Comments. A new record for Russia.

Coenosia nevadensis was described from southern Spain (Granada) in 1970 by L. Lyneborg. Lyneborg noted that this species is very similar to Coenosia sexpustulata Rondani, 1866 and he could not find any differences between them except for some characters of the male terminalia (Figs. 27, 28 in Lyneborg 1970). Later Pont (in Pont et al. 2005) described Coenosia brevicauda from one male and three females from Armenia. According to this description, Coenosia brevicauda is also very similar to the European Coenosia sexpustulata and can be separated from it by chaetotaxy of the hind femora and by the cercal plate. The description of Coenosia brevicauda does not include a figure of the terminalia but illustrates the lateral view of the abdomen (Fig. 4 in Pont et al., 2005). I studied specimens from Turkey and Russia (Caucasus) named as “ brevicauda ” and dissected the male terminalia (Figs 5 A–C). The terminalia of the Turkish specimens are fully consistent with Lyneborg’s illustrations, and the morphology agrees with the description of both Coenosia nevadensis and Coenosia brevicauda . I therefore conclude that Coenosia brevicauda Pont in Pont, Werner & Kachvoryan 2005 is a new junior synonym of Coenosia nevadensis Lyneborg, 1970 .

Coenosia nevadensis is very close to Coenosia sexpustulata, with a particularly plump male abdomen (Fig. 4 A). I was also unable to find any morphological differences between these species except in the male terminalia (Figs 5 A, C; Fig. 540, plate XXIX in Hennig 1961b). In addition, sternite 5 of Coenosia nevadensis has four strong setae at the tip of each lobe (Fig. 5 C) which was not noted in the descriptions of the two holotypes. Females of Coenosia nevadensis are very similar not only to Coenosia sexpustulata, but also to Coenosia octosignata Rondani, 1866 . The females of Coenosia nevadensis, Coenosia sexpustulata and Coenosia octosignata appear to be difficult to distinguish.

Distribution. Palaearctic: Armenia, Greece, Morocco, Russia (SE), Serbia, Spain, Turkey.
