A new species of the parasitic-fly genus Tomosvaryella Aczél (Diptera, Pipunculidae) from Middle Asia

A new species, Tomosvaryella vadimi sp. n. (the minima group of species) similar to the Palaearctic T. minima Becker and T. aegyptium Kuznetzov, is described from the Central Kopet Dagh Mountains, Turkmenia, Middle Asia. The new species differs from the other species of the T. minima group in the bright metallic silvery pruinosity forming large dorsolateral spots on tergites III and IV and in large, moderately wide and elongate surstyli with angled inner and outer margins (see figure). The diagnostic characters of the new species, including the structure of the male genitalia, are illustrated and keyed.
