Coeloides bostrichorum Giraud: Yang, 1996, Parasitic wasps on bark beetles in China, 21.

Material studied. 2ΨΨ 1ɗ, CHINA, Heilongjiang, Daxing’an Mountain, Tuqiang, 8. ix. 1989, Sheng Mao­ling, ex. Ips subelongatus Motsch (CAFB); 2ΨΨ, CHINA, Heilongjiang, Heituqiang, 8. ix. 1989, Yang Zhong­qi (CAFB).

Diagnosis: This species is similar to Coeloides guizhouensis Yang, but can be separated from the latter by the key mentioned above. It has antennae with 30–38 segments; first flagellomere as long as the second one; second flagellomere moderately flared apically; third flagellomere normal, 1.3 times as long as the second one; notauli of mesoscutum shallow and wide anteriorly, and flatted posteriorly; veins 2­SR: SR1 of fore wing = 1: 2.5; first metasomal tergite with wide, smooth and deep grooves posterolaterally; second metasomal tergite with narrow and shallow longitudinal grooves laterally; and ovipositor sheath relatively long, 1.9 times as long as abdomen.
