( Figs 56–65 )

Type material. Holotype 3, Korea: Mureung Valley, Samhwa-dong, Donghae-si, GW, MT, 25–30.V.2005, J. Lee leg. Paratypes: 1 3, ditto, MT, 10–31.VIII.2005, J. Lee leg.; 1 3, ditto, MT, 31.V–15.VI.2005, J. Lee leg.; 1 3, ditto, 37°27'33.8"N, 129°23'56"E, MT, 20.IX–2.X.2006, J. Lee leg.

Diagnosis. This species is similar to E. kokuzoh Terayama 2006 by having metacarpus short, shorter than length of pterostigma; each scutellar pit separated from each other by more than 1.0 × as its maximum diameter; propodeum with pair of submedian carinae. However, this new species has legs black except tarsi castaneous; flagellomeres 2 and 3 approximately 2.0 × as long as wide; interspace between punctures on frons, vertex and pronotal disc completely smooth; OOL 1.5 × WOT; whereas E. kokuzoh has fore coxa and femora dark castaneous, and trochanter, tibia and tarsi castaneous; mid-, hind coxa, femora, and tibia dark castaneous; flagellomeres 2 and 3 approximately 1.4 × as long as wide; interspace between punctures on frons, vertex and pronotal disc completely coriaceous; OOL 1.0 × WOT.

Description. MALE (holotype). Body length 6.1 mm ( Fig. 56 ); LFW 4.2 mm ( Fig. 61 ).

Color. Body black, except posterior margin of metasomal terga dark castaneous; mandible castaneous and palpi castaneous; clypeus black; antenna dark castaneous except scape black; fore wing subhyaline, veins dark castaneous; legs black except tarsi castaneous.

Head ( Figs 57–59 ). 1.1 × as long as wide. Vertex slightly convex with rounded ( Fig. 57 ). Temple profile parallel. Mandible with single tooth. Clypeus with angulate median lobe ( Fig. 58 ). First five antennal segments in ratio of 2.0: 1.0: 1.2: 1.9: 2.0 in length; from scape to flagellomere 3 and 11 2.0, 1.2, 1.3, 1.8, 2.0 and 4.1 × as long as wide respectively ( Fig. 59 ). Frons completely smooth with sparse, large punctures. Eye 0.48 mm long with short and sparse hairs; HE 1.0 × OOL; WF 2.7 × WOT. Frontal angle of ocellar triangle obtuse, POL 1.5 × AOL, OOL 1.7 × WOT.

Mesosoma ( Figs 60–62 ). Pronotal disc 0.6 × as long as wide, punctures concentrated on anterior half and posterior half with sparse large punctures, interspace between punctures completely smooth. Mesoscutum smooth with dense punctures, denser than head and pronotal disc. Notauli narrowing and divergent anterad. Parapsidal furrows narrow and slightly divergent anterad. Scutellum smooth with sparse large punctures, scutellar pit oval, each pit separated from each other by 2.1 × as its maximum diameter. Mesopleuron smooth except anterior half weakly coriaceous with complete oval fovea in central area, margin with groove. Propodeal disc 0.7 × as long as wide, lateral margin parallel, three discal carinae present, median carina completely reaching posterior carina, submedian carinae almost reaching posterior carina and mostly parallel, posterior part of carina curved inward, median area slightly depressed with irregular rugae, sublateral area with many fine transverse rugae, sublateral carina absent, posterior margin of disc with ten longitudinal short carinae; median longitudinal carina of declivity present, lateral of propodeum coriaceous ( Fig. 62 ). Fore wing with short metacarpus, 0.4 × as long as pterostigma; transversemedian vein strongly convex posteriorly ( Fig. 61 ).

Metasoma. ( Fig. 63 ). Petiolate. Tergum 1 smooth with few fine punctures, tergum 2 smooth with punctures, denser than tergum 1, terga 2–7 smooth except anterior area coriaceous with transverse dense hairs. Hypopygium longer than wide with straight basal margin and median stalk; apical margin truncate with distal long hairs. Genitalia ( Figs 64, 65 ). Paramere broad with truncate apex and distal long hairs, dorsal margin membranous. Basiparamere as long as paramere. Cuspis with sclerotized apex and divided into apical two elongate lobes. Digitus apex not surpassing cuspis apex. Aedeagus cylindrical, with broad base and narrowing to apex, apex not surpassing cuspis apex; apodeme with base mesad; basal margin straight.

FEMALE. Unknown.

Distribution. Korea (GW).

Etymology. The specific name refers to the smooth, polished head and pronotal disc without microreticulation.
