Head width 1.4× its median length. Head behind eye (dorsal view) weakly convex in anterior half, almost linearly narrowed in posterior half; transverse diameter of eye 1.5× as long as temple ( Figure 78 ). Ocelli small, in triangle with base 1.5× its sides. POL 1.7× Od, 0.7× OOL. Eye sparsely and shortly setose, 1.15× as high as broad. Malar space height 0.4× height of eye, 0.8× basal width of mandible ( Figure 79 ). Face width almost equal to height of eye and 1.2× height of face and clypeus combined. Clypeus with narrow lower flange. Clypeal suture distinct and complete. Hypoclypeal depression round, its width 0.6× distance from edge of depression to eye, 0.35× width of face ( Figure 77 ). Hypostomal flange indistinct. Antennae ( Figure 80 ) slender, filiform, more than 23-segmented (apical segments missing). Scapus 1.3× as long as its maximum width. First flagellar segment weakly curved outside, not flattened, about 5.0× as long as its apical width, slightly shorter than second segment. Subapical segments 3.8–4.0× as long as their width. Mesosoma . Length about 2× its height. Mesoscutum highly and almost perpendicularly raised above pronotum. Pronotal keel fine. Notauli deep in anterior half, shallow to almost indistinct in posterior half, crenulate. Prescutellar depression shallow, wide, with distinct median carina, striate with granulation, 0.3× as long as weakly convex scutellum. Subalar depression shallow, wide, rugose-areolate. Sternauli rather shallow, almost straight, narrow, very finely coriaceous, connected with prepectal carina anteriorly, running along almost entire length of lower part of mesopleura. Metapleural flange rather short, wide, almost pointed apically. Figures 77–87. Eodendrus petiolatus sp. nov. (77) Head, frontal view. (78) Head, dorsal view. (79) Head, lateral view.

Fore wing ( Figure 81 ) 3.6× as long as its maximum width. Radial vein arising from middle of pterostigma. Metacarpus 1.15× as long as pterostigma. Second radial abscissa almost 3.0× first abscissa, 0.5× the straight third abscissa, 1.4× first radiomedial vein. Second radiomedial cell almost 3.0× as long as its maximum width, 1.3× as long as brachial cell. First abscissa of medial vein distinctly S-shaped. Recurrent vein 5.0× second abscissa of medial vein. Distance from nervulus to basal vein almost equal to nervulus length. Brachial cell closed apically distinctly before recurrent vein. Hind wing ( Figure 82 ) 5.6× as long as wide. First abscissa of costal vein 0.5× second abscissa. First abscissa of mediocubital vein 0.5× second abscissa. Recurrent vein long, curved toward base of wing, unsclerotized, distinctly antefurcal. Legs. Hind coxa without basoventral tooth, its length 2× maximum width ( Figure 83 ). Hind femur 4.2× as long as wide ( Figure 84 ). Hind tibia with six short spines on apical outside margin ( Figure 85 ). Hind tarsus 1.1× as long as hind tibia. Basitarsus 0.6× as long as second to fifth segments combined. Second tarsal segment about 0.6× as long as basitarsus, 1.5× as long as fifth segment (without pretarsus). Metasoma. Metasoma ( Figure 87 ) 1.6× as long as head and mesosoma combined. First tergite weakly and linearly widened from base to apex, with long spiracular tubercles in basal 0.3 that are directed somewhat downwards. Acrosternite of first tergite 0.6× as long as tergite. Maximum width of first tergite 1.8× its minimum width; length 2.3× its apical width. Second tergite with shallow, curved, distinctly posteriorly convergent, light longitudinal lateral furrows; basal width of median area 1.6× its apical width; length of tergite 1.6× its basal width, 1.2× length of third tergite. Second suture shallow, but distinct, with very weak lateral bends. Ovipositor sheath 0.9× as long as body, 1.4× as long as metasoma, 1.3× as long as fore wing. Sculpture and pubescence. Vertex and frons finely transversely striate with granulation. Face distinctly transversely striate. Temple finely striate-coriaceous, almost smooth in lower 0.25. Mesoscutum striate-rugulose, with dense and fine granulation between striae. Scutellum finely granulate. Mesopleura rugulose-granulate in upper 0.7, almost smooth in lower 0.3. Metapleura entirely rugulose-reticulate. Propodeum densely rugulose-reticulate, with finely punctulate or almost smooth narrow and long lateral areas, without carinae and marginate areas. Hind coxae finely striate-granulate in dorsal half, almost smooth ventrally. First tergite striate, second and third tergites widely striate medially, striate-reticulate laterally. Remaining tergites smooth. Mesoscutum entirely with dense short semi-erect hairs. Hind tibia with rather short, dense and semi-erect hairs dorsally, length of these hairs 0.8–0.9× maximum width of hind tibia. Colour. Head and mesoscutum light reddish brown, remaining mesosoma and apex of metasoma reddish brown, most part of metasoma almost black. Antenna reddish brown, darkened toward apex, brownish yellow basally. Palpi yellow. Tegulae yellowish red. Legs brownish yellow. Ovipositor sheath black. Fore wings faintly infuscate. Pterostigma brown, pale yellow in basal 0.3 and apically. Male. Unknown. Discussion This new species is similar to E. eous (Belokobylskij) from the Russian Far East but differs in the narrow and long first tergite with long spiracular tubercles ( Figure 87 cf. Figure 54 ), the long acrosternite of the first metasomal segment, the long second tergite ( Figure 87 cf. Figure 54 ), the setose eye, and the slender hind femur ( Figure 84 cf. Figure 52 ). It differs from E. hoabinicus sp. nov. in the long and narrow first and second tergites ( Figure 87 cf. Figure 76 ), the relatively long temple ( Figure 78 cf. Figure 67 ), hind coxa ( Figure 83 cf. Figure 72 ) and hind femur ( Figure 84 cf. Figure 73 ), and the setose eyes. Distribution. China ( Guangxi ).
