Pristiphora albilabris - Pristiphora carinata group

The mesopleura is dulled by microsculpture. The labrum, pronotum, tegulae, coxae, femora and bases of tibiae are reddish-yellow. The female is best determined by the characteristics of the saw. The sawsheath is triangular when viewed from above. Males are best determined by the penis valve.

Pristiphora albilabris larvae feed on downy birch and may also feed on other birches.
