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]
