Head behind eye (dorsal view) almost parallelsided in anterior half, distinctly and roundly narrowed in posterior half; transverse diameter of eye 1.2–1.4× as long as temple ( Figure 33 View Figures 32–43 ). Ocelli medium size, in triangle with base 1.4× its sides. POL 1.7–2.0× Od, 0.75× OOL. Eye glabrous, 1.2× as high as broad. Malar space height 0.4× height of eye, 0.8× basal width of mandible ( Figure 34 View Figures 32–43 ). Face width 0.9× height of eye and 1.2× height of face and clypeus combined. Clypeus with very narrow lower flange. Clypeal suture distinct and complete. Hypoclypeal depression round, its width 0.7–0.8× distance from edge of depression to eye, 0.45× width of face ( Figure 32 View Figures 32–43 ). Hypostomal flange very narrow. Antennae ( Figure 35 View Figures 32–43 ) weakly thickened, filiform, 37–39-segmented, 1.3× as long as body. Scapus 1.3× as long as its maximum width. First flagellar segment weakly curved outside, weakly flattened, 3.8–4.0× as long as its apical width, equal to or slightly shorter than second segment. First and second flagellar segments dorsally flat and almost glabrous. Penultimate segment 4.0–4.5× as long as its width, 0.6–0.65× as long as first segment, 0.8–1.0× as long as apical segment; the latter pointed apically.

Mesosoma . Length 2.4–2.5× its height ( Figure 36 View Figures 32–43 ). Mesoscutum weakly and roundly raised above pronotum. Pronotal keel fine. Notauli deep in anterior half, very shallow in posterior half, crenulate-granulate. Prescutellar depression shallow, wide, with median carina, densely rugulose, 0.2–0.4× as long as scutellum. Subalar depression shallow, wide, striaterugose with granulation. Sternauli rather shallow, but deep medially, narrow, straight, almost smooth, connected with prepectal carina anteriorly, running along almost entire length of lower part of mesopleura. Metapleural flange long, narrow, rounded apically.

Wings. Fore wing ( Figure 40 View Figures 32–43 ) 3.8–4.3× as long as its maximum width. Radial vein arising from middle of pterostigma. Metacarpus 1.1–1.15× as long as pterostigma. Second radial abscissa 3.5–4.0× first abscissa, 0.6× the straight third abscissa, 1.6–1.8× first radiomedial vein. Second radiomedial cell 3.4–3.6× as long as its maximum width, 1.5– 1.6× as long as brachial cell. First abscissa of medial vein weakly S-shaped. Recurrent vein 4.0–5.5× second abscissa of medial vein. Distance from nervulus to basal vein 1.7× nervulus length. Brachial cell closed apically weakly before level of recurrent vein. Hind wing ( Figure 41 View Figures 32–43 ) 5.5–5.7× as long as wide. First abscissa of costal vein 0.55× second abscissa. First abscissa of mediocubital vein 0.4–0.45× second abscissa. Recurrent vein short, weakly curved toward base of wing, unsclerotized for most part, distinctly antefurcal.

Legs. Hind coxa without basoventral tooth, its length almost twice maximum width ( Figure 37 View Figures 32–43 ). Hind femur 3.2–3.4× as long as wide ( Figure 38 View Figures 32–43 ). Hind tibia with six short and thick spines on apical outside margin ( Figure 39 View Figures 32–43 ). Hind tarsus almost as long as hind tibia. Basitarsus weakly thickened, 0.6× as long as second to fifth segments combined. Second tarsal segment 0.5–0.55× as long as basitarsus, almost as long as fifth segment (without pretarsus).

Metasoma. Metasoma ( Figure 43 View Figures 32–43 ) 1.1× as long as head and mesosoma combined. First tergite not high (lateral view) ( Figure 42 View Figures 32–43 ), distinctly and linearly widened from base to apex ( Figure 43 View Figures 32–43 ), with distinct and not long spiracular tubercles in basal 0.3 that are not directed downwards. Acrosternite of first tergite 0.25–0.3× as long as tergite. Maximum width of first tergite 1.7–1.85× its minimum width; length 2.1× its apical width. Second tergite with shallow, rather wide, weakly curved and weakly posteriorly convergent longitudinal lateral furrows; basal width of area 2.2–2.5× its apical width; length of tergite 1.3× its basal width, 1.4–1.6× length of third tergite. Second suture complete, rather deep (especially laterally), regularly curved or almost straight medially, without lateral bends.

Sculpture and pubescence. Vertex densely and finely transversely striate with dense fine granulation, striae semicircular laterally. Frons coarsely transversely striate with fine granulation between striae. Face distinctly transversely striate for most part, with fine granulation or coriaceous. Temple finely and densely transversely striate, coriaceous or almost smooth on lower 0.3. Mesoscutum densely rugulose-granulate, undulately striaterugose on rather narrow area in medioposterior half. Scutellum distinctly densely granulate. Mesopleura rugose-punctulate medially, finely punctulate-coriaceous above sternauli, smooth below sternauli. Metapleura entirely rugose-areolate with dense fine granulation. Propodeum entirely densely rugose-areolate, with fine median carina in basal half, without areas. Hind coxa finely coriaceous, dorsally finely granulate with several rugae posteriorly. Hind femur entirely finely coriaceous. Hind tibia rather densely granulate with striation partly. First and second tergites entirely and third in basal 0.7 coarsely undulately striate with rugulosity between striae; third tergite smooth in medio-apical 0.3, rugulosecoriaceous in apicolateral 0.3. Fourth or fourth and fifth tergites very finely coriaceous. Remaining tergites smooth. Mesoscutum entirely with dense short semi-erect hairs. Hind tibia with rather long, rather sparse and semi-erect hairs dorsally, length of these hairs 0.7– 1.0× maximum width of hind tibia.

Colour. Head brownish yellow, yellow below. Mesosoma yellowish brown, sometimes propodeum medially and posteriorly and metanotum brown. Metasoma brown to reddish brown, sides of second and third tergites widely or very widely yellow; fourth to sixth tergites yellow laterally. Antenna yellow basally, distinctly infuscate toward apex. Palpi pale yellow. Tegulae yellow. Legs yellow, coxae paler, fifth tarsal segments brown. Fore wings entirely faintly infuscate. Pterostigma brown, yellow in basal 0.3 and apical 0.2–0.25.

Female. Unknown.

Discussion

This new species is similar to E. eous (Belokobylskij) but differs in the long first and second metasomal tergites ( Figure 43 View Figures 32–43 cf. Figure 54 View Figures 44–54 ), the long and weakly depressed mesosoma ( Figure 36 View Figures 32–43 cf. Figure 51 View Figures 44–54 ), the mesoscutum not arising highly above pronotum ( Figure 36 View Figures 32–43 cf. Figure 51 View Figures 44–54 ), the distinctly posteriorly convergent lateral depression of the second tergite ( Figure 43 View Figures 32–43 cf. Figure 54 View Figures 44–54 ), and the relatively long temple ( Figure 33 View Figures 32–43 cf. Figure 45 View Figures 44–54 ).
