In China , cocoon of a sawfly, Cephalcia lariciphila (Wachtl, 1898) ( Pamphiliidae ) was recorded as host ( Sun et al. , 2019 ). Fig. 2. Ctenopelma pineatus Sheng, Sun & Li, 2019 (A–D: KPM-NK 84787, female; E: KPM-NK 84788, male) ― A: lateral habitus; B, E: head, frontal view; C: propodeum, dorso-lateral view; D: areolet. 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 .
