Coenosia flavissima Hennig, 1961

Comments. A mysterious species. It was described by Hennig on the basis of only two males from Orenburg [51°46’N 55°06’E] in the European part of Russia ( Hennig 1961b: 554), and no specimens (both males and females) are known apart from the holotype and the paratype. The Orenburg region borders on Kazakhstan, and it can be assumed that this is a Central Asian species that is widely distributed south of Orenburg.

The holotype and the paratype are deposited in the Museum für Naturkunde, Humboldt-Universität zu Berlin, and they were studied by Pont & Werner (2006) and by Couri & Pont (2020). Coenosia flavissima resembles Coenosia ciliata Hennig, 1961 in the absence of basal scutellar setae but it is a very distinct species, easily recognized by its pale general colour and by the male terminalia (Fig. 478, plate XXIV in Hennig, 1961a).

Distribution. Palaearctic: Russia (SE).
