Ctenopelmatinae is a cosmopolitan subfamily of ichneumonid parasitoid wasps.

They have a small tooth at the apex of the front tibia and usually do not have a fringe of setae along the clypeus.

Evidence from larval morphology and ecological traits separate these two groups, but adult specimens can be difficult to differentiate.

In the cooler parts of their range, ctenopelmatines can account for over 10% of all ichneumonids.

[1] Ctenopelmatinae are koinobiont endoparasitoids of Symphyta and, more rarely, Lepidoptera.
