Abstract

Tereancistrum paranaensis sp. n. is described from the gills of Schizodon borellii (Boulenger 1900) (Characiformes) from the upper Paraná river floodplain, Brazil. The new species is mainly characterized by morphology of copulatory complex, dorsal anchor with shaft recurved and pointed and arc-shaped dorsal bar. Tereancistrum parvus was described based on only one specimen and some characteristics were not observed. Now we provide an emendation to the diagnosis of this species.
