Thorax black, gray pollinose, dorsum with 4 longitudinal black vittae extending back to anterior half of postsutural scutum, narrower inner vitta 1/3–1/4 width of pruinose portion between inner and outer vittae; scutellum reddish-brown at apex, with gray pruinosity; anterior and posterior spiracles brown-yellow, posterior lappet of posterior spiracles subcircular. Prosternum bare, about 2.5 times as long as wide, proepisternum bare, 4–5 postpronotal setae, 3 strongest arranged in a triangle; 2 presutural and 2 to 3 postsutural acrostichal setae, 3 presutural and 4 postsutural dorsocentral setae; 3 (rarely 2) postsutural intra-alar setae; 3 supra-alar setae; 3 katepisternal setae; katepimeron hairy; scutellum with 3 pairs of strong marginal setae and a pair of discal setae, apical setae crossed. Wing yellowish except base and anterior portion yellow, hyaline; tegula and basicosta reddishyellow to brown; costal spine shorter than crossvein r-m; 2nd costal sector bare ventrally, relative length of 2nd, 3rd and 4th costal sections approximately 1:2.5:1; base of vein R 4+5 with setulae dorsally and ventrally; vein M nearly right-angled at bend, with a short appendage; section of vein M between crossveins r-m and dM-Cu 2.0–2.3 times as long as section between dM-Cu and bend; cell r 4+5 open. Halter yellow; calypter yellowish white, lower calypter with long fringe on outer margin. Legs dark brown except for reddish yellow tibiae and apices of femora; pulvilli yellowish, claws dark. Fore tibia with a row of 5–6 short anterodorsal setae and 2 posterior setae; fore claws and pulvilli slightly longer than 5th tarsomere; mid tibia with 2–3 (1 lower strong and 1–2 upper small) anterodorsal setae, 2 posterodorsal and 1 ventral setae; hind tibia with 3–4 anterodorsal, 3 posterodorsal and 2 ventral setae, 2 preapical dorsal setae.

We did not examine the holotype of this species and recognized it from the description of Herting (1968) . It is similar to E. magna (Baranov) , but differs in having reddish-yellow palpi, wing yellow at base and in anterior portion, abdominal tergites covered with densely yellowish-gray or grayish-white pruinosity, without dark brown markings on tergite 3.
