Absonemobius vincenti , n. sp. , A–D, male holotype, E–G, male paratype MNHN-EO-ENSIF4187: A, male habitus; B, face; C, head, pronotum and abdomen, lateral; D, leg III, outer side; E–G, male genitalia, dorsal (E), ventral (F), lateral (G). Scales 1 mm. Abbreviations: see Material and methods. Arrows show the deep notch on the left of pseudepiphallic sclerite. Distribution. Lesser Antilles, St. Vincent . Etymology. Species named after its origin. Diagnosis. Within the genus, species very similar to Absonemobius septentrion , n. sp. from which it can be separated by its smaller size, darker pattern of coloration and male genitalia (asymmetrical, as in Absonemobius septentrion , n. sp. , but pseudepiphallic sclerite more strongly asymmetrical, pseudepiphallic process longer and more narrow, with a deep V-shaped notch on distal margin, pseudepiphallic parameres located farther from pseudepiphallic apical margin because of increased length of pseudepiphallic process). A. vincenti n. sp. is also close to A. lucensis n. sp. from which it can be separated by details in coloration and male genitalia (see below). Description. In addition to the characters of the genus ( Desutter-Grandcolas 1993 ): Size very small (see measurements). Coloration. Fig. 2 A–D. Face ( Fig. 2 B) dark brown, somewhat marked with yellowish brown along inner margin of eyes; eyes black and golden. Scape and antennae very light brown. Maxillary palpi ( Fig. 2 C) dirty yellow, joint 5 yellowish brown ( Fig. 2 B). DD light brown with diffuse darker spots; margins light brown ( Fig. 2 A). LL and abdomen, including subgenital plate, black brown ( Fig. 2 C). Cerci light brown. Legs light brown, upper part of FIII and knees darker. Male genitalia. Fig. 2 E–G. Pseudepiphallic median lobes fused into a very long and flat process, but wellseparated distally by a deep and narrow V-shaped notch ( contra A. lucensis n. sp. , A. septentrion n. sp. , A. alatus ); in lateral view ( Fig. 2 G), pseudepiphallic process distinctly raised apically, and quite narrow compared to A. septentrion n. sp. and A. lucensis n. sp. and (compare with Fig. 1 G and 3G). Pseudepiphallic sclerite asymmetrical, as in A. septentrion n. sp. , A. lucensis n. sp. and A. alatus , but left part of pseudepiphallic sclerite much more distal than in other species; anterior margin also more sclerotized. Pseudepiphallic parameres as in A. septentrion n. sp. but farther from pseudepiphallic distal margin because of greater length of pseudepiphallic process. Epi-ectophallic invagination, ectophallic fold, ectophallic apodemes, endophallic cavity and endophallic sclerite as in A. septentrion n. sp. Female. Subgenital plate transverse, distal margin bisinuate; entirely black brown. Penultimate sternite black brown. Ovipositor only slightly shorter than TIII. Female genitalia. Not examined. Measurements (in mm).
