Dolichomitus khasianus Gupta & Tikar, 1976: 64.

Remarks.

This species is closely related to Dolichomitus flavicrus sp. n. Fore and mid coxae black, femora, tibiae and tarsi of mid and hind legs entirely concolorous yellow to reddish yellow, underside of metasoma including mesosternum and membranous area between sclerites entirely blackish in these species. However this species can be distinguished from the latter by the lack of a dark stripe on the posterior surface of the fore femur and by fine and dense transverse striations on the antero-median part of the first metasomal tergite (Fig. 1e ).

This species was described based on a single female from India. Sheng & Sun (2010) recorded D. khasianus from Yunnan in China.

Fore wing 25 mm, ovipositor sheath 95 mm.
