Frontovertex 1.25 × as wide as eye height. Vertex almost smooth, sparsely punctate between median ocellus and eyes, with AOL as long as OOL; OOL 1.5 × OD; POL 2.4 × OOL; orbital surface superficially transversely alutaceous, laterally with fine sparse setae directed upwards; malar area superficially wrinkled; malar space 0.57 × as long as eye height in lateral view; malar carina faint and polished; gena coarsely foveolate, nearly bare; post-orbital carina well developed, joined genal carina at a level distinctly above the ventral edge of the eye, distinctly converging to the higher edge of the eye; preorbital and suborbital carinae developed. Occipital area densely reticulate; interantennal distance distinctly short, 0.4 × as long as torulus diameter, interantennal projection well developed (lamellate); frontal lobe relatively long (subantennal distance 3.3 × as long as interantennal distance), free margin with three lobes.

Antenna (Fig. 11D). 13-segmented, clava bi-segmented, with few scattered short setae; scape moderately long, longer than eye height (1.33 ×), ending a distance before median ocellus, densely punctured throughout; pedicel relatively short, conical shape, approximately as long as its width; anellus transverse, ca. 0.6 × as long as wide; F1 relatively long, 1.75 × as long as wide, following funiculars distinctly shorter, subequal; clava ca. 2.7 × as long as wide, tapered apically.

Mesosoma (Figs 11E, 12A, B). 1.8 × as long as mesoscutum width, with relatively short setae, that are somewhat thickened on pronotum and mesoscutellum. Pronotal collar 3.0 × as wide as long, sparsely setiferous foveolate, that are denser laterally, with sides slightly convex; humeral angle sharp, nearly 90°; lateral carina not extended dorsally on collar. Mesoscutum 2.9 × as long as pronotal collar median length, sparsely finely punctulate on anterior half of middle lobe, its anterior margin finely alutaceous; posterior half of middle lobe with large irregular foveolae, lateral lobes with dense setiferous punctures. Notauli very distinct and deep, linear (not crenulate). Tegula broadly rounded posteriorly, smooth. Mesoscutellum slightly longer than wide (1.1 ×), setiferous foveolate, foveolae smooth on bottom, with posterior margin broadly rounded. Propodeum strongly areolate, median areola slightly widened posteriorly, 2.6 × as long as wide, weakly transversely striated on bottom, its lateral carinae slightly diverging posteriorly and reaching transverse carina of adpetiolar areola; submedian and basolateral areolae fused. Mesopleuron with adscrobal area coarsely foveolate, foveolae finely punctate inside; femoral scrobe coarsely transversely ridged, ventral shelf of mesepisternum finely punctate, with adpressed setae. Metepimeron densely, closely foveolate throughout, with fine, adpressed setae; metepisternum largely areolate throughout (bottom of areolae densely reticulate), with two median carinae slightly diverging posteriorly followed by two large and sharp submedian teeth; adpetiolar area concave, nearly smooth, with a median longitudinal carina ends posteriorly with a strong subpentagonal areola.

Wings (Fig. 12C). Fore wing ca. 3.0 × as long as wide, rather densely setose on the underside of apical two-thirds, setae distinctly long; MV 0.6 × as long as costal cell; STV somewhat reduced (0.1 × as long as MV), 2.0 × as long as wide, forming with anterior margin an angle of ca. 45°. Hind wing sparsely setose apically, with three hamuli.

Hind leg (Figs 10C, 13A, B). Metacoxa 2.2 × as long as wide, widened basally, slightly shorter than metafemur (0.9 ×), finely transversely alutaceous on outer dorsal face, rest densely setiferous punctulate, interspaces between punctures smooth. Metafemur 1.75 × as long as wide, with dense setiferous punctures throughout, outer ventral margin with broad triangular tooth basally, followed by a serrulation of minute teeth. Metatibia with an oblique carina inside metatibial process; tarsal scrobe almost reaching sub-basal prominence; sub-basal prominence is formed from three small blunt teeth partly hidden by dense pubescence.

Metasoma (Figs 10A, B, 12A, 13C). Petiole relatively short, 3.5 × as long as wide, 0.92 × as long as dorsal length of Gt1, and ca. 0.6 × as long as gaster, with an incomplete median carina (0.45 × as long as petiole length), two incomplete submedian carinae (0.73 × as long as petiole length), and two complete lateral ridge, area between sublateral ridges nearly smooth and shiny. Gaster fusiform in dorsal view, 1.55 × as long as its height in profile. Gt1 0.6 × as long as the whole length of gaster in dorsal view, deeply concave posteriorly, almost entirely smooth; remaining tergites short, densely finely punctate at base, finely setose. Gt2 slightly concave posteriorly. Ovipositor slightly extended behind gaster.

Color (Figs 10A-C, 12C). Body generally reddish to reddish brown, with the following parts black: head (except lateral sides just below lower edge of eyes, and frontal lobe), anterior margin of mesoscutum middle lobe, propodeum (except postero-lateral margins). Metasoma dark reddish brown; antenna with scape and pedicel bright red, rest reddish brown; tegula testaceous. Wings hyaline with yellowish brown veins that are paler on hind wing.

Remarks.

The new species closely similar to E. inops, but differs in the following: metatibia with oblique carina inside metatibial process (Fig. 13B) (metatibia without such carina in E. inops (Fig. 27C)); tarsal scrobe almost reaching sub-basal prominence (Fig. 13B) (tarsal scrobe short, far from reaching sub-basal prominence in E. inops (Fig. 27C)); frons with supra antennal surface completely delimited by a step-like margin (Fig. 11A) (supra antennal surface delimited only laterally by faint step-like ridge in E. inops (Fig. 26A)); mesoscutum with short, very small and sparse punctures on anterior part of middle lobe, while posterior area with coarse irregular foveolation (Fig. 11E) (setae on mesoscutum longer, denser and coarser on the whole middle lobe in E. inops (Fig. 25B)); mesoscutellum convex when seen in profile (Fig. 10A) (flat in E. inops (Fig. 25A)).
