Remarks.

This species can be separated from other Metriocnemus species by the following combination of characters: acrostichals 4-5, uniserial; scutellum with 12 irregularly arranged setae; squama with 7 setae; anal point narrow and pointed with 14 setae at base, and gonocoxite with a small, dorsal, flap–like setose lobe. The specimens from Tibet have a lower antennal ratio (AR = 0.66-0.88) than the Indian specimens (AR = 1.03).

Distribution.

This species was described from India ( Chaudhuri et al. 1989). It has been collected in both Oriental and Palaearctic China.
