Taken on 9th August 2009, on my neighbour's marqee near Lincoln UK. One pic only but I have cropped off the head so posting two.

Scathopahgidae. Nanna perhaps?

---

If it is Nanna, we have 7 species listed. N. armillata, brevifrons, fasciata, multisetosa, tibiella, flavipes and inermis. The last two are in the Gallery and I don't think look like mine although the legs on N. flavipes look to match.

I'll change the title and hope someone can give it a name.;)

---

Try to check the key. Nanna has 2 setae on scutellum, and this fly has 4.

---

It was just a suggestion. I did not have a key at hand, so...

---

I think it is Trichopalpus (=Chaetosa) punctipes, but I can't be sure without a lateral view.

---

Thank you Stephane, if you are sure it is a Chaetosa sp. then we only the ones species listed for the UK, C. punctipes.

I checked Trichopalpus, we only have one species of that which is Trichopalpus fraternus

Both have a synonym or previous genus of Cordylura.

This might all be outdated, so where does that leave us?;)

---

Chaetosa punctipes is a synonym of Trichopalpus punctipes, and I am not sure of the genus.

---

I have checked on ITIS, as well as Biolib, there appears to be only one species of Chaetosa, which is C. punctipes.

GBIF shows it in my area,

http://data.gbif....s/16084659

The NBN shows it either side of me but it's never up to date or is under-recorded.

http://data.nbn.o...0000030398

The synonym there is also Cordylura punctipes

The only reference I found for Trichopalpus punctipes was on a Norwegian document, neither ITIS or Species 2000 recognises it.

BUT there is a fly named Trichopalpus punctipes in the Gallery, and I have found the source of the name on a google, from an old thread here! It is from Gorodkov's key in Insecta of European part of USSR, 1970, vol.5, part2.

Does the current taxonomic information make this name incorrect?
