Holotype male: ZMHB (high resolution images examined). Species known from Guyana and Brazil (not possible to determine the state). 

Bittacus geniculatus  is a unique species, and rarely collected. It is known only by the male holotype from Guyana and another specimen from Brazil, reported by Esben-Petersen (1927) and held in the Helsinki museum. This specimen is likely from one of the Amazonian Brazilian states. Willmann (1983) did not include B. geniculatus  in Thyridates  , mainly because the first fork of Rs in the forewing does not form a right angle. However, the species was transferred to Thyridates  by Collucci & Amorim (2000), who includes it in the “group angrensis  ”, based on its falcate forewing. Bittacus geniculatus  , can be easily distinguished from the remaining species based on its extremely long pterostigma, Rs 1+2 not forking, and by the elongated male epandrium.
