( Figs 172–178 )

Type material. Holotype 3, Korea: Mt. Sudosan, Jeungsan-myeon, Gimcheon-si, GB, 400 m, 23.VIII.1990, K. Yamagishi leg. Paratypes: 1 Ƥ, same data as holotype, 23.VIII.1990, K. Yamagishi leg.; 1 Ƥ, Muwisa, Mt. Wolchulsan, Galryong-ri, Jeongcheon-myeon, Jinan-gun, JB, VII–X.2009, J. Jung leg.

Diagnosis. This species is similar to E. fujianensis Xu, He et Ma 2003 by having head polish with parallel lateral margin; anterior margin of clypeus with right angle; pronotal disc polish; each scutellar pit separated from each other by more than 1.0 × as its maximum diameter; propodeal disc with three discal carina. However, this species has fore coxa dark castaneous; scape about 4.0 × as long as pedicel; head with sparse punctures; submedian carinae on propodeal disc convergent suddenly in middle part; whereas E. fujianensis has fore coxa black; scape about 3.0 × as long as pedicel; head with dense punctures; submedian carinae on propodeal disc parallel in middle part.

Description. Holotype (female). Body length 4.4 mm ( Fig. 172 ); LFW 2.6 mm ( Fig. 178 ).

Color. Head and mesosoma black, except anterior margin of pronotal collar dark castaneous; metasoma dark castaneous with half of distal part light castaneous; mandible dark castaneous; antenna castaneous except basal three fourths of scape, flagellomere 5–11 dark castaneous; wing veins castaneous; legs dark castaneous.

Head ( Figs 173, 174, 177 ). Polished, 1.2 × as long as wide. Vertex slightly convex with rounded corners. Temple profile divergent anterad. Frons weakly coriaceous, each puncture separated from each other by 2.0–4.0 × as its maximum diameter ( Fig. 173 ). Mandible with single sharpened apical tooth. Clypeus with subangulate median lobe ( Fig. 174 ). First five antennal segments in ratio of 4.3: 1.0: 1.1: 1.3: 1.2 in length; from scape to flagellomere 3 and 11 2.3, 0.9, 0.9, 1.0, 0.9 and 2.2 × as long as wide respectively ( Fig. 177 ). Eye 0.27 mm long with erect hairs, HE 0.7 × OOL; WF 3.3 × WOT. Frontal angle of ocellar triangle right, POL 1.1 × AOL, OOL 2.4 × WOT ( Fig. 173 ).

Mesosoma ( Figs 175, 176, 178 ). Pronotum coriaceous, punctate as head, 0.7 × as long as wide, anterior corners forming round angle. Mesoscutum polished, anterior half coriaceous, unpunctate, posterior half coriaceous, punctate as head and pronotum. Notauli divergent anterad. Parapsidal furrows divergent anterad. Scutellar disc coriaceous, punctate as head and pronotum, scutellar pit oval, each pit separated from each other by 2.0 × as its maximum diameter ( Fig. 175 ). Propodeal disc polished, 0.9 × as long as wide with lateral margin parallel in dorsal view, three discal carinae present, sublateral carina absent, median discal carina reaching posterior carina, submedian carinae reaching 0.8 × of disc length and convergent at middle part, median area with coarse oblique rugae, sublateral area strigate, propodeal declivity coriaceous with median longitudinal carina ( Fig. 176 ), lateral surface of propodeum coriaceous. Fore wing with short metacarpus, 0.4 × as long as pterostigma; transverse-median vein strongly convex posteriorly ( Fig. 178 ).

Metasoma: Petiolate and smooth. Terga 1–2 without distinct punctures, remained terga with dense fine punctures distally.

MALE. Unknown.

Distribution. Korea (GB, JB).

Etymology. The specific name refers to the type locality.
