Malar space height 0.4–0.5× height of eye, 0.8–1.0× basal width of mandible ( Figure 68 View Figures 66–76 ). Face width almost equal to height of eye and 1.1–1.2× height of face and clypeus combined. Clypeus with narrow lower flange. Clypeal suture distinct and complete. Hypoclypeal depression round, its width 0.5– 0.6× distance from edge of depression to eye, 0.3–0.4× width of face ( Figure 66 View Figures 66–76 ). Hypostomal flange narrow. Antennae ( Figure 69 View Figures 66–76 ) rather slender, filiform, more than 26- segmented (apical segments missing). Scapus 1.2–1.3× as long as its maximum width. First flagellar segment weakly curved outside, not flattened, 5.0–5.5× as long as its apical width, 0.85× as long as second segment. Subapical segments about 4.5× as long as their width.

Mesosoma . Length 2.2× its height. Mesoscutum highly and perpendicularly raised above pronotum. Pronotal keel rather distinct. Notauli deep in anterior half, shallow in posterior half, coarsely crenulate. Prescutellar depression rather shallow, with three carinae, almost smooth, 0.4× as long as scutellum. Subalar depression shallow, wide, striate-rugulose. Sternauli rather deep, straight, narrow, almost smooth, connected with prepectal carina anteriorly, running along almost entire length of lower part of mesopleura. Metapleural flange rather short, wide, almost pointed apically.

Wings. Fore wing ( Figure 70 View Figures 66–76 ) 3.4–3.7× as long as its maximum width. Radial vein arising from or shortly behind middle of pterostigma. Metacarpus 1.1–1.2× as long as pterostigma. Second radial abscissa 2.5–3.5× first abscissa, 0.5× the straight third abscissa, 1.2–1.4× first radiomedial vein. Second radiomedial cell 2.8–3.0× as long as its maximum width, 1.3× as long as brachial cell. First abscissa of medial vein very weakly S-shaped. Recurrent vein about 3.0× second abscissa of medial vein. Distance from nervulus to basal vein 1.0–1.3× nervulus length. Brachial cell closed apically distinctly before recurrent vein. Hind wing ( Figure 71 View Figures 66–76 ) 5.5× as long as wide. First abscissa of costal vein 0.5–0.6× second abscissa. First abscissa of mediocubital vein 0.5× second abscissa. Recurrent vein short, curved toward base of wing, unsclerotized, distinctly antefurcal.

Legs. Hind coxa without basoventral tooth, its length 1.8–2.0× maximum width ( Figure 72 View Figures 66–76 ). Hind femur 3.0–3.3× as long as wide ( Figure 73 View Figures 66–76 ). Hind tibia with five short spines on apical outside margin ( Figure 74 View Figures 66–76 ). Hind tarsus 1.1× as long as hind tibia. Basitarsus thickened, 0.5× as long as second to fifth segments combined. Second tarsal segment 0.6–0.65× as long as basitarsus, 1.3–1.5× as long as fifth segment (without pretarsus).

Metasoma. Metasoma ( Figure 76 View Figures 66–76 ) almost as long as head and mesosoma combined. First tergite distinctly and linearly widened from base to apex, with long spiracular tubercles in basal 0.25 that are directed somewhat downwards. Acrosternite of first tergite about 0.5× as long as tergite. Maximum width of first tergite 2.3× its minimum width; length 1.6– 1.7× its apical width. Second tergite with rather distinct, shallow, almost straight, posteriorly convergent, lateral longitudinal light furrows; basal width of median area 1.8– 2.2× its apical width; length of tergite 1.0–1.2× its basal width, 1.3–1.5× length of third tergite. Second suture shallow, but distinct, with very weak lateral bends. Ovipositor sheath 0.7–0.9× as long as body, 1.3–1.8× as long as metasoma, 0.9–1.1× as long as fore wing.

Sculpture and pubescence. Vertex and frons distinctly and densely granulate with fine transverse striation in part. Face distinctly transversely striate with dense granulation between striae. Temple distinctly and obliquely striate-coriaceous, almost smooth in lower 0.25. Mesoscutum densely rugulose-granulate, rather widely rugose-reticulate in medioposterior 0.7. Scutellum distinctly and densely granulate. Mesopleura rugulosegranulate in upper 0.3, granulate or granulate-coriaceous in median 0.3, almost smooth below sternauli. Metapleura entirely and coarsely rugulose-reticulate. Propodeum densely rugulosereticulate, rather sparsely and distinctly punctulate in long lateral areas, sometimes with fine median carina in basal 0.3, without marginate areas. Hind coxae distinctly and sparsely striate with dense granulation in dorsal half and coriaceous laterally. Hind femur distinctly and densely granulate, finely granulate below. Hind tibia densely granulate, coriaceous in lower half. First and second tergites densely striate, with dense reticulation between striae. Third tergite striate in mediobasal 0.25, densely granulate basolaterally, coriaceous for most part, smooth medioapically. Remaining tergites smooth. Mesoscutum entirely with dense short semi-erect hairs. Hind tibia with rather short, rather dense and semi-erect hairs dorsally, length of these hairs 0.5–0.8× maximum width of hind tibia.

Colour. Head brownish yellow. Mesosoma light reddish brown, prescutellar depression, axillae, metanotum, below part of metapleura and propodeum medially and posteriorly or entirely distinctly infuscate to black. Metasoma dark reddish brown, second and third tergites in furrows and suture and around its light reddish brown, second tergite with rather large yellow or brownish yellow lateroapical spots; apex of metasoma brownish yellow. Sometimes body almost entirely light reddish brown. Antenna dark reddish brown, almost black apically, two basal segments yellow. Palpi yellow. Tegulae yellowish brown. Legs brownish yellow; hind leg light reddish brown, trochanter and basal 0.2 of tibia pale yellow; rarely legs entirely yellow. Ovipositor sheath black, dark brown basally. Fore wings faintly infuscate. Pterostigma brown, pale yellow in basal 0.4 and apically.

Male. Unknown.

Discussion

This new species is similar to E. petiolatus sp. nov. but differs in the relatively short temple ( Figure 67 View Figures 66–76 cf. Figure 78 View Figures 77–87 ), the thick hind femur ( Figure 73 View Figures 66–76 cf. Figure 84 View Figures 77–87 ), the wide and short first metasomal tergite ( Figure 76 View Figures 66–76 cf. Figure 87 View Figures 77–87 ), and the short second tergite ( Figure 76 View Figures 66–76 cf. Figure 87 View Figures 77–87 ). E. hoabinicus sp. nov. is similar also to E. eous (Belokobylskij) but differs in the long acrosternite of the first tergite, the large spiracular tubercle of the first tergite ( Figure 76 View Figures 66–76 cf. Figure 54 View Figures 44–54 ), the relatively short temple ( Figure 67 View Figures 66–76 cf. Figure 45 View Figures 44–54 ), the first flagellar segment being distinctly shorter than the second segment ( Figure 76 View Figures 66–76 cf. Figure 87 View Figures 77–87 ), and the distinctly convergent posteriorly furrows of the second tergite ( Figure 76 View Figures 66–76 cf. Figure 54 View Figures 44–54 ).
