If I am not mistaken this is A. leucogaster, a species, which was sometimes considered as a subspecies of trifasciata

OK many thanks Ruud. That would be a new species for the gallery and i can't find any photos of it on the internet or much distribution data beyond the type coming from Austria, a record in Sweden and a mention that it can be found in southern Europe. A. trifasciatus images seem to have a very similar wing pattern and white/grey marks near the tip of the abdomen, but my specimen has more white/grey marks on two more anterior abdominal segments, Is that the feature that suggests A. leucogaster to you, or something more subtle? I have no key/knowledge to work from, but it helps to know what separates similar species for future reference. For the record, the fly was at the same location as the Geron sp, between Vinjerac and Posedarje in Zadar province. And by the way, as you clearly know Bombyliidae well, did you see my recent query Toxophora fasciculata from Lesbos, http://www.diptera.info/forum/viewthread.php?thread_id=34814 I think it's pretty distinctive and looks very like an image that Jorge posted a while back, but I just don't know if anything similar exists and no-one has commented on it yet.
