( Figs 133–139 )

Type material. Holotype Ƥ, Korea: Mt. Gwanggyosan, Suji-gu, Yongin-si, GG, 37°19'56.8"N 127°02'37.8"E, 214 m, MT, 21–30.V.2008, J. Lim leg. Paratypes: 2Ƥ, Donam-ri, Banpo-myeon, Gongju-si, CN, MT, 16.V–6.VI.2007, MT, Y. Kim leg.

Diagnosis. This species is similar to E. tennyo Terayama 2006 by having antenna testaceous except basal three fourths of scape black; head and pronotal disc microreticulate with moderately punctuate; fore wing with small metacarpus; propodeal disc with median and pair of submedian carinae. However, this new species has mandible with two teeth; clypeus long and anteriorly truncate; punctures of head and mesosoma separated from each other by 2.0–2.5 × as its maximum diameter; whereas E. tennyo has mandible with one tooth; clypeus short and obtuse anteriorly; punctures of head and mesosoma separated from each other by 3.0–5.0 × as its maximum diameter.

Description. FEMALE (holotype). Body length 4.9 mm ( Fig. 133 ); LFW 2.6 mm.

Color. Body black; mandible dark castaneous; antenna dark castaneous except basal two thirds of scape black; fore wing subhyaline, veins castaneous; legs light castaneous except coxa and femora black.

Head ( Figs 134, 135, 137 ). Polished, 1.1 × as long as wide. Vertex slightly convex with rounded corners. Temple profile divergent anterad. Frons almost polished, punctures somewhat strong, each puncture separated from each other by 2.0–2.5 × as its maximum diameter ( Fig. 135 ). Mandible with truncate two teeth, upper tooth large, about 2.0 × as lower tooth ( Fig. 137 ). Clypeus with well projected trapezoidal median lobe. First five antennal segments in ratio of 3.2: 1.4: 1.0: 1.4: 1.3 in length; from scape to flagellomere 3 and 11 2.2, 1.6, 1.0, 1.5, 1.4 and 1.8 × as long as wide, respectively ( Fig. 134 ). Eye 0.39 mm long with short erect hairs. HE 1.0 × OOL; WF 3.0 × WOT. Frontal angle of ocellar triangle right, POL 1.1 × AOL; OOL 2.0 × WOT ( Fig. 135 ).

Mesosoma ( Figs 136, 139 ). Pronotum coriaceous, punctate as head, 0.7 × as long as wide, posterior margin concave. Mesoscutum coriaceous, punctate as head and pronotum. Notauli divergent anterad. Scutellar disc coriaceous and coriaceous and punctate as head and pronotum, connected with anterior margin of propodeum, scutellar pit oval, each pit separated from each other by 2.5 × as its maximum diameter ( Fig. 136 ). Propodeal disc polished, 0.9 × as long as wide with posterior margin straight and lateral margin parallel in dorsal view, three discal carinae present, median discal carina reaching posterior carina, submedian discal carinae reaching 0.8 × of disc length, median area regulose, sublateral area strigate and rugulose; propodeal declivity coriaceous with median longitudinal carina ( Fig. 139 ), lateral surface of propodeum coriaceous. Fore wing with short metacarpus, 0.2 × as long as pterostigma.

Metasoma ( Fig. 138 ). Petiolate and polished with very fine punctures and few hairs.

MALE. Unknown.

Distribution. Korea (CN, GG).

Etymology. The specific name is an aleatory combimation of letters with ending - us.
