Pristiphora carinata - Pristiphora carinata group
The stigma is always pale and the hind femur usually infuscated. The scutellum is glossy and virtually impunctate. The sawsheath is tapered and more or less triangular when viewed from above. The female is best determined by the characteristics of the saw. Males are best determined by the penis valve.
Pristiphora carinata larvae feed on bilberry and is therefore associated with moorlands and heaths.
