Material examined

Holotype: Female ( ICAR / NBAIR / P1147 ), INDIA: Karnataka: Chikkaballapur, Nandi Hills , 13.3702°N, 77.6834°E, 1448 m, SN, 22.XII.2009, KV. GoogleMaps

Etymology

This species is named ‘ parallelogaster ’ referring to the lateral margins of tergites 3–4, which are parallel to each other. The name is treated as an adjective.

Diagnosis

The parallel lateral margins of tergites T3 and T4 distinguish this from all other species.
