Short description. General coloration grey and brown ( Fig. 10A View FIGURE 10 ). Head. Grey to ocherous grey, often slightly bluish tinged; anterior part of vertex with dark marking. Antenna about three times as long as head. Scape and pedicel dusky yellow to dark brownish grey. Flagellum dusky yellow to brown; basal flagellomeres often paler.

Thorax. Grey to greyish ocherous. Notum and pleuron mottled with dark brown spots and stripes. Wing ( Fig. 10B View FIGURE 10 ) tinged with dark brown, spotted with dark brown: seven markings at anterior margin; tips of most veins at wing margin and all crossveins each with dark spot or seam; large spot at subapical part of A 1. Legs mainly yellow; each femur sometimes with weakly dark apical or subapical band, at most three times as long as wide. Halter dusky yellow; knob dark brown.

Abdomen. Pregenital segments brown to dark brown, caudal margin of each segment darker. Male terminalia ( Figs 10C–G View FIGURE 10 ) with outer gonostylus dorsoventrally flattened, bearing small tooth at tip; outer margin of outer gonostylus with subapical lobe; apical inner edge angled at about 100 degrees with rounded corner ( Fig. 10D View FIGURE 10 ). Paramere with mesal-apical lobe flat finger-shaped, about three times as long as wide and lateral lobe ( Fig. 10G View FIGURE 10 ). Aedeagus relatively stout, about four times as long as wide, directed posterodorsally on basal part, curved posteriorly at middle ( Fig. 10F View FIGURE 10 ). Apodeme of vesica directed ventrally ( Fig. 10F View FIGURE 10 ).

Measurements. Male (n = 42): body length: 3.3–6.6 mm; wing length: 4.4–7.5 mm. Female (n = 22): body length: 5.0– 8.6 mm; wing length: 5.1–8.8 mm.

Distribution. Japan (Honshu, Shikoku, and Kyushu), Kuril Islands (Kunashir Is) ( Fig. 13E View FIGURE 13 ), Russia, North Korea, and South Korea.

Remarks. The subspecies of this species was distinguished from the nominotypical subspecies by colorations of antenna and femoral tip. Each of these characters varies even in specimens from the same locality. Based on no distinct morphological difference in the group, E. s. yezoensis is synonymized with the nominotypical subspecies. See remarks in E. persalsa for comparison to similar species.
