Distribution. Japan (Honshu); China.

Bionomics. Unknown in Japan. In China, cocoon of a sawfly, Cephalcia lariciphila (Wachtl, 1898) ( Pamphiliidae ) was recorded as host ( Sun et al., 2019).

Remarks. This is the first record of this species from Japan. This species resembles Ct. lucifer but can be distinguished by the following combination of characters: area superomedia and area petiolaris of propodeum more or less confluent (separated by carina in Ct. lucifer ); anterior portion of median longitudinal carina of propodeum obliterated (complete and strong in Ct. lucifer ); face black, lower lateral portion with large white spots (entirely yellowish brown in Ct. lucifer ); frons and vertex entirely black (with lateral yellowish brown spots in Ct. lucifer ); hind coxa, trochanter, and femur entirely black (brown to dark brown in Ct. lucifer ); T III red (T II to T IV red in Ct. lucifer ) ( Sun et al., 2019).

A synonym of Ct. lucifer , Ct. tokioense Uchida, 1930 (type locality: Tokyo), shares with the character states of Ct. lucifer sensu Sun et al. (2019) . Thus both Ct. lucifer and Ct. rufofasciatum are distributed in Japan.
