Physocephala microvena species-group

This species-group combines some of the species which were variously placed by Camras (2001) in his Pseudophysocephala nigritarsis , Pseudophysocephala platycephala and Physocephala simplex species-groups. Members of this group cannot be defined by single char- acters but by a combination of characters as set out in Key 1. A reduced or absent radial-medial crossvein, and therefore either a reduced vena spuria or a vena spuria that lies very close to the radius R 4+5, is typical, however. Almost always there is no hyaline wing membrane be- tween the vena spuria and radius R 4+5 and the aristomeres are elongated, with the apical aristomere usually tower- ing over the basal aristomere. The group contains some very difficult species, several of which can readily be confused with members from other species-groups, and more material is necessary in order to understand the full variability of the species. All members of this group are restricted to the Afrotropical Region.
