Mesosoma coarsely sculptured; pronotum mostly areolate-rugose, foveolate-punctate above lateroventral margin, with two well-developed, wide anterior and posterior tooth-like processes on each lateroventral margin, posterior one less developed than anterior; propleuron polished and shiny with coarse, deep and dense punctures on dorsal surface, fine, deep and dense on ventral surface (distance between punctures 2.0–3.0 × puncture diameters); prescutum triangular, wide, long, not concave to concave toward apex, coarsely punctate basally to transverse carinate apically; mesoscutum transverse-carinate to areolate-rugose on anterior lobe and posterior to notauli; dorsally convex and slightly prominent; anterior margin moderately prominent, angulated (lateral view); notauli deep and wide; scutellum areolate-rugose; mesopleuron areolate-rugose, except a very restricted part of subalar area, polished with coarse, superficial and dense punctures; metanotum longitudinally carinate, except medially, areolaterugulose; propodeum areolate-rugose, except anterior margin longitudinally carinate; venter of mesosoma mostly transverse-carinate with a wide polished and punctate submedial “stripe” on each side; fore wing with vein 2-rs+m short; coxa I polished with fine, superficial and dense punctures; coxa II transverse-carinulate dorsally, polished to transverse-rugulose ventrally with coarse, deep and dense punctures; coxa III transverse-carinate dorsally, mostly polished on ventral surface, except base transverse-rugose, with fine to coarse, superficial to deep and dense punctures (distance between punctures 1.0–2.0 × puncture diameters); inner spur of mid and hind tibia longer than outer spur; hind basitarsus 8.6 × longer than wide, and 0.9 × as tarsomeres 2–5; tarsal claw with six tooth-like processes. Setae: erect, short to long, and dense on dorsal surface; mostly erect, long (especially on pronotum) and dense on sides and ventral part of mesosoma; erect, long and dense on hind surface of propodeum; erect, long and dense on propleuron (setae length at most 0.7–0.8 × pretarsus length).

Metasoma pyriform (lateral view), moderately compressed laterally; petiole elongate, slender, 2.9 × longer than wide; T1 and S1, S2 polished and shiny; T2 mostly punctate except base, punctures fine, deep and dense; remaining tergites with fine, deep and dense punctures, sternites with scattered to dense punctures; S7 polished with fine to coarse, deep and dense punctures; T8 polished with fine, superficial and dense punctures; ovipositor 0.9 × fore wing length. Setae: T1 and S1, S2 glabrous; recumbent, short and scattered to dense on most of T2, except base; recumbent, short and dense on remaining tergites; recumbent to semi erect, short and dense medially on remaining sternites.
