description: Gelanes dentator Khalaim & Lee, sp. nov.
(Figs 2, 6, 14, 18, 27–29)
Description. Female (holotype).
Body length 2.7 mm. Fore wing length 2.5 mm (Fig. 27).
Color: head, mesosoma and first tergite brown (holotype decoloured). Metasoma pale brown. Palpi, mandible (teeth reddish black), lower 0.8 of clypeus, tegula and legs (coxae brownish) yellow. Antenna brownish yellow. Pterostigma pale brown.
Morphology. Head: in dorsal view, roundly narrowed behind eyes (Fig. 29); temple 0.78 times as long as eye width. Upper tooth of mandible distinctly longer than lower tooth. Clypeus broad, smooth in lower part and finely punctate in upper part. Malar space about 0.8 times as long as basal width of mandible. Flagellum of antenna filiform, with 17 flagellomeres, moderately slender basally, with subapical flagellomeres slightly elongate (Fig. 2). Face and frons very finely granulate, impunctate, dull. Temple smooth and shining, without distinct punctures (Fig. 6).
Mesosoma: notaulus absent. Mesoscutum finely punctate on more or less smooth background. Foveate groove of mesopleuron weak, moderately broad, with fine transverse wrinkles. Mesopleuron smooth, impunctate or with very indistinct punctures. Basal area of propodeum wide, rectangular, about 1.7 times as long as broad (sometimes indistinct), almost 0.6 times as long as apical area. Dorsolateral area smooth, very indistinctly punctate. Propodeal spiracle small, distance between spiracle and pleural carina equal to half diameter of spiracle. Apical area flat, uneven. Apical longitudinal carinae complete, reaching transverse carina anteriorly.
Wings: fore wing with second recurrent vein postfurcal, unpigmented in anterior 0.7 (Fig. 28). Intercubitus moderately thick, somewhat longer than abscissa of cubitus between intercubitus and second recurrent vein. First abscissa of radius almost as long as width of pterostigma. Metacarp far short apex of fore wing. Postnervulus intercepted far below middle. Hind wing with nervellus subvertical.
Metasoma: first tergite 2.4 times as long as posteriorly broad, depressed, with moderately large glymma before its middle, dorsally smooth, petiole distinctly striate laterally before glymma. Second tergite about as long as anteriorly broad. Thyridial depression slightly elongate. Ovipositor moderately robust, upcurved, widened apically, with shallow dorsal subapical depression and two more or less distinct rounded teeth before and behind this depression; sheath about 2.7 times as long as first tergite and about 1.8 times as long as hind tibia.
Male. Unknown.
Material examined. [Holotype] South Korea: 1♀, [GG] Namyangju-si Wabu-eup Dogong-ri San84 Korea Univ. Forestry experiment station SUGWAN-D, 37°34'55"N 127°13'43"E, 20.V.1986, J.W. Lee.
Distribution. South Korea (new record).
Biology. Flight period in May. Host unknown.
Etymology. The species name refers to the denticulate apex of the ovipositor.
Remarks. The new species resembles G. bidentatus Khalaim as both have similar shape of the ovipositor and first tergite dorsally smooth, but differs from this species by the shorter ovipositor, larger basal area of propodeum and shorter distance between propodeal spiracle and pleural carina.
