New species of parasitic copepods of the Genus Acusicola (Poecilostomatoida: Ergasilidae) from gill filaments of coastal and freshwater Brazilian fishes, and proposition of Acusicola rogeri n. sp. for A. tenax sensu Cressey & Collette (1970)

Abstract

Four new species of Acusicola are described based on adult females found on gill filaments of several species of coastal and freshwater fishes caught in Brazilian basins. The distribution area of the genus in Brazil is significantly enlarged, since until now the previous Brazilian species had been known only from Amazonian fishes. The specimens identified as Acusicula tenax by Cressey and Collette (1970) are considered representatives of a new species, A. rogeri. A key for identification of the species of Acusicola is provided.
