Worker ( Fig. 76A–C) Diagnosis.Regular and longitudinal striae on head dorsum diverge towards posterior margin, interspaces between striae smooth, striae crest smooth; mesosoma covered with concentric and elliptical, regular and thick striae; longitudinal striae on lateral of pronotum and mesepisternum in part continuing transversely on propodeum and in part continuing on propodeal spine; transverse carina inconspicuous; propodeal spine midsized; dorsal margin of petiole continuous, strongly convex, mesoventral surface unarmed; petiole, postpetiole, subpostpetiolar process, profemur posterior surface, protibia extensor surface and tergum of first gastral segment smooth; subpostpetiolar process weak, convex.
QUEEN Unknown. MALE Unknown.
Etymology.This species was named in honor of Dr. Claire Villemant, a French entomologist, curator of the HymenopteraCollection at Muséum National d’Histoire Naturelle de Paris.
Comments.The diagnostic characters of this species are sufficient to easily distinguish it from most of its congeners. 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.
