Material examined. 1♀, 12♂♂, NE China, Jilin Province, Meihekou City , 22.VII.2003 , Yang Zhong-Qi, cocoon mass in a gallery of M. raddei ; 6♀♀, id., but 18.VII.2004.

Hosts. Parasitoid of Cerambycidae ( Massicus raddei , Batocera horsfieldi (Hope)) .

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.
