( Figs 179–186 )

Type material. Holotype Ƥ, Korea: Donam-ri, Banpo-myeon, Gongju-si, CN, 2–8.VIII.2007, MT, Y. Kim leg. Paratypes: 2 Ƥ, same locality as the holotype, 19–26.VII.2005, MT, Y. Kim leg.; 1 Ƥ, ditto, 5–13.VI.2005, MT, Y. Kim leg.; 1 Ƥ, ditto, 23–29.VII.2007, MT, Y. Kim leg.; 1 Ƥ, ditto, 8–14.IX.2007, MT, Y. Kim leg.

Diagnosis. This species is similar to E. hagoromonis Terayama 1999 by having head slightly longer than wide with convex posterior margin; anterior margin of clypeus round; each scutellar pit rectangular and separated from each other by thin septum; propodeal disc with strong three discal carinae. However, this species has antenna castaneous except basal four fifths of scape dark castaneous; head with straight posterior margin in dorsal view; mandibles with five teeth; and each scutellar pit separated from each other by 1.5 × as its maximum diameter; whereas E. hagoromonis has antenna castaneous except basal two thirds of scape dark castaneous; head with convex posterior margin in dorsal view; mandible with two teeth; each scutellar pit separated from each other by 4.0 × as its maximum diameter.

Description. FEMALE (holotype). Body length 3.2 mm ( Fig. 179 ); LFW 2.0 mm ( Fig. 181 ).

Color. Body black except posterior margin of metasomal terga castaneous; mandible castaneous except apical half light castaneous; antenna castaneous except basal four fifths of scape dark castaneous; fore wing subhyaline, veins castaneous; coxa and femora dark castaneous, trochanter, tibia and tarsi light castaneous except middle part of tibia with castaneous band.

Head ( Figs 180, 182, 183 ). 1.1 × as long as wide. Vertex convex with corners broadly rounded. Temple profile divergent anterad. Frons strongly coriaceous, small puncture separated from each other by 2.0–3.0 × as its maximum diameter ( Fig. 182 ). Mandible with five apical teeth; upper four teeth intermediate size, lower tooth most large and sharpened. Clypeus with subrounded median lobe ( Fig. 183 ). First five antennal segments in ratio of 5.4: 1.6: 1.3: 1.2: 1.0 in length, from scape to flagellomere 3 and 11 3.3, 1.3, 0.9, 0.8, 0.6 and 1.8 × as long as wide respectively ( Fig. 180 ). Eye 0.24 mm long with erect hairs, HE 0.9 × OOL; WF 2.8 × WOT. Frontal angle of ocellar triangle obtuse, POL 1.3 × AOL, OOL 2.0 × WOT ( Fig. 182 ).

Mesosoma ( Figs 181, 184, 186 ). Pronotum coriaceous, punctures very shallow, 0.6 × as long as wide, anterior corners forming round angle. Mesoscutum coriaceous. Notauli narrow, divergent anterad. Parapsidal furrows divergent anterad. Scutellar disc coriaceous, punctate as head, each scutellar pit subrectangular, 1.5 × as long as wide, each pit separated from each other by narrow septum ( Fig. 184 ). Propodeal disc 0.8 × as long as wide with lateral margin parallel, five discal carinae present, median and lateral discal carinae reaching posterior carina and submedian carinae not reaching posterior carina, median area with coarse transverse rugae, sublateral area strigate coarsely, propodeal declivity coriaceous with median longitudinal carina ( Fig. 186 ), lateral of propodeum coriaceous. Fore wing without metacarpus; transverse-median vein slightly arched ( Fig. 181 ).

Metasoma ( Fig. 185 ). Petiolate and smooth. Terga 1–3 without punctures, remained terga with very small punctures.

MALE. Unknown.

Distribution. Korea (CN).

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