Head
. Antenna 34-segmented. Terminal flagellomere acuminate, 2.3× as long as wide. Medial flagellomere 1.5× as long as wide. Scape shorter ventrally than dorsally, anteriorly depressed (
Fig. 2
B). First flagellomere 2.4× as long as wide, 1.2 and 1.4× as long as second and third flagellomeres respectively. Hypoclypeal depression dorsally bordered medially by a transverse carina (
Figs 1
B, 2C). Clypeus clearly separated from face by a shallow transverse groove (
Figs 1
B, 2C). Dorsal clypeal carina indistinct. Tentorial pit deep. Face rugose except posterior 1/3 transversely striate, setose with a medial longitudinal groove in anterior half (
Fig. 2
C). Malar suture distinct. Eye glabrous. Height of clypeus: inter-tentorial distance: tentorio-ocular distance= 2.9: 6.6: 4. Height of eye: width of face: width of head= 7.5: 6.4: 14. POL: diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 3.25: 3.5: 7.25. Frons with medial longitudinal groove, faintly transversely striate (
Fig. 2
A). Vertex rugose with medial longitudinal groove behind posterior ocelli (
Fig. 2
A).
Mesosoma
. Mesosoma 1.3× as long as high. Mesoscutum setose, transversely striate (
Fig. 1
C). Notauli distinct, complete (
Fig. 1
C). Scutellar sulcus widely crenulated, divided by three carinae (
Figs 1
C, D). Precoxal suture well developed. Mesopleuron coarsely rugose in posterior half, microreticulate medially, rest unevenly rugose (
Fig. 2
D). Metapleuron rugose, faintly sculptured. Median area of metanotum with a complete medial longitudinal carina and a spine in lateral view (
Figs 1
D, 2E). Propodeum granulate with medial longitudinal carina, setose anteriorly, glabrous posteriorly (
Figs 1
C, D).
Wings
. Fore wing 2.8× as long as wide. Second submarginal cell short (
Fig. 1
F). Fore wing vein 1SR+M straight (
Fig. 1
F). Vein 2SR+M transverse, 0.38× as long as r. Vein C+SC+R and 1SR forming an angle of 60°. Vein 1SR distinctly curved. Vein cu-a slightly postfurcal (
Fig. 1
F). Length of vein SR1: 3-SR: r= 13: 4.4: 3.7. Length of vein m-cu: 2SR+M= 6: 2.4. Hind wing vein 2SC+R transverse. Length of hind wing vein 1r-m: SC+R1= 4.1: 12.5.
Legs
. Length of fore femur: tibia: tarsus= 7.6: 8: 8.5. Length of hind femur: tibia: basitarsus= 10: 13.1: 6. Claws with pointed basal lobe (
Fig. 3
D). Hind basitarsus 4.6× as long as wide.

Ranjith
, holotype
♀: A, first & second metasomal tergites in lateral view: B, second & third metasomal tergites in dorsal view: C, sixth metasomal tergite & ovipositor in lateral view: D, tarsal claw in lateral view.
Metasoma
. Metasoma 1.2× as long as head and mesosoma combined. First metasomal tergite rugose with complete dorso-lateral carinae, which unite shortly in front of posterior margin and with a forked structure posteromedially. Metasomal tergites 3–6 coarsely rugose (
Fig. 1
E). Second metasomal tergite without mid basal triangular area, coarsely rugose (
Figs 1
E, 3B). Second metasomal suture crenulated (
Fig. 3
B). Metasomal tergite 3–5 with transverse, crenulate, sub-posterior groove. Posterior margin of sixth metasomal tergite slightly emarginate medially and with a pair of lateral semicircular emarginations (
Fig. 2
F). Postero-lateral corner of sixth metasomal tergite rounded (
Fig. 3
C). Ovipositor sheath setose (
Figs 2
F & 3C). Ovipositor shorter than metasoma without pre apical dorsal nodus and ventral serrations (
Fig. 3
C).
Colour
. Body yellow except following dark brown to black: eyes, ocellar area, occiput medially and posteriorly, mesopleuron posteriorly, mesoscutum laterally, scutellar lunules, lateral sides of scutellum, propodeum, metasomal tergites 3–5 anteriorly, metasomal tergite 6 antero-laterally, fore and mid tarsal segments basally, hind femur except apically, hind tibia except basally, hind tarsus, pterostigma, wing veins, and ovipositor sheath; face posteriorly, mandibles apically, and mesoscutum mid anteriorly light brown, and ovipositor reddish brown.
