Mesosoma coarsely sculptured; pronotum densely and coarsely areolate-rugose with one long and acute anterior tooth-like process on each lateroventral margin; propleuron polished and shiny with fine, deep and dense punctures on dorsal surface, fine, deep and scattered to dense on ventral surface (distance between punctures 2.0–3.0 × puncture diameters); prescutum triangular, wide, long, not concave to weakly concave toward apex, transverse carinate; mesoscutum mostly transverse-carinate, partly areolate-rugose posterior to notauli; anterior margin very slightly prominent and angulate (lateral view); notauli deep and wide; scutellum areolate-rugose on base, transverse-carinate medially, longitudinally carinate laterally; mesopleuron areolate-rugose, foveolate-rugulose on subalar area; metanotum longitudinally carinate; propodeum areolate-rugose, except anterior margin longitudinally carinate; venter of mesosoma transverse-carinate; fore wing with vein 2-rs+m short; coxa I polished and shiny, with very fine to fine, superficial to deep and dense punctures, deeper and denser basally; coxa II transverse-carinulate, with fine, deep and dense punctures medially on ventral surface; coxa III transverse-carinate on dorsal surface, transverse-carinulate-punctate on ventral surface (punctures coarse, deep and dense, distance between punctures about 2.0–3.0 × puncture diameters); inner spur of mid and hind tibia longer than outer spur; hind basitarsus 9.5 × longer than wide, and 1.2 × as tarsomeres 2–5; tarsal claw with four tooth-like processes. Setae: erect to semi erect, very short and dense on dorsal surface; mostly recumbent to semi erect, long and dense on sides and venter of mesosoma; erect to semi erect, long and dense on hind surface of propodeum; erect, long and dense on propleuron (setae length at most 0.6 × pretarsus length). Metasoma pyriform (lateral view), strongly compressed laterally; petiole very elongate, slender, 7.0 × longer than wide; segments 1 and 2 polished and shiny, impunctate; remaining tergites with fine, superficial and dense punctures; remaining sternites shiny, impunctate, with only a very fine microsculpture; S7 polished and punctate to longitudinally carinulate (distal half) with coarse, deep and very dense punctures; T8 very finely microreticulate, with fine, deep and scattered (on basal third) to dense punctures; ovipositor length equal to fore wing length. Setae: segments 1–2 and S3 glabrous, except a few very short and scattered setae on distal margin of T2; recumbent, short and dense on remaining tergites, especially on last two; semi erect, very short and scattered on medial part of S4– S6; erect, short and dense on S7. MALE ( paratype ). Length: 11.2 mm ; fore wing length: 7.9 mm . Colour, structure, and setae like ♀ , except: S1, metasomal segment 2 extensively reddish orange; wings without brown markings on cell B and obsolescent markings between cells SB and SD1; antenna length 0.7 × fore wing length; A3 3.5 × longer than wide; A4 6.0 × longer than wide, and 1.7 × longer than A3; A5 as long and wide as A4; A13 subcylindrical, with apex slightly acute, 4.7 × longer than wide; hind basitarsus 10.4 × longer than wide. Variation . Examined 2♀ , 2♂ . Length: 9.2–12.8 mm ( ♀ ); 9.7–11.2 ( ♂ ); fore wing length: 7.6–9.0 mm ( ♀ ); 7.4– 7.9 mm ( ♂ ); ovipositor 1.0–1.1 × fore wing length. The irregular brown spots on cells B, SB, SD1 are obsolescent to absent in the males paratypes ; the metasoma is lighter in the female paratype and especially in the two males paratypes , with irregular reddish-orange markings on S1, and partly on segments 2–4.
