Figs 1 View Figure 1 , 2 View Figure 2 , 3 View Figure 3
Diagnosis.
Gena (Figs 1C View Figure 1 , 2B View Figure 2 ) slightly convex medio-longitudinally, with dense punctures. Postocellar line 0.7 × as long as ocular-ocellar line. Areolet (Figs 1A View Figure 1 , 3B View Figure 3 ) receiving vein 2m-cu at posterior 0.2. Metapleuron with coarse dense punctures. Propodeum with area basalis distinctly wider than long, reversed trapezoidal. Area superomedia (Fig. 3C View Figure 3 ) wider than long. Tergites smooth. Posterior end of first sternite distinctly basad of spiracle. Flagellomeres 10-12 (13) of male with tyloids. Head, mesosoma and tergites 16 entirely black.
Description.
Female. Body length 8.6-10.1 mm. Fore wing length 6.8-8.0 mm. Ovipositor sheath length approximately 2.1-2.3 mm.
Head. Inner eye orbits divergent ventrally. Face (Fig. 1B View Figure 1 ) 2.0 × as wide as long, convex medially, with dense longitudinal punctures; dorsal margin with median small tubercle. Anterior tentorial pit relatively large, transversely elliptic. Median point of clypeal sulcus below line reaching ventral margins of eyes. Clypeus (Fig. 1B View Figure 1 ) shiny, distinctly convex, with sparse irregular punctures, 3.1 × as wide as long, apical margin weakly evenly arched forward, distinctly convex medially. Mandible (Fig. 2A View Figure 2 ) with transverse wrinkles, dense yellow brown setae and sparse punctures; teeth strong, upper tooth 1.5 × longer than lower tooth. Subocular sulcus indistinct. Malar space 0.5 × as long as basal width of mandible. Gena (Figs 1C View Figure 1 , 2B View Figure 2 ) in dorsal view 0.8-0.9 × as long as width of eye, slightly convex median-longitudinally, with more or less dense punctures, distance between punctures mainly 0.2 to 1.0 × their diameter. Vertex (Fig. 2B View Figure 2 ) and frons with texture as gena. Postocellar line 0.7 × as long as ocular-ocellar line. Antenna with 27-28 flagellomeres. Flagellomeres 11 to 25 slightly wider than long, slightly flattened in ventral profile. Ratios of lengths from first to fifth flagellomeres: 1.1:1.2:1.1:1.1:1.0. Occipital carina complete, reaching hypostomal carina distinctly above base of mandible.
Mesosoma. Pronotum (Fig. 2C View Figure 2 ) with yellow brown setae; dorsal posterior area shiny, with distinct punctures; lower portion with dense oblique transverse wrinkles. Epomia long, strong. Mesoscutum (Fig. 2D View Figure 2 ) shiny, with uneven punctures, postero-median portion with irregular longitudinal wrinkles. Notauli distinct anteriorly. Scutoscutellar groove steep, with distinct longitudinal wrinkles. Scutellum slightly convex, with irregular punctures and weak longitudinal wrinkles; lateral carina reaching almost to apex. Antero-lateral portion of postscutellum with deep concavity, posterior portion distinctly convex transversely. Mesopleuron (Fig. 3A View Figure 3 ) with irregular transverse wrinkles, median portion with uneven punctures; speculum small. Dorsal end of epicnemial carina closing anterior margin of mesopleuron, almost reaching to 0.5 distance to subtegular ridge. Metapleuron slightly convex, with dense punctures and yellow brown setae; juxtacoxal carina almost complete. Anterior portion of submetapleural carina strongly convex. Fore wing (Figs 1A View Figure 1 , 3B View Figure 3 ) with vein 1cu-a almost opposite 1/M. Areolet pentagonal, lateral veins convergent forwardly, receiving vein 2m-cu approximately at posterior 0.2. Postnervulus intercepted distinctly below middle. Hind wing vein 1-cu strongly inclivous, 3.0 × as long as cu-a. Ratio of length of hind tarsomeres from first to fifth: 6.4:2.8:2.0:1.0:2.5. Propodeum (Fig. 3C View Figure 3 ) completely areolated; apophysis distinct; area basalis reversed trapezoid, anterior half smooth, posterior with sparse punctures. Area superomedia wider than long, receiving costula slightly before its middle, with indistinct punctures. Remainder areas with indistinct punctures, irregular weak wrinkles and yellow brown setae. Propodeal spiracle relatively larger, obliquely elliptic, approximate 3.0 × as long as wide.
Metasoma (Fig. 3D View Figure 3 ). First tergite approximately 1.9 × as long as posterior width, smooth, shiny. Postpetiole distinctly widened posteriorly, posterior width approximately 1.3 × as its length, anterior and lateral portions with weak sparse punctures; latero-median carina indistinct; dorso-lateral and ventro-lateral carinae complete. Posterior end of first sternite distinctly basad of spiracle. Spiracle circular, small, located approximately at posterior 0.4 of first tergite. Tergites 2-4 shiny. Second tergite smooth, 0.5 × as long as posterior width, with sparse indistinct fine punctures. Third tergite 0.47 × as long as maximum width, with texture as second tergite, punctures denser than on second tergite. Fourth tergite with distinct fine punctures, denser than on third tergite. Ovipositor sheath 0.8 × as long as hind tibia. Ovipositor (Fig. 3E View Figure 3 ) compressed, with indistinct subapical nodus and weak notch; ventral valve with three weak teeth.
Coloration (Fig. 1A View Figure 1 ). Black, except the following: dorsal profiles of flagellomeres 7-12 white, ventrally slightly brownish black; apical portion of flagellum brown to dark brown. Median portion of mandible, maxillary and labial palpi darkish red. Fore and mid coxae brown to darkish brown; femora, basal portions of tibiae and tarsi predominantly dark brown. Hind coxa and trochanter brown; tarsomeres brownish black. Posterior margins of tergites 6-8 white medially.
Male. Body length 8.8-11.2 mm. Fore wing length 6.4-8.4 mm. Antenna with 26-28 flagellomeres. Flagellomeres 10-12 (13) with tyloids. Face 1.6 × as wide as long. Clypeus 2.6 × as wide as long. Median portion of mesopleuron smooth. Area superomedia of propodeum 2.0 × as wide as long. Apophysis indistinct. Black, except for following: Ventral profiles of flagellomeres 1-5, maxillary and labial palpi, fore tibia and first tarsomere yellowish brown. Flagellomeres 6-13, hind tarsomeres 1 apically and 2-4 white. Fore and mid femora reddish brown. Remainder of characteristics similar to female.
Etymology.
The specific name is derived from the area superomedia being wider.
