Physocephala caenoneura species-group

Species belonging to this group were previously included together with other species in the Pseudophysocephala nigritarsis species-group of Camras (2001). This caused some confusion because these species may have both a distinct vena spuria which is well separated from radius R 4+5, and short apical abdominal segments, thus poten- tially appearing to fall within his Pseudophysocephala vitripennis and Pseudophysocephala platycephala species-groups respectively.

Females of the caenoneura species-group are easily recognised by the normally developed, usually ad- pressed theca and short tergites 5 and 6. From outside the caenoneura group, only P. microvena and P. pseudomicrovena share this combination of characters but are easily recognised as belonging to the Physocephala microvena species-group by the lack of a vena spuria in cell r 4+5, and typically also by the reduced or absent radi- al-medial crossvein. Males of caenoneura group can be more difficult to assign, however, the elongated basal ari- stomere and less modified wing venation being the only characters which reliably distinguish them from males of the microvena species-group. All members of this group are restricted to the Afrotropical Region.
