I don't think that this is a Calliopum species. The head doesn't match in my opinion. Also, if you follow the keys to Calliopum from Remm Elberg 1979 (available in the downloads section at diptera.info), then you end up at tunisicum which is from Tunisia. My best guess is a Minettia species? I have no experience with Minettia. Maybe someone will see your post when they have time to review it... I hope that you have a Pleasant Day... John and Nini.

this one bother me because it has striped eyes like a Calliopum. If this is indeed a Calliopum species, then it should be Calliopum aeneum based upon the shape of the ovipositor. Using the keys from Shatalkin, it shouldn't have black femora and the thorax shouldn't be brown or bronze. I have not seen C. aeneum myself, so I'm thrown off by the colors here. I'm new to this genus. Atleast I'm trying to help you

In the Nearctic key Calliopum is distinguished by the combination of "anepimeron with one to several short, fine hairs above", dark color, and presutural dorsocentral bristle present. |

As far as I can tell this is indeed C. aeneum.

@tlegrand I had to look at my specimen of simillimum for the femora. The femora of simillimum are also dark but the apex is yellow-brown. I guess that the key is to indicate that the apex will also be dark for tunisicum. sorry about that. Also, my specimen has a bronze color too when viewed in strong lighting. Paul is the Lauxaniidae expert here so you have your answer
