Ctenopelma pineatus Sheng, Sun & Li, 2019 , in Sun et al. (2019): 16.

Description. See Sun et al. (2019).

Materials examined. JAPAN: KPM-NK 84787 , F, Nagano Pref., Chino City, Kitayama, Mugikusa-toge , 20. VI. 2007, H. Katahira leg. ; KPM-NK 84788 , M, Aomori Pref., Mt. Hakkoda , 8. VII. 1958 , R. Ishikawa leg.

Distribution. Japan (Honshu); China.

Bionomics. Unknown in Japan. In China, two sawflies, Acantholyda posticalis (Matsumura, 1912) and Cephalcia lariciphila (Wachtl, 1898) (both Pamphiliidae ) were recorded as host ( Sun et al., 2019).

Remarks. This is the first record of this species from Japan. This species (especially the males) appears similar to Ct. boreale , but can be easily distinguished by the simple tarsal claw (pectinate in Ct. boreale ).
