Material examined. Hokkaido, 2 ♂, Kushiro, 16. v. 1988, leg. M. Iwasa ( OUAVM) .

Diagnosis. Cleigastra tibiella (Zetterstedt) can be recognized by the following characteristics: frons black; face, parafacial, and genae pale yellow with silvery microtrichose; postpedicel black with acute upper corner ( Fig. 15 View FIGURES 15–20 ); thorax and abdominal tergites grey dusted ( Fig. 15 View FIGURES 15–20 ); katepisternum with 3 setae ( Fig. 16 View FIGURES 15–20 ); fore femora blackish with 7-10 distinct av setae ( Fig. 17 View FIGURES 15–20 ); male sternite V bilobate posteriorly ( Fig. 18 View FIGURES 15–20 ); male surstyli filiform, apically rounded, arched close to each other at the tips ( Figs 19, 20 View FIGURES 15–20 ).

Body length (♂). 4.7–4.8 mm.

Distribution. Europe, Japan (Hokkaido), Russia (Kamchatka Kray, Kranoyarsk Kray, Leningrad Oblast and St.- Petersburg, Magadan Oblast, Moscow Oblast, Sakhalin Oblast, Tumen’ Oblast) ( Ozerov & Krivosheina, 2015). New to Japan.

Remarks. This species is very similar to C. puberula (Becker) in the structure of male fore femora and surstyli, but can be easily distinguished from it by the blackish fore femora.
