Remarks.

The Chinese specimens have a low number of setae on each of subcosta (0-9, 2) and M (4-20, 12), combined with a high AR (1.89-2.90, 2.24) and LR3 (0.44-0.50, 0.46), and a conspicuously long spur of the fore tibia (2.0-2.4 times as long as the apical width of tibia), these characters will distinguish the species from other members of Metriocnemus . Metriocnemus wittei Freeman, 1955 from Africa might be a synonym ( Sæther 1995).

Distribution.

The species is recorded from the Nearctic, Palaearctic and Oriental regions ( Ashe and O’Connor 2012). It has been collected in both Oriental and Palaearctic China.
