha (Diz.) nigrihalterata differs from the new species described here by having a projecting frons (Fig. 7 A), the palpus with normal setae, the first flagellomere slightly enlarged in the male (Fig. 7 B), tarsal segments paler yellow, mesonotum with three postsutural dc, the ejaculatory apodeme with a long and narrow stalk (Fig. 7 E, paratype (slightly different from ejaculatory apodeme in holotype illustrated in Boucher 2005 )) and apex of distal tubule more contiguous with tubule, not appearing as a separate sclerite. However, the unique characteristics that these species share make them distinct within the genus Cerodontha, suggesting a close evolutionary relationship.	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFA0A424B6A5FE71FBB78D89.taxon	discussion	REMARKS A total of 12 female specimens belonging to the genus Japanagromyza were collected on the Mitaraka massif, representing four morphospecies (Boucher & Pollet 2021) (Fig. 8 A-D). All these species have a metallic sheen characteristic of the genus. However, most of the Mitaraka Japanagromyza species (Japanagromyza MIT- 2; J. Mit- 3 and J. Mit- 4) lack the prsc normally present in this genus. Out of the 35 species of Japanagromyza recorded in the Neotropical region, (treating J. iridescens (Frost, 1936) and J. inaequalis (Malloch, 1914) as two distinct species [Spencer & Stegmaier 1973]), only five species (J. aldrichi (Frick, 1952); J. lonchocarpi Boucher, 2006; J. polygoni Spencer, 1973; J. desmodivora Spencer, 1966 and J. tingomariensis Sasakawa, 1992) lack these setae. Unfortunately, without male specimens the identification of the Mitaraka specimens could not be confirmed.	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFA0A425B6D0FB32FBB08EEC.taxon	discussion	REMARKS This is a very speciose genus, difficult to identify due to high morphological homogeneity across the species (both externally and in the male genitalia) and the lack of decisive diagnostic features. Most species are very small (often between 1.5 - 2.5 mm in wing length), usually yellow (frons, part of pleura and scutellum, sometimes legs) and black (mesonotum, part of pleura) in colour, with only some exceptions. For example, L. nigra Spencer, 1984 from Colombia has a dark frons and dark scutellum. Most Liriomyza males have a characteristic feature: the stridulatory organ present on the lateral membranous portion of the abdomen. This structure is sometimes pale and difficult to see and may be secondarily lost in a few species. A total of 15 specimens of Liriomyza were collected on the Mitaraka massif, representing three species. Two (Liriomyza Mit- 2 and Liriomyza Mit- 3) were represented by female specimens only (Boucher & Pollet 2021: table 2), and their identity remains doubtful. These two species have two or three posterolateral setae on the mid tibia, a character rarely seen in Neotropical Liriomyza species. The other species (Liriomyza Mit- 1) represented by nine females and three males represents a new species described below. Three Liriomyza species were previously known from French Guiana. These are widespread and well-known pest species: Liriomyza huidobrensis (Blanchard, 1926), Liriomyza trifolii (Burgess, 1880) and Liriomyza sativae Blanchard, 1938.	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFA2A427B403F9D4FDA48E0B.taxon	discussion	REMARKS Externally, this new species is most similar to L. sativae Blanchard, 1938, a species widely distributed in the Neotropical region (and elsewhere), and also recorded from French Guiana (EPPO 2022; Martinez & Étienne 2002; Ryckewaert 2003). These two species can be separated from each other by the male genitalia: in L. sativae, the mesophallus is much shorter than the distiphallus and the ejaculatory apodeme has a shorter stalk and wider blade. Also, the spine on the surstylus is subapical (see Lonsdale 2021). In lateral view, the phallus of L. touroulti Boucher, n. sp. is similar to that of L. geniculata Sasakawa, 1992 from Venezuela (Sasakawa 1992 a), but it is quite different in ventral view. Furthermore, the surstylus has two apical spines. Short DNA sequences (356 bp) were obtained from two female paratypes of L. touroulti Boucher, n. sp., with the following GenBank accession numbers: OK 623731 and OK 623719 (Boucher & Savage 2022).	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFBAA433B6A0F9D4FE178815.taxon	discussion	REMARKS Although the narrow, elongated hypandrium is unusual for this genus (broadly rounded in most Phytobia) and the phallus of this species is most similar to some Neotropical species of Japanagromyza, this new species belongs to the genus Phytobia on the basis of wing venation, the shape of the surstyli, the presence of 4 + 1 dc, and the presence of postgonites. This species was identified as morphospecies Phytobia Mit- 1 in Boucher & Pollet (2021).	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFB7A433B406FEB1FE528DC9.taxon	discussion	REMARKS This genus was originally erected for species having proclinate orbital setulae (in addition to other characters) which easily separate this genus from other similar agromyzid genera, especially Liriomyza. But the concept of the genus has evolved, now encompassing also species with upright or reclinate orbital setulae and some without orbital setulae. The colour is also variable with some species having the mesonotum and scutellum dark (typically greyish), while others feature a yellow scutellum and sometimes pre-scutellar area, like several Liriomyza species. However, unlike Liriomyza, male Phytoliriomyza do not possess a stridulatory organ. Most Phytoliriomyza have only three orbital bristles including two ors and one ori (some species, e. g., P. grandis (Spencer, 1963) from Brazil have two ors and three ori). The halter is often slightly darkened apically or completely brown and the male genitalia is usually distinctive with conspicuous spines on the surstyli and on the inner margin of epandrium. Only two specimens were collected on the Mitaraka massif (Boucher & Pollet 2021) which proved to belong to Phytoliriomyza jurgensi Spencer, 1983 originally described from Costa Rica (Spencer 1983) and later found to occur in Guadeloupe and St-Christopher (Étienne & Martinez 2003 a, b).	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).

03EC5B27FFB7A433B5F0FAF5FB058A08.taxon	discussion	REMARKS According to the original description (Spencer 1983), P. jurgensi has the first flagellomere and palpus black, and the tibiae and tarsi brownish black. In contrast to this, the Mitaraka specimens are paler, with the first flagellomere and palp yellowish brown in the male and brown in the female, and the tibiae and tarsi dark yellow. The Mitaraka specimens are also slightly smaller with a wing length of 1.2 mm in the male and 1.4 mm in the female (1.4 mm in male in original description) and they have 3 + 2 dc (Fig. 18 B) (3 + 1 dc in original description). Externally, P. jurgensi is most similar to P. scotica Spencer, 1962 (Neotropical records are available under P. pilosella Spencer, 1973 now recognized as a junior synonym of P. scotica (synonymy by von Tschirnhaus 2023 )). However, P. jurgensi can be distinguished from P. scotica by a yellow frons (part of frons slightly darker in P. scotica), a brown or black palpus (yellow in P. scotica), and a yellowish to greyish scutellum (brown in P. scotica). Both species have extremely small and weakly sclerotized genitalia, but the distiphallus of P. jurgensi has a cup-shaped or funnel-shaped distal end (Fig. 18 C) and the tubules have a darker and more sclerotized medial section (Fig. 18 D). In P. scotica, the phallus has one pair of very long, coiled tubules.	en	Marc, Stéphanie Boucher, Pollet, Marc (2025): New species and new records of leaf-miner flies (Diptera, Agromyzidae) from rainforest and inselberg at Mitaraka (French Guiana).
