( Figs 96–105 )

Type material. Holotype 3, Korea: Mt. Gwanggyosan, Suji-gu, Yongin-si, GG, MT, 37°19'51.5"N, 127°02'36.9"E, 256 m, 8.VIII–5.IX.2008, J. Lim leg. Paratypes: 2 3, Mt. Homyeongsan, Goseong-ri, Cheongpyeong-myeon, Gapyeong-gun, GG, MT, 37°43'16.3"N, 127°29'23.4"E, 220 m, 5–18.IX.2009, J. Lim leg.

Diagnosis. This species similar to E. idaten Terayama 2006 by having similar body habitus; head as long as wide with straight posterior margin; mandible with one apical tooth; anterior margin of clypeus sharpened; median area of propodeal disc triangular and reticulate. However, this new species has antenna short, not exceeding the propodeal disc; distal two thirds of femora dark castaneous; metacarpus longer than pterostigma; propodeal disc distinctly shorter than wide; posterior carina on propodeal disc concave in middle with obtuse angle; whereas E. idaten has antenna long, exceeding tergum 1; distal two thirds of femora light castaneous; metacarpus shorter than pterostigma; propodeal disc as long as wide; posterior carina on propodeal disc slightly concave medially.

Description. MALE (holotype). Body length 5.4 mm ( Fig. 96 ); LFW 3.1 mm ( Fig. 101 ).

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

Head ( Figs 97–99 ). 1.0 × as long as wide. Vertex broadly straight with rounded corner ( Fig. 97 ). Temple profile parallel. Mandible with single tooth. Clypeus with angulate median lobe, median carina high ( Fig. 98 ). First five antennal segments in ratio of 2.2: 1.0: 1.4: 1.6: 1.6 in length; from scape to flagellomere 3 and flagellomere 11 2.1, 1.3, 1.6, 1.7, 1.6 and 3.8 × as long as wide, respectively ( Fig. 99 ). Frons coriaceous with dense punctures, puncures concentrated in anterior four fifths of LH, distal one fifth with sparse punctures. Eye 0.4 mm long with short and sparse hairs; HE 1.0 × OOL; WF 2.5 × WOT. Frontal angle of ocellar triangle obtuse, POL 1.4 × AOL, OOL 1.6 × WOT ( Fig. 97 ).

Mesosoma ( Figs 100–102 ). Pronotal disc 0.6 × as long as wide ( Fig. 100 ), coriaceous with dense punctures, separated from each other by 1.0–2.0 × as its maximum diameter, 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 0.5 × as long as wide, lateral margin slightly getting wide distally, median carina present, submedian carinae absent, median carina completely reaching posterior carina, basal reverse triangle median area smooth, depressed with some oblique rugae, narrow transverse rugae present along with basal triangle area, sublateral area coriaceous with very narrow transverse rugae, posterior carina concave in middle with obtuse angle; median longitudinal carina of declivity present, lateral of propodeum coriaceous ( Fig. 102 ). Fore wing with long metacarpus, 1.2 × as long as pterostigma; transverse-median vein arched ( Fig. 101 ).

Metasoma ( Fig. 103 ). Petiolate. Terga 1–2 smooth with few small, sparse punctures, terga 3–7 coriaceous with posterior half of each tergum with dense long hairs. Hypopygium wider than long with concave basal margin and median short stalk; apical margin round with median long hairs.

Genitalia ( Figs 104, 105 ). Paramere with narrow base and round apex, sclerotized. Basiparamere longer than paramere. Cuspis with sclerotized apex and not divided into two lobes. Digitus apex surpassing cuspis apex and mesad. Aedeagus bottle shaped, apex not surpassing cuspis apex; apodeme with base mesad; basal margin straight.

FEMALE. Unknown.

Distribution. Korea (GG).

Etymology. The specific name refers to the fine rugae on sublateral area of propodeal disc.
