Abstract

Hisonotus bocaiuva, new species, is described from the rio Sao Francisco basin, municipality of Bocaniva, Minas Gerais State, Brazil. It is distinguished from other members of the Otothyrinae by the following characters: a conspicuous tuft of enlarged odontodes on the posterior tip of parieto-supraoccipital; the presence of a rostral plate with posterior notch articulated with mesethmoid; the snout completely covered by odontodes; the abdomen partially covered by plates; the number of lateral median plates; the absence of adipose fin; and by morphometric characters. The new species is additionally distinguished by having three vertical dark bands on the caudal fin and the absence of broader light stripes on the dorsolateral surface of the head. (AU)
