. It looks as if neither of you specimens has ad setae. The top one probably would fall into the Mycetophila fungorum group, the bottom one in the Mycetophila ruficollis group. The former was revised by Chandler in 1993 (I think all genitalia jobs). Not sure about the latter, but European species of the ruficollis group are very similar and also require genital dissection for reliable ID.

You're right. It is searchable. I wonder why I got the idea it wasn't. I only went to the effort of generating a searchable version using OCR because searches weren't working. Oh, well.

Thanks for the additional identification suggestions.

BTW, I don't think an illustration of intersecting cylinders clarifies things because the limbs rotate and move back and forth. Put another way, I know ad bristles are between anterior bristles and dorsal bristles, but which ones are which? John Carr's original comment that fisherae and unipunctata both lack ad bristles on hind tibiae had me originally thinking that was an objection to those identifications based on those bristles being apparent in the photos. So I thought I was looking at ad bristles there, and I was trying to figure how that could be. That's why I posted later that I thought they did not have ad bristles. I guess I jumped to a conclusion reading something from John Carr that was not actually there.
