Genus Ctenochira Foerster, 1855

Remarks.

Ctenochira is the largest genus of the tribe Tryphonini occurring in the Holarctic and Oriental regions, comprising about 100 species ( Yu et al. 2016); the genus is best represented in the boreal and subarctic zones of the Holarctic region. The Nearctic fauna of the genus was revised by Townes and Townes (1949), and Palaearctic species were revised by Kasparyan ( Kasparyan 1973, 2013a etc.).

All species of Ctenochira are koinobiont ectoparasitoids of sawfly larvae of the family Tenthredinidae ( Hymenoptera : Symphyta ); the parasitoid female usually oviposits on exposed, living openly, larvae of the host.
