Distribution. China (Anhui, Beijing, Hainan, Hubei, Jilin, Sichuan, Taiwan, Zhejiang), India, Japan, Korea, Laos, Thailand.

Remarks. Body length ♀ / ♂ 13.7–15.5/ 14.1–18.2 mm. Length of cocoon mass 45.2 mm, diameter of cocoon mass 15.5 mm. Euurobracon yokahamae is a gregarious parasitoid, with two observed cocoon masses containing 6 and 13 individuals, and within a cocoon mass they are nearly all of the same gender. Judging from the size of the cocoon mass, this species likely parasitises mature larva.
