Abstract
Moenkhausia venerei is described from the rio Araguaia, Mato Grosso, Central Brazil. The new species differs from its con-geners, except M. collettii and M. copei, by the combination of the following characters: a longitudinal dark band extending from the tip of the snout to the base of caudal fin; a dark line along the base of the anal fin; and a conspicuous humeral spot.
Moenkhausia venerei is distinguished from M. collettii by having a wider and more conspicuous longitudinal dark band and from M. copei by the higher number of anal-fin rays. A discussion about the overall similarity and putative relationship with M. collettii, M. copei, Hemigrammus ulreyi, H. ataktos, and H. barrigonae is provided.
