Description of a new Batrochoglanis species (Siluriformes, Pseudopimelodidae) from the rio Paraguai basin, State of Mato Grosso, Brazil

Abstract

A new Batrochoglanis species, B. melanurus, is described from the corrego Cancela, affluent of rio Cuiabá, rio Paraguai basin, State of Mato Grosso, Brazil. The coloration pattern of the caudal fin, completely dark-brown, distinguishes this species from its congeners. Some additional morphometrical characters, such as head depth, pectoral-girdle width, adipose-fin base length and pelvic-fin length also separate this species from the others, except B. villosus (Eigenmann).
