Diagnosis.
Gena (Figs 4C View Figure 4 , 5A View Figure 5 ) evenly convergent posteriorly, with sparse uneven punctures. Clypeus smooth, shiny, subanterior margin with fine indistinct punctures. Propodeum (Fig. 5D View Figure 5 ) almost smooth, shiny, with indistinctly finely punctate. Area superomedia 0.6 × as wide as long. Tergites (Fig. 6A View Figure 6 ) shiny, with sparse fine punctures. First sternite reaching level of spiracle. Head and tergites 2-5 entirely black; Mesosoma and first tergite reddish to yellowish brown.
Description.
Female. Body length 6.8-7.0 mm. Fore wing length 4.5-4.8 mm. Ovipositor sheath length approximately 1.2-1.4 mm.
Head. Face (Fig. 4B View Figure 4 ) 2.2 × as wide as long, slightly convex medially, with weak punctures, distance between punctures mainly 0.5 to 1.5 × their diameter, sparser laterally. Anterior tentorial pit relatively large, almost circular. Median point of clypeal sulcus above level of line reaching lower margins of eyes. Clypeus smooth, 3.2 × as wide as long, evenly convex, with sparse indistinct punctures and long brown hairs; apical margin evenly arched forward. Mandible with fine punctures; upper tooth 3.3 × as long as lower tooth. Malar space 0.4 × as long as basal width of mandible. Gena (Figs 4C View Figure 4 , 5A View Figure 5 ) shiny, in dorsal view 0.3-0.4 × as long as width of eye, evenly convergent posteriorly, with sparse uneven punctures. Vertex (Fig. 4C View Figure 4 ) with distinct punctures, denser on stemmaticum than lateral and posterior portion. Postocellar line 0.8 × as long as ocular-ocellar line. Frons with dense punctures. Antenna with 23-26 flagellomeres. Flagellomeres 11 to 22(23) almost wider than long, ventral slightly flattened in ventral view. Ratios of lengths from first to fifth flagellomeres: 1.0:1.2:1.3:1.3:1.2. Occipital carina complete, reaching hypostomal carina almost near base of mandible.
Mesosoma. Dorsal and anterior portion of pronotum (Fig. 5C View Figure 5 ) shiny, media-posterior with indistinct oblique wrinkles, dorsal posterior portion with distinct fine punctures. Epomia long, strong, lower end reaching to anterior margin of pronotum, dorsal end almost reaching dorsal margin. Mesoscutum (Fig. 5B View Figure 5 ) shiny, lateral and anterior portions almost smooth, with sparse indistinct fine punctures, posteromedian portion with indistinct longitudinal wrinkles and fine punctures. Anterior portion of notaulus distinct. Scutoscutellar groove shiny, with indistinct longitudinal wrinkles. Scutellum with texture as lateral portion of mesoscutum, basal portion of lateral carina present anteriorly. Postscutellum transverse, smooth, with deep antero-lateral pits. Dorsal portion of mesopleuron (Fig. 5C View Figure 5 ) almost smooth, shiny, with sparse indistinct punctures; median portion with indistinct oblique wrinkles; lower slightly convex. Speculum indistinct. Metapleuron (Fig. 5C View Figure 5 ) evenly convex, with sparse fine punctures; lower portion with indistinct wrinkles. Juxtacoxal carina complete. Anterior portion of submetapleural carina distinctly convex. Ratio of length of hind tarsomeres from first to fifth: 6.9:2.6:1.9:1.0:1.8. Fore wing with vein 1cu-a opposite 1/M. Areolet pentagonal, lateral veins weakly convergent forward, receiving vein 2m-cu approximately at posterior 0.4. Hind wing vein 1-cu strongly inclivous, 3.0 × as long as cu-a. Propodeum (Fig. 5D View Figure 5 ) almost completely areolated, carinae strong; almost smooth, shiny, with sparse indistinct fine punctures. Area basalis almost triangular. Area superomedia 0.6 × as wide as long, receiving costula slightly before its middle. Apophysis distinct. Propodeal spiracle obliquely elliptic, approximate 3.2 × as long as wide.
Metasoma (Fig. 6A View Figure 6 ). First tergite (Fig. 6A, B View Figure 6 ) smooth, shiny, approximately 2.1 × as long as posterior width, median portion somewhat prismatic. Postpetiole evenly widened posteriorly, posterior width distinctly longer than its length. Latero-median carina weakly present; Dorso-lateral and ventro-lateral carinae present. First sternite reaching level of spiracle. Spiracle small, circular, located approximately at posterior 0.3 of first tergite. Tergites 2-4 (Fig. 6A View Figure 6 ) shiny. Second tergite smooth, strongly widened posteriorly, 0.6 × as long as posterior width, lateral with sparse indistinct fine punctures. Third tergite almost parallel laterally, with distinct even setae. Remaining tergites with dense short setae. Ovipositor sheath 0.8 × as long as hind tibia. Ovipositor (Fig. 6C View Figure 6 ) slightly compressed, subapical nodus indistinct, with weak notch; ventral valve with two weak teeth.
Coloration (Fig. 4A View Figure 4 ). Mainly black, reddish brown and white. Head black; maxillary and labial palpi yellowish white; mandible, scape and pedicel brownish yellow; dorsal profiles of flagellomeres 7-11 (12) white. Mesosoma reddish brown. Fore and middle coxae and all trochanters whitish yellow; remainder of fore and middle legs, hind coxa and subbase of tibia and tarsus predominantly yellowish brown; hind femur and posterior portion of tibia brownish black. First tergite reddish brown; tergites 2-6 black; tergites 7-8 white, blackish brown laterally. Pterostigma and wing veins brownish black.
Male. Body length 4.1-7.0 mm. Fore wing length 3.4-4.8 mm. Antenna with 22-25 flagellomeres. Flagellomeres 10-12 with tyloids. Face 2.1 × as wide as long. Clypeus 2.8 × as wide as long. Occipital carina reaching hypostomal carina above base of mandible. Area superomedia 1.0-1.2 × as wide as long, receiving costula at its anterior 0.3. Apophysis indistinct. Basal and ventral profiles of flagellomeres yellowish brown, dorsal profiles dark brown. Remainder of characteristics similar to female.
Etymology.
