Diagnosis
This species is distinguished from other species in the genus by the following characters: face tapering downwards in anterior view (Fig. 3A); mesopleuron coriaceous, matt, and impunctate (Fig. 3B); hind femur and basal tarsomere of hind leg slender (5.5 times as long as broad and 6.7 times as long as broad, respectively); transverse impression of first metasomal tergite not defined (Fig. 3E); face and scutellum black; metasoma red centrally (Fig. 3E).

Description
Female
Fore wing 7 mm long. Antenna slender, about as long as fore wing, with 28 flagellomeres. Ratio of length of 1 st plus 2 nd flagellomeres to eye height 1.2. Scape 1.25 times as long as broad. Head weakly narrowed behind eyes, matt, without punctures and shagreened (Fig. 3D). Lateral ocellus separated from eye margin by 1.8 times their widest diameter. Face transverse and tapering downwards in anterior view, 2 times as wide as high, shagreened and without punctures (Fig. 3A). Clypeus 0.35 times as high as wide, distinctly separated from face by a deep groove, projecting medially, shining and impunctate, its apical margin thin and impressed laterally. Clypeal fovea not enlarged. Malar space 0.7 times basal mandible width. Occipital carina complete. Mandible teeth almost equal but lower one is slightly shorter than upper one.
Mesoscutum weakly shining, finely granulate, with dense and irregular punctation. Notaulus distinct. Mesopleuron shining, finely granulate and weakly striated in upper part (Fig. 3B). Metapleuron rugose and weakly shining. Propodeum strongly rugose (Fig. 3C). Area superomedia fused with area basalis, their combined area 2.6 times as long as broad. Costula absent. Area apicalis trapezoidal, 0.6 times as long as broad, and equal to 0.5 of propodeum, often with longitudinal carina and sometimes with striation. Spiracles weakly oval, 1.2 times as long as broad. Hind femur 5.5 times as long as broad. Hind tibia 7.8 times as long as apically broad. First tarsomere of hind leg 6.7 times as long as broad and 2.1 times as long as second tarsomere. Claws not pectinate. Fore wing with pterostigma elongate, around 3.6 times as long as broad and intercepted by Rs before its middle. 2m-cu straight, with a single bulla. Cu-a reclival, postfurcal. Hind wing with 1/Cu & cu-a intercepted by 2/Cu in lower 0.5.
Colouration: body black; clypeus, antennal flagellum, femora, tibiae (except apical part of hind tibia), and second and third metasomal tergites reddish (Fig 3).
Male
Morphologically similar to female. Parameres projecting weakly beyond aedeagus.
Host records
