Two new species of miniature tetras of the fish genus Priocharax from the Rio Juru á drainage, Acre, Brazil (Teleostei: Characiformes: Characidae)

We describe a remarkable sexual dimorphism of the pelvic girdle of Priocharax toledopizae in which the pelvic musculature is enlarged forming a pedicel for the fin in mature males. Most localities where these species were found suffer from significant degradation mainly due to litter accumul ation and suppression of the riparian forest, raising concerns about their conservation status.
