So what would I have to see/photograph to get to species level?? Or is this a dissection-only genus?

Generally, it is easier with males of this genus. Then, you need a good photo of the front leg, really...males have distinctive hairs on the femur and swollen tarsal segment...and of the pattern of spots on the abdomen. It is not a dissection genus, but they do need a close look and are difficult from photos. As many angles and as much detail as possible, I suppose.
With a female, like this one, small grey-spotted flies are often P. albimanus, but there are other possibilities.

Thanks Ian - will look at being a little more critical with my photos in future...!
