Antenna with radicle, scape, pedicel and F1 – F3 dark black; F4 ventrally light brown, dorsally white; F5 – F6 and clava white. Mesosoma dark with greenish-blue reflections on mesoscutum; pronotum, axillae and scutellum with dark setae, mesoscutum with dark setae and also setae with dark base and silvery white apices; tegula in basal half white, apical half dark brown to black. Fore wing with infuscate band below venation, sub-basally and apically hyaline; hind wing hyaline; legs dark brown, except mid tarsi 1 – 4 segments and mid tibial spur white.

Comments
This species is similar to H. agarwali in having the ovipositor exserted, antennal scape less than 8× as long as wide, not constricted at middle, and hind tarsus dark brown, but differs from it in having ovipositor 2× as long as mid tibia; pedicel 2.4× as long as wide; F1 – F3 dark black; F4 dorsally white, ventrally light brown; F5 – F6 and clava white; (ovipositor 1.03× as long as mid tibia; pedicel 2.16× as long as wide; F1 dark brown, F2 dark brown but paler than F1; F3 – F6 and clava white in H. agarwali ).
Etymology
The species name is a Latin adjective in reference to the hilly terrain of the type locality.
