Potamarius is a genus of sea catfishes. The three species in this genus exclusively inhabit fresh water in southern Mexico and Guatemala. The individual species have relatively small ranges.[1] The highly endangered Paragenidens grandoculis of Brazil was long classified in Potamarius, but a 2019 study has found it to belong in its own genus.[2]
Species
There are currently three described species in this genus:[1][2]
- Potamarius izabalensis C. L. Hubbs & R. R. Miller, 1960
- Potamarius nelsoni (Evermann & Goldsborough, 1902) (Lacandon sea-catfish)
- Potamarius usumacintae Betancur-R. & Willink, 2007 (Usumacinta sea-catfish)
