[[ Moenkhausia Eigenmann ^ZBK ]]

The genus Moenkhausia ^ZBK was erected by Eigenmann (1903) and is currently defined by the presence of premaxillary teeth in two parallel rows, five or more teeth in the inner premaxillary tooth row, a completely pored lateral line, and scaled caudal-fin lobes (see Eigenmann, 1917). Presently, the genus comprises 63 valid species of small characids largely distributed in South America drainages of the Río Orinoco, Rio Amazonas, Rio Tocantins-Araguaia, Rio Paraguay, Rio Uruguay and Rio Doce.
