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. 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.
Species
There are currently three described species in this genus:
- 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)
