Name
Metriocnemus brusti Sæther – Wikispecies link – Pensoft Profile
- Metriocnemus brusti Sæther, 1989: 407; Wang (2000[1]: 637).
Material examined
CHINA: Hebei Province, Pingquan County, Guangtou Mountain, 41°1'43"N, 118°43'1"E, 1 male, 29.vi.1995, light trap, H. Li. Guizhou Province, Daozhen County, Xiaosha River, 29°10'45"N, 107°32'59"E, 1 male, 25.v.2004, light trap, H. Tang.
Remarks
According to Sæther (1989)[2], the male can be separated from other members of Metriocnemus by having rounded crista dorsalis, anal point tapering to blunt apex, well sclerotized virga, comparatively sparsely haired wing with about 0–8 setae on Sc, 0–11 on M, 0–14 on PCu and 7–9 setae in cell m, and squama with 27–34 setae. The Chinese specimens have slightly more setae on wing membrane, with about 2–9 setae on Sc, 12–14 on M, 35–48 on PCu and 13–16 setae in cell m, but squama only with 15-17 setae. The species is similar to Metriocnemus (Metriocnemus) albilineatus (Meigen, 1818) and Metriocnemus (Metriocnemus) eurynotus, but has tapering anal point and rounded crista dorsalis. It has a well developed virga as in Metriocnemus (Metriocnemus) corticalis and differs from this species in minor details in the wing chaetotaxy and the hypopygium.
Distribution
The species is recorded from the Nearctic and Palaearctic regions (Ashe and O’Connor 2012[3]). It was collected in both Oriental and Palaearctic China.
