Genus Perineura

Perineura

There are thought to be ten species of Perineura globally, primarily distributed across the palaearctic region. In Britain and Ireland they are represented by one species.

The Perineura can be characterised within the Tenthredininae by the following features. The antennae are filiform and at least twice as long as the width of the head behind the eyes. The occipital carina is well developed around the entire occiput. The clypeus is deeply emarginate. In the forewing the anal cell has vein 2A+3A either touching vein 1A, or connected to 1A by a short, erect cross vein. The hindwing has two middle cells in the female and the male has a peripheral vein. The first abdominal tergite (propodeum is widely excised medially. The tarsal claws have a short inner tooth widely separated from the longer apical tooth.
