Comprehensive Description

[[ 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. (Lima et al., 2003; Eschmeyer’s Online Catalog of Fishes, 2006).

[[ Moenkhausia Eigenmann ZBK ]]

The genus Moenkhausia Eigenmann ZBK is a speciose characid genus, including at least 60 valid nominal species widely distributed throughout the Amazonas, Orinoco, São Francisco, Parnaíba , Paraguay and Doce river drainages, as well as in small coastal drainages of Guianas (Lima et al., 2003). The systematics of Moenkhausia ZBK is quite complex, particularly since there is no evidence corroborating the monophyly of the genus (Weitzman & Malabarba, 1998). Moenkhausia ZBK was first revised by Eigenmann (1917), which still constitutes the only all-inclusive review of the genus. Most papers on the systematic literature on Moenkhausia ZBK subsequent to Eigenmann’s revisions either involve the description of new species or taxonomic reviews of species occurring in restricted geographic areas of South America.

Fourteen Moenkhausia ZBK species have been reported from the rio Tocantins drainage (Lowe-McConnell, 1991; Géry , 1992, Costa, 1994; Lucena & Lucena, 1999; Lima et al., 2003), although only three have their type localities within the drainage.
