Genus Potamocypris Brady, 1870

Superfamily: Cypridoidea Baird, 1845
Family: Cyprididae Baird, 1845
Subfamily: Cypridopsinae Kaufmann, 1900

Two species have been reported from Korea:

1. Potamocypris mastigophora (Methuen, 1910)

Additional figures in: Okubo 1976 (as Potamocypris producta); Okubo 2004 (as Potamocypris producta); Meisch 1985 (as Potamocypris producta), Kim & Min 1991 (as Potamocypris producta).

Habitat: Not mentioned for the Korean record. Elsewhere, eel culture ponds, pools of water (Okubo 1976; 2004), a river estuary (Ikeya & Hanai 1982), and rice fields (Petkovski 1964).

Mode of life: Nektobenthic (swimmer).

Reproductive mode: Mostly asexual. Males reported from South Africa (Sars 1924).

Known distribution: Jeju Island (Kim and Min 1991 as Potamocypris producta). Elsewhere, reported from Japan (Okubo 1976; Ikeya & Hanai 1982 both as Potamocypris producta), Africa (see references in Martens 1984); Macedonia (Petkovski 1964 as Potamocypris producta); France (Meisch et al. 1990 as Potamocypris producta); Israel (Lerner-Seggev 1968 as Potamocypris producta).
