Actinopterygii (ray-finned fishes) > Characiformes
(Characins) > Distichodontidae
Etymology: Neolebias: Greek, neos = new + Greek, lebias, ou = a kind of small fish (Ref. 45335).
This species is placed in the genus Nannaethiops in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697) following Géry & Zarske (2003: Ref. 77044) who consider the genus Neolebias Steindachner, 1984 as a junior synonym of Nannaethiops Günther, 1872. However, the two genera are most likely distinct (Sonnenberg, pers. comm. 05/2011). Please send references, or more studies are needed.
