Hypsophrys unimaculatus Agassiz 1859

Heros nicaraguensis Guenther 1864 .

Diagnosis. Hypsophrys unimaculatus is diagnosed as the only Hypsophrys with a centrally positioned spot on the flank (Figure 4; versus a bar or no marking) and caniniform teeth (versus spatulate).

Remarks. We agree with Kullander & Hartel (1997) that Hypsophrys nicaraguensis ( Guenther 1864) is a junior subjective synonym of Hypsophrys unimaculatus Agassiz 1859 but find their suggested suppression of the senior synonym in violation of ICZN Article 23. Therefore, this species should be recognized under its valid name Hypsophrys unimaculatus despite the relative familiarity of the junior synonym.
