Diagnosis. Lower facial margin not protruded in lateral view; prementum short, about 3 times as long as wide; gena narrower than 1/5 of eye height in female, usually narrower than in C. communis; surstylus swollen at apex in dorsal and lateral views.
Redescription. Body length. 6.3–8.4 mm.
Male. Vertex 0.23–0.27 of head width; inner vertical seta strong, 0.6–0.9 of eye height; outer vertical seta present, about 0.4 times as long as inner vertical seta; frontal vitta widened anteriorly, 1.0–1.3 times as wide as fronto-orbital plate at middle; parafacial 0.8–1.0 times as wide as 1 st flagellomere at mid-height; facial ridge with several setae on lower 2/5–4/7; lower facial margin not protruded in lateral view; gena 1/7–1/5 of eye height; 1 st flagellomere 2.8–4.5 times as long as pedicel, about 3.5 times as long as wide; arista thickened on about basal 0.15. Palpus 0.7–0.9 times as long as 1 st flagellomere; prementum about 3 times as long as wide. Postabdomen. Surstylus slender, swollen at apex, with many setae in apical half in lateral view, swollen at middle and apex and curved inward in apical 1/ 3 in dorsal view; cercus nearly triangular in dorsal view; postgonite nearly rectangular and tapering apically; distiphallus narrowly trapezoidal in dorsal view.
Female. Differs from male as follows: vertex 0.26–0.31 of head width; gena 1/6–1/5 of eye height.
Distribution. China (Guangdong, Guizhou, Sichuan, Shaanxi, Yunnan), Taiwan, Japan (Hokkaido, Honshu, Shikoku, Kyushu), southern Far East Russia.
Host. One specimen was reared from a Pachyprotasis Hartig (Hymenoptera: Tenthredinidae) species in Japan (Mesnil 1962).
Remarks. O’Hara et al. (2009) suggested that the previous records of C. flavipalpis from China might be misidentifications and that the species was unlikely to occur in China. Based on the above examined material, we confirm that C. flavipalpis is widely distributed in China and East Asia, and record it for the first time from Taiwan.
