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.

Biology: The known hosts are uniformly from the family Scolytidae (Coleoptera) : Blastophagus minor Hartig ( Mills, 1983) , Blastophagus piniperda Linnaeus ( Mills, 1983) , Carphoborus minimus F. ( Mills, 1983), Cryphalus piceae Ratzeberg ( Haeselbarth, 1967; Hedqvist, 1998; Mills, 1983; Tobias, 1976; Tobias, 1986), Ips amitinus Eichhoff ( Mills, 1983) , Ips cembrae (Heer) ( Mills, 1983; Watanabe, 1958), Ips duplicatus Reitter ( Mills, 1983; Tobias, 1986; Tobias, 1976), Ips sexdentatus Boerner ( Mills, 1983) , Ips subelongatus Matschsky ( Tobias, 1976; Tobias, 1986), Ips typographus L.(Capek, 1972; Eck, 1990; Faccoli, 2000; Faccoli, 2001ab; Faccoli, 2002; Fahringer, 1926; Feicht, 2004; Haeselbarth, 1967; Hedqvist, 1998; Hougardy & Gregoire, 2003; Krger & Mills, 1990; Lukas, 1980; Mills, 1986; Mills, 1983; Tobias, 1986; Tobias, 1976; Watanabe, 1958), Pityogenes chalcographus L.

Distribution: China (Heilongjiang province) and Europe.
