Hello

I would like to request your help to identify the fly in the picture. It was taken today close to a small pond in a summer-dried brook in a cork-oak and Aleppo pine forest in NE Catalonia (Spain).

It seems to me a possible Dolichopodidae but the long antenae are unexpected to me.

Thanks a lot in advance

Miquel

Now Sybistroma (again).
Multiple male colour and morphological ornaments (male secondary sexual characters or MSSC) are commonly found on antennae, mouthparts, legs, wings and abdomen in many Dolichopodidae species in addition to large genital capsule (hypopygium). This decoration developed more in tropical species marks out long-legged flies from all other Diptera (Sivinski, 1997).

Sybistroma dufouri Macquart, 1838: Ann.Soc.ent.France 7: 427 ** Type locality: France: Saint-Sever. Palaearctic: Balearic Is., France, Spain, Greece, Italy, Macedonia, ?Yugoslavia, Morocco, Algeria *
