Clithon ruginosus (Récluz, 1841)
Distribution:
The Récluz locality of Hawaii is obviously in error and although von Martens (1879) reported the species occurring in Samoa, Fiji, and New Caledonia, the specimens we examined were from Malaysia, the Philippines, Taiwan, and Kadena, Japan.
Habitat:
Fresh water in small streams and rivers on algae covered stones and on vegetation stalks.
