Metriocnemus (Metriocnemus) calvescens Saether

Metriocnemus calvescens Sæther, 1995: 45; Wang (2000: 637).

Material examined.

CHINA: Qinghai Province, Menyuan County, Haibei Station, 37°22'33"N, 101°37'20"E, 3 males, 12.vii.1989, light trap, M. Wei.

Remarks.

This species apparently forms the sister species of Metriocnemus ursinus (Holmgren, 1869). It can be separated from Metriocnemus (Metriocnemus) ursinus on its smaller size, by having only 27 setae in cell r4+5, only 26 setae on scutellum, and the presence of pseudospurs on fore metatarsus ( Sæther 1995). Compare to the holotype, the measurements of the two more males are very similar, except only 8-15 setae on scutellum.

Distribution.

The species was described by Sæther (1995) in Qinghai Province in Palaearctic China based on a single male specimen. Later two more male slides have been made which collected in the same location as the holotype.
