I have no clue to which family this fly (2.2 mm) belongs. Very strange venation.
I found this specimen on a wall in Minas de Riotinto, Huelva.

Any idea?

Thanks! TumbsUp

Thanks, Tony! I have seen many Ceratopogonidae, but never like this one. TumbsUp

The short, oblong radial cells are a good indicator for Ceratopogonidae.

Ceratopogonini, likely Ceratopogon.

Wing veins also match Culicoides which has more hairs on the wing and shorter claws.

I found some information about this genus.

Iberfauna only names one species for Spain, Ceratopogon niveipennis.
http://iberfauna.mncn.csic.es/showficha.aspx?rank=T&idtax=63066

As I have no idea whether this is correct I read "Beitrag zur Kenntniss der Gattung Ceratopogon Meigen" by J. Winnertz.
The description of its syn, C. candidatus and drawing of the wing fit my specimen.

Is it possible to identify these species by photo?


¡Saludos!
André

Four species are known from western Europe. Quoting Art Borkent: "They are generally early spring, alpine or arctic species and the genus is strictly Holarctic. Many females are difficult to identify even after slide mounting but the males, with very large genitalia, have good characters."

Andre, if you can check on original image if you can see an internal tooth on the tarsal claws then, please, do so. From this image it seems to be absent (although that may be because of orientation of the visible claws), but the tooth should be present in niveipennis.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol
