( Figs 76–85 )

Type material. Holotype 3, Korea: Mureung valley, Samhwa-dong, Donghae-si, GW, MT, 31.VIII–10.IX.2006, J. Lee leg. Paratype: 1 3, same collection data as holotype.

Diagnosis. This species similar to E. idaten Terayama 2006 by having body entirely polish; mandible with apical tooth; each scutellar pit separated from each other by more than 1.0 × as its maximum diameter; metacarpus as long as pterostigma. However, this new species has legs black except tibia and tarsi light castaneous; interspace between punctures on frons coriaceous; antenna short, not exceeding posterior margin of propodeal disc; propodeal disc 0.6 × as long as wide; whereas E. idaten has leg black except femora and basal half of tibia dark castaneous; apical half of tibia and tarsi light castaneous; interspace between punctures on frons smooth; antenna long, exceeding posterior margin of propodeal disc; propodeal disc as long as wide.

Description. MALE (holotype). Body length 6.1 mm ( Fig. 76 ); LFW 3.8 mm ( Fig. 81 ).

Color. Body black; mandible castaneous except frontal surface black, palpi light castaneous; clypeus black; antenna dark castaneous except posterior portion of scape and pedicel castaneous, fore wing subhyaline, veins castaneous, darkening distad; legs black except tibia and tarsi light castaneous.

Head ( Figs 77–79 ). 1.0 × as long as wide. Vertex badly convex with corners rounded ( Fig. 77 ). Temple profile almost parallel. Mandible with single apical tooth. Clypeus with angulate median lobe, median carina high ( Fig. 78 ). First five antennal segments in ratio of 2.6: 1.0: 1.4: 1.6: 1.7 in length; from scape to flagellomere 3 and flagellomere 11 2.6, 1.2, 1.5, 1.7, 1.9 and 3.0 × as long as wide respectively ( Fig. 79 ). Frons almost polished, punctures on anterior half dense than posterior half, separated from each other by 1.0–3.0 × as its maximum diameter. Eye 0.5 mm long with short and sparse hairs; HE 1.2 × OOL; WF 2.7 × WOT. Frontal angle of ocellar triangle obtuse, POL 1.6 × AOL, OOL 1.5 × WOT.

Mesosoma ( Figs 80–82 ). Pronotal disc 0.6 × as long as wide, coriaceous with dense punctures, punctures concentrated on anterior half, dorso-lateral corner forming obtuse angle. Mesoscutum coriaceous with dense punctures as pronotal disc. Notauli slightly narrowing and divergent anterad. Parapsidal furrows narrow and parallel. Scutellum coriaceous with sparse punctures, scutellar pit oval, each pit separated from each other by 1.1 × as its maximum diameter. Mesopleuron coriaceous with complete oval fovea in central area, margin with groove. Propodeal disc 0.6 × as long as wide, lateral margin getting wide posteriorly, median carina present, distinct submedian carinae absent, median carina completely reaching posterior carina, median area slightly depressed with irregular rugae, sublateral area smooth with many fine transverse rugae, transverse carina concave in middle, posterior margin of disc with eight short, longitudinal carinae excluding lateral and posterior carina; median longitudinal carina of declivity present, lateral of propodeum coriaceous ( Fig. 82 ). Fore wing with short metacarpus, 0.8 × as long as pterostigma; transverse-median vein strongly convex posteriorly ( Fig. 81 ).

Metasoma ( Fig. 83 ). Petiolate. Terga 1–2 smooth with a few fine punctures, terga 3–7 coriaceous with dense long hairs. Hypopygium wider than long with concave basal margin and median stalk; apical margin rounded with median long hairs.

Genitalia ( Figs 84, 85 ). Paramere broad base and round apex, sclerotized. Basiparamere longer than paramere. Cuspis with sclerotized apex and not divided into two lobes. Digitus apex not surpassing cuspis apex and directed outward. Aedeagus bottle-shaped, apex not surpassing cuspis apex; apodeme with base mesad; basal margin straight.

FEMALE. Unknown.

Distribution. Korea (GW).

Etymology. The specific name refers to the type locality.
