6. Parancistrocerus incorruptus Giordani Soika, 1972

Diagnosis: Female: Superior carina of propodeum little developed and irregular, hence no true dorsal surface of propodeum clearly separated from posterior; T2 swollen on sides, about as wide as long, having strong preapical groove, strongly punctured, followed by long translucent area, strongly reflexed and prolonged in middle; head, in frontal view, subcircular, about as wide as high; clypeus about as wide as long, weakly emarginate at apex, apical teeth short but sharp; eyes much closer to each other at clypeus than that on vertex; posterior ocelli closer to each other than to eyes; metanotum with very short horizontal dorsal face and much longer posterior face; tegulae wide, slightly longer than wide, with short, pointed posterior lobe; dorsal face of T1 about as long as wide at base; clypeus shiny, with more or less superficial punctures, of different thickness and average density, interspaces on average much more than diameter of punctures; T1 and T2 with punctures deep, round and little oblique, larger and more spaced than in mesoscutum; S2 with punctures even bigger, but much thinner than corresponding tergite.

There are three subspecies, namely, P. incorruptus demens Giordani Soika , P. incorruptus incorruptus Giordani Soika and P. incorruptus kalimpongensis Giordani Soika , all present in the Indian subcontinent.
