DESCRIPTION. Head golden or silvery-grey-bluish pollinose except metallic shining frontal vitta and upper face; fronto-orbital plate grey pollinose. 3–4 long fronto-orbital setae, 3 interfrontal setae thin and short, anterior seta strongest, 1/3 as long as ocellar. Postocular setae short and thin. Palpus yellow. Antenna blackish, greyish dusted; arista pectinate on dorsal surface on 2/3. Gena and parafacial grey dusted.

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

Legs. Femora from yellow to black, grey dusted; tibiae and tarsi yellow, darkened dorsally.

Abdomen black, grey pollinose, subshining with bluish tinge. Tergite 5 about to 1.5–2 times as long as tergite 4. Male genitalia large, as long as tergites 4+5. Epandrium round-oval in dorsal (posterior) view ( Fig. 26 ), a little wider near base of surstyli; surstyli straight and widened at apex, parallel-sided apically, with many relatively long perpendicular hairs. Epandrium parallel-sided in lateral view ( Fig. 35 ); surstylus straight, broad, pointed apically. Aedeagus with round tip in lateral view ( Fig. 8 ). Gonite stout at base with round tip in lateral view, subapical process of moderate length ( Fig. 17 ).

NOTE. The species resembles E. afghanica in yellow coloration of legs in some specimens, but differs in the shape of surstyli which are widened apically in dorsal view and covered with setae. The specimens with dark tibiae may be separated from E. macellaria by the presence of long setae on surstyli; this character is clearly visible even in dry specimens.
