Pristiphora compressa- Pristiphora abietina group
In the female the basal part of the sawsheath is parallel sided when viewed from above and the sides of the ninth tergite alongside the sawsheath are dulled by microsculpture between the punctures. This species is larger than the similar Pristiphora compressa. The ovipositor is no longer than the three basal tarsal segments and about as long as the middle tibia. The mesepisternum is black in compressa, but pale in the similar Pristiphora decipiens.
Pristiphora compressa larvae feed on spruces.
