Etymology: venerei: Named for Dr. Paulo César Venere, collector of this new species and for his contributions to the knowledge of the Rio Araguaia ichthyofauna.
Eponymy: Dr William J Moenkhaus (1871–1947) was an American geneticist and ichthyologist who became Professor of Physiology at Indiana University Medical School (1904–1941), where he was Eigenmann’s colleague. [...] Dr Paulo César Venere is a Brazilian biologist and ichthyologist who graduated with a bachelor’s degree (1986), a master’s (1991) and defended his doctorate in genetics and evolution (1998), all from the Federal University of São Carlos.

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 11; Raios anais : 21 - 28; Vértebras: 30. Moenkhausia venerei is distinguished from all congeners, except M. collettii and M. copei, by having a conspicuous dark line along the base of the anal fin (vs. dark line absent) and by having a well-marked longitudinal dark stripe extending from the tip of the snout to the base of caudal fin (vs. dark stripe absent). It differs from M. copei by 19-24 branched anal-fin rays (vs. 15-17 in M. copei); and from M. collettii by the possession of more conspicuous and wider longitudinal lateral dark stripe, about a scale deep along the flank (vs. stripe narrow, more restricted to the posterior half of the horizontal septum). Out of the limits of the genus, M. venerei shares similarities with Hemigrammus ulrey, H. barrigonae, and H. ataktos.
Body shape (shape guide): elongated.
