Genus Eodendrus Belokobylskij, 1998 , stat. nov.

Type species. Dendrosotinus eous Belokobylskij, 1988 .

Description Head subcubical, its width 1.3–1.6× median length. Vertex distinctly convex. Ocelli arranged in triangle with base 1.3–1.5× its sides. Frons weakly concave and without median keel. Eyes glabrous or sparsely and very shortly setose. Occipital carina strong, not interrupted dorsally, usually obliterated ventrally for a short distance before reaching hypostomal carina. Malar suture absent. Clypeal suture complete. Hypoclypeal depression rather small and round. Postgenal bridge wide. Maxillary palpi six-segmented, labial palpi four-segmented; third segment of labial palpi not shortened. Scapus wide and rather short, without apical lobe. First flagellar segment weakly curved outside, usually not longer than second segment.

Mesosoma not depressed. Anterior pronotal lobe distinct and curved upwards. Pronotal keel absent or finely developed submedially. Propleural lobe distinct and wide. Mesonotum rather highly and usually almost perpendicularly raised above pronotum. Median lobe of mesonotum without anterolateral corners, distinctly protruding forward. Notauli rather wide, deep in anterior half, shallow or almost absent in posterior half. Prescutellar depression rather long and sculptured. Scuto-scutellar suture distinct. Scutellum weakly convex, with more or less distinct lateral carinae. Metanotum often with a short and usually pointed median tooth. Subalar depression shallow and wide. Mesopleural pit rather shallow and elongate. Sternauli rather deep, long, almost straight, running along entire length of lower part of mesopleura. Prepectal carina distinct and complete. Postpectal carina absent. Metapleural flange rather short and usually narrow. Propodeum without marginate areas; lateral tubercles and propodeal bridge absent.

Wings. Pterostigma of fore wing wide. Radial vein arising from or slightly behind middle of pterostigma. Radial cell not shortened. Both radiomedial veins present. Recurrent vein postfurcal. Nervulus distinctly postfurcal. Discoidal cell petiolate. Parallel vein interstitial. Brachial cell closed. Transverse anal veins absent. Hind wing with three hamuli. Nervellus present. Submedial cell short. First abscissa of mediocubital vein 0.5– 0.7× second abscissa. Recurrent vein present, strongly oblique toward base of wing. Medial cell rather wide. Radial vein arising from costal vein. Radial cell weakly narrowed toward apex, without additional transverse vein. Hind wing of male without stigma-like enlargement.

Legs. Fore and middle tibiae with sparse thick spines arranged in single row. Hind coxa rather large, usually without basoventral tooth. All femora without distinct dorsal protuberances. Hind femur distinctly thickened, elongate-oval. Hind tibia thickened, with five to seven spines on outer distal margin. Hind tibial spurs short.

Metasoma. First tergite subpetiolate or petiolate, more or less wide or rather narrow. Acrosternite (coarsely sclerotized and separated anterior part of sternite) in female (0.35) 0.4–0.6× and in male 0.25–0.3× as long as first tergite, its apical margin situated distinctly behind (female) or at level (male) of spiracles. Dorsope of first tergite distinct; basolateral lobes absent. Spiracular tubercles usually long and directed partly downwards, situated near basal 0.25–0.3 of tergite. Dorsal carinae present in basal 0.25–0.3. Second suture distinct, sometimes almost effaced medially, usually weakly laterally curved. Second tergite with more or less distinct, almost straight or curved, more or less strongly posteriorly convergent longitudinal furrows. Second and third tergites with separate laterotergites. Ovipositor usually a little shorter than body. Apex of ovipositor with two small dorsal nodes and finely serrate ventrally.

Distribution. East Palaearctic, Oriental, Afrotropical and Australian Regions. Diagnosis

This genus is similar to Dendrosotinus Telenga (distributed in the Palaearctic, Oriental and Afrotropical Regions) but differs in having the acrosternite of the first tergite of the female distinctly elongate and the second metasomal tergite with lateral and posteriorly convergent longitudinal furrows.
