(Siluriformes: Callichthyidae) from the upper rio Paraná basin, Brazil
Luiz F. C. Tencatt, Marcelo R. Britto, and Carla S. Pavanelli
A new species of Corydoras is described from three tributaries of the rio IvaÃ* drainage, upper rio Paraná basin, Paraná State, Brazil. The new species can be distinguished from most of its congeners by the presence of three nasal pores. Other diagnostic features are the lower number of serrations in posterior margin of pectoral and dorsal spines and presence of four to six small black blotches along the midline of the flank. The possible mimetic relationship between the new species and Characidium heirmostigmata is discussed.
