Type species: Hypsophrys unimaculatus Agassiz, 1859
Distinctive characters: In the first description of Hypsophrys, Agassiz (1859) only mentioned the similarity to Sparus auratus (Sparidae, a species from the Mediterranian). Regan (1905) gave distinctive characteristics for Hypsophrys (his section 7):
- The long pelvic fins reach to or over the beginning of the analis.
- The teeth of the outer row series in the upper jaw are moderate, regularly increasing in size anteriorly.
- In the lower jaw the 5 or 6 anterior teeth on each side are distinctly enlarged and differentiated from the smaller lateral teeth.
- Dorsal XVIII-XIX/ 10-11.
- Anal VII-VIII/ 7-9.
Species currently included:
|Hypsophrys nicaraguensis||C, P|
|C=CRC Catalogue, P=Note on phylogeny|
Distribution: Atlantic slope, from the San Juan drainage, including Lake Nicaragua, in Costa Rica and Nicaragua, to the Matina River drainage in Costa Rica (Bussing, 1998).
Behavior/ Ecology: Hypsophrys is the only Central American cichlid known to have non-adhesive eggs.
Further information: Molecular phylogenies indicate a potential close relationship to Neetroplus.
