Description . Frons width 0.33 mm ; ratio of frons width to eye width 2.5 (measured in dorsal view); orbit 0.16 times width of frons (frons including orbits) at midpoint; parafacial only slightly projecting, forming narrow ring (cheek) below eye; orbital setae particularly strong; 2 reclinate ors and 2 almost subequal inclinate ori; orbital setulae reclinate; first flagellomere (one missing) small to medium in size, covered with short pubescence; arista with short but dense pubescence; gena deep, conspicuously extended at rear; gena height at midpoint: 0.30 times maximum eye height; upper margin of clypeus thick and rounded; eye with a few short scattered hairs; one strong presutural and three postsutural dorsocentrals; acrostichal setulae in 4 irregular rows; 2 notopleural setae; postpronotum with one strong seta (only socket present) and 3 weaker ones; anepisternum with 1 strong seta on posterior margin a little above midpoint, with 2 smaller setae dorsally and 1 ventrally; fore and mid tibiae without lateral seta; stridulatory mechanism easily visible; wing length approximately 2.1 mm in male (wings bent). Last section of CuA1 1.3 times longer than penultimate. Colour . Frons and lower orbit yellow (lower ori on yellow); upper orbit brown to upper ori; both vt on brown; hind margin of eye brown on dorsal half; face partly brown below antenna and along facial carina, but yellow below; antenna mostly dark brown, except first flagellomere slightly paler basally (yellower on inner surface); palpus brown; clypeus shiny black. Mesonotum shining brown to margin of scutellum; scutellum largely bright yellow with brown patches laterally; basal scutellar setae on dark ground; postpronotum yellow with a central brown patch; notopleuron mostly yellow but dark brown at junction with anepisternum; anepisternum almost completely brown, only narrowly yellow posteriorly; katepisternum entirely brown; calypter dark brown including margin and fringe; halter white; legs dark brown with bright yellow knees. Abdominal tergites mostly brown, narrowly yellow laterally. Male genitalia . (phallus and phallapodeme missing). Posteroventral margin of epandrium without spine; anteroventral margin of epandrium with short hook-like projection (arrow, Fig. 51 ); postgonites long and widening apically ( Figs. 48–49 ); ejaculatory apodeme large, with strongly sclerotized bowl-shaped base and tube-like lateral projections ( Fig. 52 ); subepandrial sclerites (= bacilliform sclerites sensu Zlobin (2002)) fused, somewhat Xshaped with anterior arms much longer than posterior ones; these bearing one long seta ( Fig. 49 ).

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 .
