BERTACO, Vinicius A; JEREP, Fernando C  e  CARVALHO, Fernando R. New species of Moenkhausia Eigenmann (Ostariophysi: Characidae) from the upper rio Tocantins basin in Central Brazil. Neotrop. ichthyol. [online]. 2011, vol.9, n.1, pp. 57-63. ISSN 1679-6225.  http://dx.doi.org/10.1590/S1679-62252011000100003.

Moenkhausia dasalmas is described from the upper rio Tocantins basin, in the Chapada dos Veadeiros region, Goiás State, Central Brazil. The new species differs from all congeners by the presence of iii,9 rays in the dorsal fin. It can also be distinguished from its congeners by the presence of two humeral spots (first one vertically elongate and second one faint), by the number of branched anal-fin rays (17-19), lateral line scales (36-37), maxillary teeth (4-5), and a vertical dark spot in the caudal peduncle end.
