DESCRIPTION. Head whitish-grey (alandica) or grey ( macellaria ) pollinose except metallic shining frontal vitta and upper face, with bluish-greenish tinge; fronto-orbital plate grey pollinose. 3 long fronto-orbital setae, anterior interfrontal thin and about 1/3 of ocellar. Postocular setae thin and short. Palpus yellow-grey to dark grey. Antenna black, brown dusted; arista pectinate on dorsal surface. Gena and parafacial whitish-grey or greyish-golden dusted.

Thorax black, densely whitish-grey or grey pollinose. Scutum whitish-grey pollinose or metallic subshining. Acrostichals setulose in many irregular rows, intra-alars absent.

Legs black, densely greyish pollinose; tarsi yellowish.

Abdomen black, densely whitish or grey pollinose, subshining with greenish tinge or without metallic tinge. Tergite 5 about 1.3–1.5 as long as tergite 4. Male genitalia large, as long as tergites 4+5. Epandrium elongate-oval in dorsal (posterior) view ( Fig. 29 ), surstylus narrow and straight, covered with few short hairs. Epandrium parallel-sided in lateral view ( Fig. 38 ), surstyli broad, narrowing and round apically. Aedeagus with round pointed tip in lateral view ( Fig. 11 ). Gonite stout at base with rounded distal part in lateral view, appendage of gonite is located at significant distance from the tip ( Fig. 20 ).

NOTE. The species differs from E. afghanica in dark coloration of fore femora. The absence of long hairs on surtylus and unique shape of gonite with protruding apical lobe and narrow appendage placed at significant distance from it separate E. macellaria from E. attica and make it possible to determine this species with confidence. Mathis & Zatwarnicki [1995] mentioned “Caucasus” as the area of distribution of this species. However, all specimens from Caucasus, which we found in the collection, belong to E. attica .

The species is divided into 2 subspecies. E. macellaria alandica differs in entirely whitish-grey dusted coloration and is distributed in Finland, Norway and Sweden on the shore of Baltic Sea [ Wirth, 1975] and in Russia on the shore of White Sea. The second subspecies E. macellaria macellaria differs in metallic greenish subshining frons, scutum and abdomen and is widely distributed in the Palaearctic and Afrotropical Regions. Male genitalia of these subspecies are identical.

DISTRIBUTION. Russia: Altai, Karelia. — Afrotro-pical: Cape Verde Islands; Palearctic: Afghanistan, Algeria, Azores, Bulgaria, Canary Islands, China (NE Tibet), Cyprus, Czech Republic, Egypt, Finland, France, Germany, Great Britain, Greece, Iran, Italy, Libya, Madeira Islands, Malta, Morocco, Netherlands, Norway, Romania, Sweden, Tunisia, Turkmenistan, Ukraine [ Mathis, Zatwarnicki, 1995]; Kyrgyzstan (first record), Mongolia (first record), Tadjikistan (first record).
