Colour blackish except: mandible with distal half dark reddish; maxillo-labial complex dark reddish; antenna dark brown except A1 reddish orange; fore and mid legs brownish, with tibiae and tarsi lighter and coxae dark brown; hind leg dark brown except coxa; fore wing largely infuscate especially basally and below stigma, with apex lighter and medial part hyaline (basal half of cells SM1 and D1); hind wing slightly infuscate; metasoma dark brown with segments 1–2 partly dark red orange. Setae: mostly light brown, goldish on mandible.

Head, from above 1.3 × wider than long, shiny; occipital margin deeply grooved medially; temple, from above, well developed, rounded; occipital carina narrow, 0.2–0.3 × diameter of an ocellus, obsolescent medially; POL:OOL= 1.3; ocellar area 2.5 × wider than long; vertex and temple with fine, deep and scattered to dense punctures (distance between punctures 2.0–3.0 × puncture diameters); frons with fine, deep and dense punctures (distance between punctures 1.0 × puncture diameters); clypeus with coarse, deep and dense punctures on basal half, otherwise indistinctly punctate; malar area indistinctly punctate, with a few coarse scattered punctures apically; occipital area with fine, deep and scattered punctures (distance between punctures 3.0–5.0 × puncture diameters); antenna 0.7 × as long as fore wing length; A3 3.4 × longer than wide; A4 4.3 × longer than wide, and 1.4 × longer than A3; A5 4.1 × longer than wide, and 1.3 × longer than A3. Setae: erect, long and scattered on vertex; semi erect, long and scattered on temple (length of setae 1.0 × diameter of an ocellus); erect, long and dense on upper frons; recumbent, long and dense on lower frons and clypeus; recumbent, long and dense on malar area.

Mesosoma coarsely sculptured; pronotum mostly areolate rugose to foveolate with two well-developed anterior and posterior tooth-like processes on each lateroventral margin; propleuron polished and shiny with coarse, deep and dense punctures on most of dorsal surface, fine, deep and dense on ventral surface (distance between punctures 1.0–2.0 × puncture diameters); prescutum triangular, very long, mostly concave (except base), transverse rugose except base coarsely punctate; mesoscutum transverse-carinate to areolate-rugose (posterior to notauli) with two well-developed anterolateral lobe-like processes; anterior margin prominent, slightly pointed (lateral view); notauli deep and wide; scutellum areolate-rugose; mesopleuron areolate-rugose, except subalar area, polished with coarse, superficial and dense punctures; metanotum longitudinally carinate; propodeum coarsely areolate-rugose, except anterior margin longitudinally carinate; venter of mesosoma mostly transverse-carinate; fore wing with vein 2-rs+m short (obliterate); coxa I polished, very weakly punctate; coxa II transverse-carinate on dorsal surface, polished to transverse strigate and punctate on ventral surface; coxa III transverse-carinate on dorsal surface, polished to microreticulate and punctate on ventral surface, punctures fine to coarse, superficial and dense (distance between punctures about 1.5 × puncture diameters); inner spur of mid and hind tibia slightly longer than outer spur; hind basitarsus 10.2 × longer than wide (tarsomeres 4–5 missing); tarsal claw with six tooth-like processes. Setae: erect or semi erect, short and scattered on dorsal surface; erect to semi erect, long and dense on pronotum; mostly recumbent, short and dense on sides and venter of mesosoma; erect, long and dense on hind surface of propodeum; erect, long and dense on propleuron (setae length about 0.6 × pretarsus length).

Metasoma pyriform (lateral view), strongly compressed laterally; petiole elongate, slender, 2.1 × longer than wide; segments 1 and 2 mostly polished and shiny except sides of T2 and most of S2 with fine, superficial and scattered punctures; remaining segments with very fine, superficial and dense punctures; S7 polished punctate, punctures fine (distally) to coarse, deep and dense (distally) to very dense; T8 polished with fine, deep and dense punctures; ovipositor 0.9 × longer than fore wing length. Setae: segments 1 and 2 mostly glabrous except apical and sides of T2 (semi erect, short and very scattered); recumbent, short and dense on remaining segments.

MALE unknown.
