BIONOMICS.The specimens were collected on the banks of cold streams near thermal springs (Fig. 12).

REMARKS. Coryphium miyamorii was described based on numerous specimens from Hokkaido and Honshu [Watanabe, 1988]. Zerche [1990] studied only the holotype and did not provided figures of mouthparts and apical abdominal sclerites, while Watanabe [1988, 1990] published figures of the aedeagus in two projections and the ventral view of the median lobe. Habitus as in Fig. 7. In the present paper, we present the following figures: aedeagus with somewhat deformed basal portion (Fig. 37), labrum (Fig. 31), maxillary palpus (Fig. 32), labium and mentum (Fig. 33), male sternite IX (Fig. 34), male tergite VIII (Fig. 35) and male sternite VIII (Fig. 36). This species is recorded for Russia and Kunashir for the first time.
