Syrphidae
Dideopsis aegrota (Fabricius)
SUMMARY
Dideopsis has by most authors been included in Asarkina, probably because of the anterior mesonotal pile collar in both genera. The only other striking similarity between the two genera is in the arrangement of the katespiternal pile. In head shape, wing markings, pilosity of meron and metaepisternum, pile of metacoxa, abdominal pattern, and particularly in the structure of the male genitalia there is no particular indication of relationship. Dideopsis, however, shows no strong affinities with other genera. No other genus in the Syrphini has a broad dark vitta covering 1/3 or more od the wing (from Vockeroth 1969).
