Hello together,

this morning in my garden (Hamburg, West Germany, MTB 2424) I found this about 20mm Assilidae. The long wings where all the time open, what I've never seen at this flies. Is a indentification possible?

Friendly greetings

Kirsten

Hi Valerio,

thank you, I'm not against ;-) . Up till now I've seen one Machimus in 2005 an made realy bad pics. Is there a chance for a nearer identification today?

Initially was thinking about Philonicus albiceps, but it doesn't convince

Eutolmus rufibarbis, I would say. The ovipostor (it is a female) is laterally flattened, and the dorsocentral bristles on the thoracic dorsum are not present at the front.

Theorically ovipositor is also somehow narrowed even in Machimus complex. Of course here is greatly compressed.

But is the overall shape of this female that made me converted to your idea about Dysmachus complex (which for some authors includes Eutolmus sp.). The kind of constriction in the ventral surface of the ovipositor really reinforces E. rufirbarbis ID (+ scarcity of acr & dc pre-sut.).
