Species

Rhantus is a genus of beetle in family Dytiscidae. There are about 100 species distributed worldwide. They often live in pools and marshy habitat types. ^[1] Several species have colonized oceanic islands and become endemics. ^[2]

This genus is paraphyletic and will likely be revised, redefined, and split into several groups in future studies. ^[2] As a result of research published in 2017 by Balke et al., 17 species were moved from Rhantus to the genera Nartus , Meridiorhantus , Caperhantus , and Carabdytes . ^[3]
