Espírito Santo: Linhares, Reserva Biológica Sooretama , 23 m a.s.l., 18°58'02.7''S 40°08'06.8''W, 1 male, 24– 27.iii.2002, Malaise trap (Bosque-5), C.O. Azevedo et al. ( BIOTA-FAPESP) . Bahia: Mata de São João, Reserva de Sapiranga , 12°33'36.4''S 38°02'57.2''W, 2 males, 19–22.vii.200, Malaise trap (Bosque-3), M.T. Tavares et al. ( BIOTA-FAPESP) . Sergipe: Sta Luzia do Itanhy Castro , 11°22'31.2''S 37°24'50.9''W, 1 male, 29.vii–01.viii.2001, Malaise trap (Bosque-5), M.T. Tavares et al. ( BIOTA-FAPESP) ( MZUSP, ZMBN) .

Diagnostic characters: The male can be separated from all other members of the genus by having bare wing membrane and squama with few setae; acrostichals starting in front, anterior ones hair-like, posterior ones scalpellate; virga well developed; anal point nearly parallel-sided with blunt apex, with weak lateral setae; and inferior volsella consisting of triangular, pointed lobe. The pupa differs from that of other known species by having antennal sheath with pearl row and thorn-like anal macrosetae less than half as long as the male gonopodal sheaths. The larva has mentum with 5 lateral teeth and antennal blade subequal in length to flagellum.

Remarks: This species is rather variable in the shape of the inferior volsella, with some specimens having an extremely long volsella, almost reaching the tip of gonostylus; the anal point also varies in shape and size, but is always parallel-sided with weak, lateral setae.

Distribution: The species occurs all along the Brazilian Atlantic Forest, from Santa Catarina in the south north up to Sergipe on the northeastern coast.
