Hygrobates (Hygrobates) calliger Piersig, 1896

Records from Korea: Gangwon Province – “ Hygrobates heteropalpis “ Chung and Kim (1991) .

Habitat: Rhitrobiont.

Remarks: Matsumoto et al. (2005) synonymised with “a little doubt” Hygrobates heteropalpis Imamura, 1954 with H. calliger . However, they mentioned that the P­2 projection of the European specimens of H. calliger tends to be broader than that of either H. calliger or H. heteropalpis from Japan. The latter feature could be a good reason for reanimating H. heteropalpis . Application of molecular techniques could be helpful for understanding the taxonomic position of the populations from Japan and Korea assigned to H. calliger .

Distribution: Palaearctic.
