I have bee working through my Sciomyzids and I am finding the Pherbellia hard going, characters like 'depth of cheek greater than half of width of eye' are a bit frustrating when you only have your eye to guess with and they look about half, not greater or lesser.

So I am wondering if anybody would be willing to take a look at a few specimens for me, in alcohol or pinned, to give a baseline, I think I have only 3 or 4 species.

Thanks to anybody who volunteers ;).

Thanks Nikita,
I will send you a few specimens to check when i have finished playing with them. I have a few more to pin first.

I have one species that keys out as P. brunnipes, but I am a little worried that Rozkosy's discription does not mention the obvious, silvered orbito-antennal spots (look brown in wet specimens) which he does mention for other species when present.

Also I am a little concerned by the second half of couplet 27

"Row of small hairs along lower frontal eye-margin present, with at least several hairs distinct between anterior orbital seta and base of antennae."

How can the hairs be on the lower margin of the eye and between the OS setae and the antennal base at the same time??
