Species also known from: Paraná (new record), Rio de Janeiro, São Paulo (new record) (Fig. 12 a). 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).

200587D4FFBD2855FF4DFE9B2D9AA2E4.taxon	discussion	Comments. Based on its maculated wings, Bittacus cruzi sp. n. fits in the “ group chilensis ” as proposed by Collucci & Amorim (2000). Within the group, it shares with B. ferreirai and B. maculosus the number of costal crossveins in the wings (one). However, the shape of the male epandrium suggests a closer relationship between Bittacus cruzi and B. boraceiensis; both species present a medial actiniform process, but the subapical processes of B. boraceiensis are absent in the new species, easily separating them.	en	Machado, Renato Jose Pires, Mendes, Diego Matheus De Mello, Rafael, José Albertino (2018): The genus Bittacus Latreille (Insecta: Mecoptera) in Brazil: key to species, distribution maps, new synonym, and three new species.

200587D4FFBF2857FF4DFA442AEDA4B4.taxon	discussion	Comments. Because of the maculated wings, Bittacus ferreirai sp. n. is another species that would fit in the “ group chilensis ” as proposed by Collucci & Amorim (2000). Within the group, B. ferreirai seems to be closer to B. blancheti; the male epandrium of both species does not present any actiniform process and the internal margins of the lobes converge towards the apex. However, they can be easily separated by the general shape and color of the wings. Based on the wing shape and body color, B. ferreirai sp. n. is similar to B. cruzi sp. n. (1 costal crossvein, Rs 1 + 2 not forked in the hind wing and legs and antennae not alternating between pale and dark bands), but their head color, mostly pale in B. ferreirai, mostly dark brown in B. cruzi, and male genitalia with internal margin of epandrium converging in B. ferreirai and diverging posteriorly in B. cruzi, easily distinguish them.	en	Machado, Renato Jose Pires, Mendes, Diego Matheus De Mello, Rafael, José Albertino (2018): The genus Bittacus Latreille (Insecta: Mecoptera) in Brazil: key to species, distribution maps, new synonym, and three new species.

The shape of the subapical lobes in the inner margin of the male epandrium of B. varzeanus is somewhat similar to B. angrensis; however, the new species lacks the typical falcate apex of the wings of B. angrensis. The general shape of the wings is similar to that of B. flavescens, but the shape of the male epandrium easily distinguishes them. The medial excavation on the posterior margin of the male epandrium of B. varzeanus sp. n. is unique within the South American species of Bittacus.	en	Machado, Renato Jose Pires, Mendes, Diego Matheus De Mello, Rafael, José Albertino (2018): The genus Bittacus Latreille (Insecta: Mecoptera) in Brazil: key to species, distribution maps, new synonym, and three new species.
