Gelanes protritus Kim & Lee , sp. nov.

(Figs 8, 11, 16, 33–35)

Description. Female (holotype).

Body length 2.4 mm. Fore wing length 2.2 mm ( Fig. 33 ).

Color: Head brownish black; clypeus, mandible (teeth reddish black) and palpi yellow. Antenna dark brown, scape and pedicel ventrally yellow. Mesosoma and metasoma brown to dark brown; tegula yellow. Pterostigma pale brown. Legs yellow.

Morphology. Head: in dorsal view, roundly narrowed behind eyes; temple 0.7 times as long as eye width. Upper tooth of mandible somewhat longer than lower tooth. Clypeus flat and smooth in lower 0.7–0.8, very finely granulate and punctate in upper 0.2–0.3, and with few punctures near its lower margin. Malar space about 0.8 times as long as basal width of mandible. Flagellum of antenna filiform or very weakly clavate apically, with 16–18 flagellomeres (16 flagellomeres in holotype); all flagellomeres elongate; second flagellomere usually smaller than flagellomeres 1 and 3. Face and frons finely granulate, dull, without distinct punctures. Vertex and temple smooth, indistinctly punctate.

Mesosoma : notaulus weak or absent. Mesoscutum finely punctate, smooth between punctures. Foveate groove weak and shallow, about half as long as mesopleuron, horizontal or slightly upcurved anteriorly(Fig. 8). Mesopleuron smooth and shining, sometimes very finely punctate centrally. Propodeum with basal keel or rarely with very narrow basal area (Fig. 11); basal part of propodeum about 0.4 times as long as apical area. Dorsolateral area smooth and shining. Propodeal spiracle small, distance between spiracle and pleural carina subequal to one diameter of spiracle ( Fig. 35 ). Apical area flat, uneven. Apical longitudinal carinae usually complete, reaching transverse carina anteriorly.

Wings: fore wing with second recurrent vein postfurcal, unpigmented in anterior 0.6. Intercubitus moderately thick, about as long as abscissa of cubitus between intercubitus and second recurrent vein. First abscissa of radius as long as or somewhat shorter than width of pterostigma. Metacarp far short apex of fore wing ( Fig. 33 ). Postnervulus intercepted far below middle. Hind wing with nervellus vertical or slightly reclivous.

Metasoma: first tergite 2.3 times as long as posteriorly broad, depressed, with moderately large glymma before its middle; petiole coarsely striate laterally before glymma, dorsally smooth in basal half and striate posteriorly; postpetiole smooth. Second tergite somewhat transverse. Thyridial depression very short, strongly transverse. Ovipositor with apex rather thick, with wide dorsal subapical depression and usually with two more or less distinct teeth before and behind this depression; sheath about 2.9 times as long as first tergite and about 2.1 times as long as hind tibia.

Male. Malar space shorter. First and second metasomal flagellomeres longer. Otherwise similar to female.

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; [Paratypes] South Korea: 14♀, 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; 6♀, ditto, SUGWAN-A, 37°34'55"N 127°13'15"E, 19.IV.1986, J.W. Lee; 2♀, ditto, 37°34'55"N 127°13'15"E, 29.V.1987, J.W. Lee.

Distribution. South Korea (new record).

Biology. Flight period in May. Host unknown.

Etymology. From the Latin “ protritus ” (common, trite, commonplace).

Remarks. The new species resembles the European G. carinatus Khalaim & Blank as both have propodeum with basal keel or rarely with a pair of very close longitudinal carinae, but it differs from this species by shorter ovipositor (sheath about 2.8 times as long as first tergite in G. protritus and 3.4 times in G. carinatus ), deeper and sharper foveate groove of mesopleuron (in G. carinatus it is as granulate or shallowly wrinkled area, more or less reaching base of mid coxa) and flagellum with 16–17 flagellomeres (18 flagellomeres in G. carinatus ).
