Material examined. HOLOTYPE female, JAPAN, Honshu, Hida (Gifu), Ontake , 27.VII.1959, Mishima ( E. hidana / USNM) . PARATYPES: NORTH KOREA: 1 male, Seren Mts. , 3000 feet, 5.VII.1938, Yankovsky ( E. persalsa / USNM) ; 1 male, same data as previous except 3700 feet, 30.VI.1938 . Non-type material: JAPAN: [Honshu] 2 males, Nagano, Sakae-mura, Sakai, Koakazawa-gawa River , Alt. 1320–1500 m, 9.VII.2019 , D. Kato ( BLKU); 2 females, same data as previous except 23.VII.2019 .

Short description. General coloration ocherous to brown ( Fig. 9A View FIGURE 9 ). Head. Grey to dark grey. Antenna about 2.5 times as long as head. Scape dark grey. Succeeding segments pale brown.

Thorax. Unmarked, sometimes weakly greyish. Wing ( Fig. 9B View FIGURE 9 ) tinged with pale brown, sparsely patterned with dark brown: costal region with seven dark spots; tips of most veins at wing margin and all crossveins each with dark spot or seam. Legs mainly yellow; each femur with dark tip, about three times as long as wide. Halter pale yellow.

Abdomen. Pregenital segments weakly dark on posterior part of each segment. Male terminalia ( Figs 9C–G View FIGURE 9 ) with outer gonostylus bearing small apical claw-shaped lobe directed medially; outer margin serrate on distal 1/3; inner margin on apical part rounded and serrate ( Fig. 9D View FIGURE 9 ). Paramere with mesal-apical lobe flat and wide, about 1.5 times as long as wide and slightly longer than lateral lobe, rounded and broad on distal part ( Fig. 9G View FIGURE 9 ). Aedeagus almost straight, about six times as long as wide in lateral view ( Fig. 9E View FIGURE 9 ). Apodeme of vesica indistinct ( Fig. 9E View FIGURE 9 ).

Measurements. Male (n = 4): body length: 5.5–7.5 mm; wing length: 6.5–8.0 mm. Female (n = 3): body length: 7.0– 7.7 mm; wing length: 7.5–8.8 mm.

Distribution. Japan (Honshu), Kuril Islands (Kunashir and Shikotan Is) ( Fig. 13D View FIGURE 13 ), Russia, North Korea, Mongolia, and Kazakhstan.

Remarks. This species is very similar to a Japanese species, E. hidana , whose male was unknown. As a result of examining the males, E. hidana is considered to be a synonym of E. persalsa , based on the structure of male terminalia. In terms of general appearance, E. persalsa is somewhat similar to E. subaprilina , but is differentiated from it by the following characters: notum and pleuron unmarked or almost so (distinctly patterned with dark markings in E. subaprilina ); wing with one dark spot on distal part of A 1 ( Fig. 9B View FIGURE 9 ) (two dark spots in E. subaprilina ( Fig. 10B View FIGURE 10 )); knob of halter pale yellow (dark brown in E. subaprilina ); outer gonostylus without lobe besides apical lobe ( Fig. 9D View FIGURE 9 ) (with small lobe at outer margin near tip besides apical lobe in E. subaprilina ( Fig. 10D View FIGURE 10 )).
