Genus Oestropsyche Brauer, 1868

Oestropsyche Brauer, 1868: 265 [Type species: Oestropsyche palingenia Brauer, 1868: 266 [= Oestropsyche vitrina Hagen, 1859 ] (by monotypy)]; Ulmer, 1907 (redescription).

Diagnosis. This genus can be distinguished from other Macronematinae genera by having two head setal warts raised anteriorly on vertex ( Fig. 182 ). Forewing discoidal cell absent. Median cell longer and broader in males than in females. Thorax without markings. Tibia and tarsal segments of legs, dilated.

Remarks. Fischer (1963) initially placed this genus in the tribe Macronematini , despite the absence of mouthparts, whereas Barnard (1980) placed it in the tribe Polymorphanisini based on both larval characters and the absence of adult mouthparts ( Ulmer, 1951).
