Materials examined. JAPAN: KPM-NK 81832 , F, Osaka Pref., Takatsuki City, Kanmaki , 29. IV. 2011, M. Ito leg. ; KU, F (det. Momoi), Miyazaki Pref., Miyazaki, Yamashiro , 12. VII. 1964, K. Yasumatsu & T. Nishida leg. KOREA: SEHU, F (holotype), Keikido , Suigen, 30. X .

Distribution. Japan (Honshu*, Kyushu, Amamioshima Is., and Okinawajima Is.); Korea, the Philippines, and India

Bionomics. Host record: Grapholita molesta (Busck, 1916) ( Lepidoptera , Tortricidae ) ( Uchida, 1933b; Japan); Cotesia ruficrus (Haliday, 1834) ( Hymenoptera , Braconidae ) ( He, 1984; China); Egg sac of Araneida ( Araneae ) ( Broad et al., 2004; India). The above specimen deposited in KU is collected by sweeping in paddy field.

Remarks. This is the first record of this species from Honshu.
