DESCRIPTION. Head golden-grey pollinose except metallic shining frontal vitta and upper face, with bluish-greenish tinge; fronto-orbital plate golden pollinose. 3–4 long fronto-orbital setae, anterior interfrontal thinner and 1/3 as long as ocellar. Postocular setae weak and short. Palpus yellow. Antenna blackish, greyish dusted; arista pectinate on basal half of dorsal surface ( Fig. 6 ). Gena and parafacial greyish dusted.

Thorax black, grey pollinose. Scutum metallic subshining with greenish tinge. Acrostichals setulose in many irregular rows, intra-alars absent.

Legs. Femora yellow, greyish dusted or yellow; tibiae and tarsi of all legs yellow, darkened dorsally.

Abdomen black, grey pollinose, metallic subshining with greenish tinge. Tergite 5 about 1.5–2.0 times as long as tergite 4. Male genitalia large, as long as tergites 4+5. Epandrium elongate in dorsal (posterior) view ( Fig. 30 ); surstylus broad, rounded apically. Epandrium parallel-sided in lateral view ( Fig. 39 ); surstylus with oval median protuberance. Aedeagus with round- ed tip in lateral view ( Fig. 12 ). Gonite stout at base in lateral view, bifurcate apically, of complex shape, giving different images if slightly rotated ( Fig. 21 ).

NOTE. Wirth [1975] described E. murina from the territories of Iraq (holotype), Bulgaria, Iran, Romania, Turkey and Ukraine. The figures of surstyli dorsally were closer to E. flavip es, relatively broad basally and evenly tapering apically. Krivosheina [1983] described the species E. pseudomurina from Uzbekistan; surstyli of this species are broad almost to the tip and narrowed at the very apex. The same species was described by Hu & Yang [2001], who did not see the previous work, under the name of E. hejingensis Hu & Yang, 2001 . Beschovsky [2009] gave figures of surstyli the same as in E. pseudomurina and determined this species as E. murina . Przhiboro & Shadrin [2012] registered the same species in Russia under the name of E. murina . Krivosheina [2010] obviously had two morphological forms of E. pseudomurina . However we discovered specimens of Ephydra from Tajikistan, which surstyli are closer to the figures given for E. murina by Wirth [1975]. This prevented us from synonymizing pseudomurina , hejingensis and murina in the present work. We leave the solution to this question for the future, when the holotype of E. murina becomes available for study.
