Setae: erect, long and scattered on vertex; semi erect to erect, long and dense on temple (length of setae 0.8–0.9 × diameter of an ocellus); erect, long and scattered to dense on upper frons; recumbent, long and dense on lower frons and clypeus; recumbent, short and dense on malar area.

Mesosoma coarsely sculptured; pronotum mostly areolate-rugose, densely foveolate-punctate above lateroventral margin, with one well-developed anterior tooth-like process on lateroventral margin; propleuron polished and shiny with fine, deep and dense punctures on dorsal surface, fine, deep and dense on ventral surface (distance between punctures 2.0 × puncture diameters); prescutum triangular, wide, long, not concave to weakly concave toward apex, transverse carinate; mesoscutum transverse-carinate to areolate-rugose posterior to notauli; anterior margin not prominent, rounded (lateral view); notauli superficial and wide; scutellum mostly areolate-rugose, transverse-carinulate to confused-rugulose toward middle; mesopleuron areolate-rugose, confused-rugulose on subalar area; metanotum longitudinally carinate, except middle, areolate-rugose; propodeum areolate-rugose, except anterior margin longitudinally carinate; venter of mesosoma transverse-carinate; fore wing with vein 2- rs+m short; coxa I dull, obliquely strigate dorsally, irregularly rugose-punctate ventrally, with fine to coarse, deep and dense punctures; coxa II transverse-carinate; coxa III transverse-carinate on dorsal surface, transverse-carinulate on ventral surface with fine to coarse, deep and dense punctures medially (distance between punctures about 1.0 × puncture diameters); spurs of mid tibia subequal length; inner spur of hind tibia longer than outer spur; hind basitarsus 8.8 × longer than wide, and 1.2 × as tarsomeres 2–5; tarsal claw with four tooth-like processes. Setae: erect to semi erect, 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 elongate, slender, 3.1 × longer than wide; segments 1 and 2 mostly polished and shiny, with a few or scattered fine and superficial punctures on T2 and S2; remaining segments with fine, superficial and dense punctures, except laterally on tergites and sternites; S7 polished and shiny, punctate, punctures fine to coarse, deep and dense; T8 very finely microreticulate, with fine, superficial and dense punctures, except base; ovipositor 0.9 × longer than fore wing length. Setae: segments 1 and 2 and S3 glabrous; recumbent, very short and dense only on medial part of remaining tergites and sternites.

MALE unknown.
