Distribution Japan. Notes This species usually inhabits lotic environments of river ( Kawanabe et al. 2001 , Hosoya 2013 ). However, Sugiyama (1997) mentioned that this species often inhabits isolated ponds in the mountains in Tohoaku region. Our records of this species also include the isolated irrigation ponds as well as the rivers.
