description: Gelanes provectus Balueva & Lee, sp. nov.
(Figs 4, 10, 36–38)
Description. Female (holotype).
Body length 2.5 mm. Fore wing length 2.23 mm (Fig. 36).
Color: head and mesosoma dark brown to black. Palpi, mandible (teeth blackish), lower 0.8 of clypeus, tegula and legs (hind coxa sometimes brownish basally) brownish yellow. Antenna more or less uniformly dark brown or black. Pterostigma pale brown. Metasomal predominantly dark brown.
Morphology. Head: in dorsal view, roundly narrowed behind eyes; temple 0.63 times as long as eye width. Upper tooth of mandible about as long as lower tooth. Clypeus flat in lower 0.7–0.8, smooth, punctate in upper 0.2–0.3 and with few punctures near its lower margin. Malar space slightly shorter than basal width of mandible. Flagellum of antenna more or less filiform, with 16–17 flagellomeres (16 flagellomeres in holotype); flagellomeres 2 and 3 about 1.4–1.8 times as long as broad, subapical flagellomeres 1.1–1.3 times as long as broad. Face and frons finely punctate (punctures on face sometimes indistinct) on more or less smooth, dull background. Vertex and temple smooth, finely and sparsely punctate.
Mesosoma: notaulus as weakly impressed and more densely granulate area. Mesoscutum finely punctate, smooth between punctures. Foveate groove of mesopleuron sharp, narrow and crenulate, about half as long as mesopleuron, slightly upcurved anteriorly. Mesopleuron smooth and shining, finely punctate (sometimes impunctate centrally). Basal area of propodeum distinctly widened anteriorly (Fig. 10), about half as long as apical area. Dorsolateral area smooth, usually finely and sparsely punctate. Propodeal spiracle small, distance between spiracle and pleural carina equal to 1.0–1.5 diameters of spiracle. Apical area flat, uneven. Apical longitudinal carinae sometimes indistinct.
Wings: fore wing with second recurrent vein postfurcal, unpigmented in anterior 0.6–0.8. Intercubitus moderately thick, usually as long as abscissa of cubitus between intercubitus and second recurrent vein, sometimes slightly longer or shorter (rather short in holotype). First abscissa of radius somewhat longer than width of pterostigma. Metacarp far short apex of fore wing (Fig. 36). Postnervulus intercepted far below middle. Hind wing with nervellus vertical.
Metasoma: first tergite about 2.6 times as long as posteriorly broad, depressed, with moderately large glymma before its middle; petiole coarsely striate laterally, smooth or slightly uneven dorsally; postpetiole smooth. Second tergite about 1.1 times as long as anteriorly broad. Thyridial depression triangular, slightly elongate. Ovipositor slender, upcurved, with apex lanceolate, with very small and narrow notch dorsally and fine teeth ventrally (Fig. 38); sheath 2.2–2.5 (2.35 in holotype) times as long as first tergite and about 1.9 times as long as hind tibia.
Male. Males of this species are probably mixed with males of C. cuspidatus since coloration of antenna and shape of basal area of propodeum cannot be used to distinguish males of these species. Some males were identified as G. cuspidatus, and other material (62 specimens) belong to the complex of “ cuspidatus + provectus ”. We do not include males of the type series of this species.

Kim.
Distribution. South Korea (new record), Russia (Primorskiy reg.).
Biology. Flight period from April to June. Host unknown.
Etymology. From the Latin “ provectus ” (advanced, late, elderly).
Remarks. The new species is closely related to G. cuspidatus as both have similar lanceolate apex of ovipositor with small dorsal notch (Fig. 38), sharp foveate groove of mesopleuron, clypeus with transverse crease in its lower part, and finely punctate face and frons. It differs from G. cuspidatus by having uniformly dark brown or black antenna (in G. cuspidatus scape and pedicel more or less yellowish, distinctly paler than flagellum), widened anteriorly basal area of propodeum, and much shorter ovipositor.
