It is a typical inhabitant of groundwater discharge at the surface, usually in small springs and seeps with a muddy substrate (Smith and Kamiya 2006; Smith 2011 ; Chang et al. 2012 ; this study). A total of three specimens were found at two localities (localities 2 and 33) in springs and seeps during our surveys. Currently, males are only known from two small Japanese islands (Smith and Kamiya 2006; Smith 2011 ); the specimens from Jeju Island are all females, but the three specimens collected are not sufficient in number to determine the reproductive mode of the population.
