Eye very weakly emarginated opposite antennal sockets, 1.3 times as high as broad. Malar space 0.65 times height of eye, 1.6 times basal width of mandible. Face width almost equal to height of eye and equal to height of face and clypeus combined. Upper margin of clypeus situated below line on lower level of eyes. Hypoclypeal depression width 0.6 times distance from edge of depression to eye, 0.35 times width of face. Vertex distinctly convex. Head below eyes (front view) distinctly and almost linearly narrowed. Antennae rather slender, filiform, 25-segmented, 0.9 times as long as body. Scapus 1.7 times as long as its maximum width. First flagellar segment 3.3 times as long as its apical width, 1.1 times as long as second segment. Penultimate segment 2.4 times as long as its width, 0.6 times as long as first segment, 0.85 times as long as apical segment.

MESOSOMA. Length 1.9 times its height. Pronotal carina distinct, medial distances from carina to both sides of pronotum subequal. Mesoscutum 0.9 times as long as maximum width. Notauli entirely deep, rather wide, coarsely crenulate. Prescutellar depression deep, rather long, distinctly and linearly curved postero-laterally, distinctly rugulose, 0.3 times as long as the weakly convex scutellum. Sternaulus (precoxal furrow) rather deep, wide, weakly curved, distinctly and densely crenulate. Prepectal carina without widened lobes opposite fore coxae. Subalar depression rather shallow, more or less narrow, distinctly crenulate and almost smooth between crenulae. Metapleural lobe long, rather narrow, rounded apically, with dense pubescence posteriorly. Mesopleural suture entirely and coarsely crenulate.

WINGS. Fore wing 3.8 times its maximum width. Metacarpus (1-R1) 1.2 times as long as pterostigma. First radial abscissa (r) forming very obtuse angle with second abscissa (3-SR). Second radial abscissa (3-SR) 3.3 times as long as first abscissa (r), 0.4 times as long as straight third abscissa (SR1), 1.15 times as long as first radiomedial vein (2-SR). Second radiomedial (submarginal) cell not widened distally, 2.6 times as long as wide, 1.6 times as long as brachial (subdiscal) cell. First medial abscissa (1-SR+M) weakly sinuate. Discoidal (discal) cell 2.3 times as long as its maximum width. Mediocubital vein (M+CU1) almost straight. Distance between nervulus (cu-a) and basal (1-M) vein almost equal to nervulus (cu-a) length. Brachial (subdiscal) cell narrow, almost perpendicularly closed distinctly before level of recurrent vein (m-cu); posterior bulla present; posterior abscissa of anal vein (2-1A) (behind brachial vein (CU1b)) indistinct. Hind wing 5.4 times as long as wide. First costal abscissa (C+SC+R) 0.8 times as long as second abscissa (1-SC+R). First abscissa of mediocubital vein (M+CU) 0.7 times as long as second abscissa (1-M). Recurrent vein (m-cu) fine, unsclerotised, curved, weakly antefurcal.

LEGS. Hind coxa 1.5 times as long as wide (with tubercle). Hind femur with fine dorsal protuberance, length of femur 3.8 times maximum width. Hind tarsus 0.9 times as long as hind tibia. Hind basitarsus 0.8 times combined length of second–fifth segments. Second tarsal segment 0.4 times as long as basitarsus, 2.0 times as long as fourth segment, 1.3 times as long as fifth segment (without pretarsus).

METASOMA. Length 1.1 times as long as head and mesosoma combined. First tergite with distinct but short subbasal lateral processes. Maximum width of first tergite 3.3 times its basal width; its length almost equal to apical width, 1.4 times length of propodeum. Second tergite with shallow and weakly curved subposterior transverse furrow indistinctly separated narrow apical area; median length of apical area about 0.4 times length of remaining part of tergite. Median length of second tergite 0.55 times its basal width, 1.35 times length of third tergite. Second suture rather wide, almost straight. Fifth tergite weakly convex in posterior margin, without median emargination and postero-ventral lobes. Fifth tergite 1.4 times as long as fourth tergite, 1.7 times as long as third tergite. Ovipositor sheath 0.55 times as long as metasoma, 0.8 times as long as mesosoma, 0.45 times as long as fore wing.

SCULPTURE AND PUBESCENCE. Vertex entirely densely granulate, without striae or rugae; frons coarsely and irregularly densely rugose, with granulation medio-posteriorly; face densely and rather distinctly granulate, finely granulate to almost smooth medially; temple densely granulate with rugose posteriorly, below finely coriaceous to smooth. Mesoscutum entirely densely and distinctly granulate, with distinct rugosity on median lobe and laterally, with long coarse striae in medio-posterior half of mesoscutum. Scutellum densely and distinctly granulate. Mesopleuron densely and coarsely granulate-rugose, finely and widely coriaceous medially, smooth below sternaulus. Metapleuron coarsely densely rugosereticulate. Propodeum with distinctly delineated and densely granulate-rugose basolateral areas, with three longitudinal median carinae in basal half, coarsely areolate in posterior half.
