Diagnosis
Female (Figs 2C, F, K, 6D). Body length 6.0–8.0 mm. Head and thorax black, except pronotum dorsally, tegula, cenchrus, apical half of fore femur, middle femur at apex, fore and middle tibiae anteriorly, basal 2/3 of hind tibia, basal half of hind tarsomere 1 white; labrum, labial and maxillary palps, fore and middle tibiae posteriorly (sometimes at apex), fore and middle tarsi brown; mandible at apex reddish brown; apical half of hind tarsomere 1 and tarsomeres 2–5 dark brown; abdomen black, segments with narrow posterior whitish (pale) margins, and abdominal terga with 3 pairs of whitish patches (the tergum 4 with small-sized or indistinct patch) (Fig. 2C, D, F, H, K, L). Malar space 1.2–1.7 times as long as diameter of median ocellus (Fig. 2K). Flagellum 1.7–2.0 times as long as head width. Claws simple or with small denticle. Ovipositor sheath extending beyond apex of abdomen; dorsal and ventral margins subparallel and apex truncated (Fig. 2F). Lancet with about 18 serrulae, membrane between serrulae weakly convex; each serrula circularly protruding basally (Fig. 6D), with a basal denticle and 3–6 distal denticles.
Male (Figs 2D, H, L, 7D). Body length 4.8–6.0 mm. Similar to female, but malar space 0.8–1.0 times as long as diameter of median ocellus (Fig. 2L). Flagellum 1.8–2.4 times as long as head width. Posterior margin of sternum 9 rounded. Penis valve as in Fig. 7D, valviceps almost equal in length to valvura.
Genetic data
Based on the COI barcode region of four specimens (China and Russia), the maximal distance between them is 3.8%. The nearest neighbour, diverging by a minimum of 5.0%, is E. nigroterga. Based on the nuclear data of three specimens (China and Russia), the maximal distance between them is 0.7%. The nearest neighbour, diverging by a minimum of 1.4%, is E. nigroterga.

Host plant
Unknown.
Distribution
South Korea (new record), Russia (new record), China (Yan et al. 2009[1]).
Remarks
Based on morphology, Prous (2012)[2] suggested that this species belongs to E. quadrimaculata group, which is here confirmed based on the genetic data. Compared to specimens from South Korea and Russia (Primorsky Krai), specimens studied from China (Hunan and Zhejiang) have longer antenna (flagellum about 2.0 times as long as head width in female, 2.3–2.4 times in male) and are larger (females 6.5–8.0 mm, males about 6.0 mm), but this could be due to geographic differences rather than indicating the presence of different species.
