Short description. General coloration grey and dark brown ( Fig. 4A View FIGURE 4 ). Head. Grey to greyish ocherous with dark central stripe on vertex and dark lateral area on posterior part of vertex. Antenna about twice as long as head. Scape and pedicel dark brownish grey. Flagellum dusky yellow.

Thorax. Grey to greyish ocherous. Notum and pleuron mottled with dark brown spots and stripes. Wing ( Fig. 4B View FIGURE 4 ) subhyaline, heavily patterned with numerous small spots in cells and large markings. Legs mainly yellow; each femur with dark band at tip, 4–5 times as long as wide. Halter pale yellow; knob dark brown.

Abdomen. Brown; pregenital segments weakly dark on posterior part of each segment. Male terminalia ( Figs 4C–G View FIGURE 4 ) with outer gonostylus strongly narrowed on distal 1/4 into strongly curved, claw-shaped lobe, with subapical lobe at outer margin; apical inner edge angulated at almost right angle with rounded corner ( Fig. 4D View FIGURE 4 ). Paramere with mesal-apical lobe blade-shaped, subacute at tip, about four times as long as wide and 1.5 times as long as lateral lobe ( Fig. 4G View FIGURE 4 ). Aedeagus about six times as long as wide in lateral view, curved near middle and directed posteriorly on distal part ( Fig. 4F View FIGURE 4 ). Apodeme of vesica directed ventrally ( Fig. 4F View FIGURE 4 ).

Measurements. Male (n = 6): body length: 4.0– 4.8 mm; wing length: 5.0– 5.8 mm.

Distribution. Japan (Honshu, Shikoku, Kyushu, and Nansei Islands) and Kuril Islands (Kunashir Is) ( Fig. 13B View FIGURE 13 ).

Remarks. This species resembles two Chinese species, E. similissima ( Alexander, 1941) and E. suensoni ( Alexander, 1926) , but is differentiated from them by the following characters: flagellomeres on intermediate segments yellowish, not bicolorous (bicolorous, base of each segment slightly darkened in E. suensoni ); each femur with dark band at tip (slightly pale at extreme tips of dark band in E. suensoni ; outer face of dark band close to tips more reddish in E. similissima ); outer gonostylus with distal claw-shaped part strongly curved, gradually narrow to tip ( Fig. 4D View FIGURE 4 ) (slightly curved, gradually narrow to tip in E. suensoni ; slender and strongly curved, middle part almost same in width in E. similissima ).
