Ordo: Diptera

Genus: Metriocnemus
Name
Metriocnemus tristellus Edwards – Wikispecies link – Pensoft Profile
- Metriocnemus tristellus Edwards, 1929: 312
- Metriocnemus gracei Edwards, 1929: 312 sensu Wang 2000[1]: 637.
Material examined
CHINA: Zhejiang Province, Qingyuan City, Baishanzu County, 27°43'51"N, 100°7'33"E, 2 males, 18–22.iv.1994, light trap, H. Wu.
Remarks
The species has an AR = 1.2, very low inferior volsella, and weak anal point. Basal half of the wing membrane is bare, costa is strongly produced, and the distance C–M is rather less than M–Cu. The palp is unusually short, palpomeres 3 and 4 are less than three times as long as broad, palpomere 2 is rather longer. Wang (2000)[1] recorded Metriocnemus gracei Edwards, 1929 from China, which should be Metriocnemus (Metriocnemus) tristellus Edwards after we re-examined the specimen.
Distribution
The species is recorded from the Nearctic and Palaearctic regions (Ashe and O’Connor 2012[2]).The species has been collected in Oriental China for first time.
