Molecular analyses of the phylogenetic relationships of Central American cichlids revealed a close relationship of Hypsophrys nicaraguensis and Neetroplus nematopus (Hulsey et al. 2004). These two species from in fact a monophyletic group. Thus, Neetroplus Günther, 1867 may be considered as a junior synonym of Hypsophrys Agassiz, 1859.

Hypsophrys nicaraguensis and Neetroplus nematopus indeed share several characteristics. Both species have a unique head morphology with a rounded profile and a subterminal mouth. Furthermore, both species have a distinct black color pattern in the middle of the body (a big blotch in H. nicaraguensis and a vertical band in N. nematopus. Both species breed in crevices.
