Abstract

The taxonomy of the potamid genus Hainanpotamon Dai, 1995, from Vietnam, Laos, Hainan Island (China) and, purportedly, Okinawa Island (Japan) is reviewed. The type species, Potamon (Potamon) orientale (Parisi, 1916), is redescribed and a lectotype designated. In addition, three new species are described. The poorly known species Potamon (Geothelphusa) globosum Parisi, 1916, is assigned to Hainanpotamon and its taxonomy clarified, with a lectotype designated. A key to the nine species of Hainanpotamon is provided.
