Still,  Hylomyrma villemantaeis very similar to  H. peetersiand  H. margaridae. All three species have a strongly convex petiole, with indistinguishable petiolar peduncle and node, and the body mainly covered with regular and longitudinal striae. Even so,  H. villemantaecan be easily distinguished from both (characteristic in parenthesis) in the striae on the head dorsum with smooth crests (vs. with punctuated crests), the mesosoma with few elliptical and concentric striae (vs. longitudinally striate), the longer propodeal spine (vs. shorter), the unarmed mesoventral surface of petiole (vs. armed), and the smooth dorsum of postpetiole and gaster (vs. with longitudinal striae). All three species are allopatric;  H. villemantaeis recorded from Brazil(BA) ( Fig. 86), whereas  H. peetersiand  H. margaridaeoccur in relatively close areas in northern South America (French Guiana, Guyana, and Venezuela) ( Fig. 89).   Distribution.This species occurs in Ibicuí and Itororó, Bahia, Brazil( Fig. 86).  Natural history.The biology of this species remains unknown. Typespecimens were collected in leaf-litter with winkler extractors, at elevations between 951 and 1070 min the region known as “ Serradas Piabas”, a fragment of Atlantic forest in the Brazilian state of Bahia.   Additional material examined( 1 worker):   BRAZIL: BA[ Bahia]:Itororó, [área] C, 08.08.00, 14.57.31S, 40.02.33W, Santos J.R.M.dos (1W) (MZHY199) [ MZSP]. 3392794582 2017-05-12 Lacau S. & Neves M.
