Remarks. Tanytarsus oyamai is probably one of the most common Tanytarsini in the southern part of the Sea of Japan basin; also frequent in North Korea - collected from half of the explored sites. The adult male is well-defined, thus only several illustrations are attached to show variations of the most important diagnostic structures (Fig. 6E–H).
