[[Hypsophrys Agassiz 1859]] Results Examination of the holotypes of Neetroplus nematopus and Hypsophrys nicaraguensis show that these species share a number of unique derived features (Figure 1-2; see Table 1 for counts and measurements). These features include possession of a single supraneural (Figure 3), a strongly rounded snout profile, and a small and slightly subterminal mouth. On the basis of these shared apomorphic features, and a lack of autapomorphic features attributable to either genus, we place Neetroplus Günther 1867 in synonymy with Hypsophrys Agassiz 1859. Therefore, Neetroplus nematopus Günther 1867 is henceforth Hypsophrys nematopus (Gùnther 1867).
