The freshwater ichthyofauna of the Cubatão River basin was studied. This drainage belongs to the Atlantic rainforestbiome in Paraná state coastal region, southern Brazil. Considering fish collection data and extensive new collections, 41species were listed of the families Characidae, Erythrinidae, Crenuchidae, Curimatidae, Heptapteridae,Pseudopimelodidae, Callichthyidae, Trichomycteridae, Loricariidae, Gymnotidae, Cichlidae, Anablepidae, Poeciliidae,and Synbranchidae.

A key for species identification isprovided.
