Mesosoma brownish yellow; lateral portion of pronotum, lateral marginal area of mesoscutum, lateral portion of scutellum, markings on mesopleuron and ventral half of metapleuron yellow. Legs brownish yellow; fore coxa and anterior half of mid coxa yellow; hind tarsus whitish yellow. Wings hyaline; vein C and pterostigma of fore wing brownish yellow, other veins brown. Metasoma brownish yellow.

Distribution. Japan (Hokkaido, Honshu, Shikoku, Kyushu), Russia (Primorye, Sakhalin).
Remarks. This species is considered to be closely related to gansuana, nodai, pallescens, virgata, yakushimensis and yamatoensis in having the overhang, the strip of minutely papillate cuticle and the membranous pad on the mesal surface of the paramere and the teeth on the ventro-apical corner of digitus. Thus, these seven species belong to the virgata group.
This is the first record of comitor from Japan.
