Material examined. Kaesŏng , 16 July 1981, 1 male ; Phjŏngjang , 13 June 1981, 7 males , 18 July 1981, 1 male ; Sariwŏn , 18 June 1981, 3 males ; Sokam , 8 July 1981, 2 males; leg. W. Krzemiński.

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 ).
