Hello! :D

Orange flies have to wait, this is too funny!

13th October, on a leaf overhanging water near the Ivy! Approx. 5.5mm. My garden near Lincoln UK.

Syntormon?

Syntormon was the genus I had thought too Paul, there's not one in the gallery which matches mine though. S. pallipes female comes close but it doesn't appear to have the muppet face. ;) Besides that there is
bicolorellum and pumilus

Here's a list of the species we have.. 16 species!

I have looked at a key for Syntormon an come up with Syntormon denticulatum.

http://www.fortun...tormon.htm

3.– Females; face broad; clypeus convex ... 15

20. – Fore coxa with white hairs, sometimes with 1-2 black setae at apex; frons brownish pollinose; fore tibia with anterodorsal serration; mid coxa without strong setae ... denticulatus(Zetterstedt)

23. Frons mat, bronze-green ... denticulatus (Zetterstedt)

Have I done this correctly?

Sir,

Syntormon denticulatum would be my best guess too, on the basis of the bare face and the dark legs. Perhaps you could only check if S. zelleri shows very different features, although this species is much rarer than S. denticulatum and occurs in more oligotrophic habitats and at primarily at high altitudes.

Cheers,
Marc

Thank you Marc.

I found a photo of only a male S. zelleri on the same site, although I have some more keys in a pdf which I will take a look at as the key above doesn't look to have S. zelleri included.

Roger, I know what you would be calling me! :P

Marc, I have checked the key on the pdf. All seems to fit Syntormon denticulatum.

15. Mid tibia with 3 anterodorsal, 1-2 posterodorsal and 1 ventral setae; antennal
stylus 1.5 times longer than postpedicel (along dorsal margin); m-cu
shorter than distal part of CuA1; lower calyper with white cilia; 2.5-4.0 .......
..............................................................................denticulatus (Zetterstedt)


http://www.dipter...Europe.pdf

Again, S. zelleri is not listed.

Can I say for certain this is Syntormon denticulatum.? It would be a good addition to the gallery!

Mid tibia..

I am now confident this is Syntormon denticulatum

Syntormon denticulatus (Zetterstedt, 1843) (-us; F -um) [Rhaphium] (Loew, 1857: Progr.Realsch.Meseritz 1857: 34-35)

Syntormon bicolorellus (Zetterstedt, 1843)

Syntormon pumilus (Meigen, 1824)

etc.

The author of the genus (Loew) used Syntormon denticulatUS (Zetterstedt, 1843) for Rhaphium denticulatUM Zetterstedt, 1843.
Therefore, masculine gender must be applied to all Syntormon species.

Thank you Igor, I'll wait to see if Paul sees this. If not I will contact him to make the change from denticulatum to denticulatus.
