Pristiphora decipiens - Pristiphora abietina group
In the female, the head is mostly pale above. In dorsal view, the sawsheath has distinct scopa posteriorly. In lateral view, the posterior margin of the sawsheath is truncate. Claws have a large subapical tooth. Males should be determined by the penis valve, but in both sexes, the mesepisternum is pale in Pristiphora decipiens (black in the similar Pristiphora compressa).
Pristiphora decipiens larvae feed on spruces.
