Bittacus angrensis: Souza Lopes & Mangabeira, 1942:336; Penny & Byers, 1979b:367; Machado et al., 2009:36; Machado, 2018. Thyridates angrensis: Willmann, 1983:50, Collucci & Amorim, 2000:7.

Bittacus angrensis, B. brunipennis and B. geniculatus form the group of Brazilian species with the apical region of the forewing falcate, referred to as “group angrensis ” by Collucci & Amorim (2000). The relationship between B. angrensis and B. brunipennis needs further investigation; they are very similar and males of the latter are still unknown.
