Name
Metriocnemus albolineatus (Meigen) – Wikispecies link – Pensoft Profile
- Chironomus albolineatus Meigen, 1818: 39

Material examined
CHINA: Sichuan Province, Ganzi City, Yajiang County, 29°53'48"N, 103°10'19"E, 1 male, 14.vi.1986, light trap, X. Wang.
Remarks
The male can be separated from other species of Metriocnemus by having a short virga (23–26 µm long), very weak inferior volsella, rounded to bluntly triangular crista dorsalis, tapering anal point with blunt apex, Sc with 10–31 setae, M with 15–32 setae, and cell m with 35–73 setae. This species is a member of the eurynotus group, but the male can be separated from other species of the group by having a shorter virga and a weaker inferior volsella. It has more setae on the wings than Metriocnemus (Metriocnemus) brusti and Metriocnemus (Metriocnemus) corticalis, but fewer than Metriocnemus (Metriocnemus) eurynotus.
Distribution
The species is recorded from the Nearctic, Palaearctic and Oriental regions (Ashe and O’Connor 2012[2]). In China it was collected from Sichuan Province in Oriental China for first time.
