The species is known only by the female holotype, which is very similar to specimens of  B. angrensis. This similarity was noted by Collucci & Amorim (2000), who mentioned the color of the pterostigma as the main character to distinguish these two species. This character however, does not seem very strong, since it shows some plasticity in other species of  Bittacus, suggesting that  B. brunipennismight be a synonym of  B. angrensis. Because the species was described from a female, the identification of  B. brunipennisremains uncertain mainly because the shape of the male epandrium is one of the most important characters to distinguish  Bittacusspecies. The collection of male specimens close to the type locality, Campos do Jordão State Park ( São Paulo), will be needed to solve this question. 2029165302 [151,901,1807,1832] Brazil Sao Paulo 3 306 1 Sao Paulo holotype
