I found these 5mm flies on intertidal rocks in Northumberland (NE England) in the last week of July. I spent some time trying (and failing!) to get good pictures of the males flashing their white palpi, so I have quite a few shots of both males and females. Rather than post them all, I want to ask which areas it would be useful to see for identification. Is A. celtiber the most likely here?

Nobody replied to this, so I thought I'd add another image. Here's a female eating something interesting. What features are needed for identification?

Thanks Igor, that's pure gold. I'll look through all my photos and see if I can nail it down!

Well you know it ain't easy Grin But I did find one photo of a male fore-tarsus from the right angle to show the inflated areas (this key is for males only, right?). Is this enough to be confident that it is A. celtiber? The dcs seem rather variable, but most of the flies seemed to have enough at least on one side. I couldn't be sure of any of the other key characters from my photos.
