hairy anthomyiid - Eutrichota fuscipes - female

hairy anthomyiid - Eutrichota fuscipes - Female
North Bethesda, Montgomery County, Maryland, USA
January 31, 2017
Size: length ~10mm to wingtips
This one keys out to Eutrichota in the MND anthomyiid key (1) (as Eremomyioides in the key = E. cylindrica superspecies). Character states from the key seen in this fly by couplet: A1 traceable to wing margin; C without widely spaced coarse setae on lower surface distal to subcostal break, ventral surface of the scutellum appears to have hairs; katepisternal bristles not arranged in an equilateral triangle, wing unlike Chelisia; ventral hairs on scutellum again; middle of proepisternum with hairs; anepimeron, meron, katepimeron, and prosternum simultaneously with hairs (with no one photo showing all 4 sclerites). Consistent with Eutrichota, there are bristles above the vibrissae. The swollen fore tarsi are also consistent with the E. cylindrica superspecies/Eremomyioides.

The key in Huckett’s Eremomyioides revision (2) appears to lead to E. fuscipes: 5th abdominal tergum not rounded or swollen; mid & hind femora largely blackish; only 2 anterodorsal and 2 posterodorsal bristles on the largely blackish hind tibia; inner margin of 2nd antennal segment extending obliquely across base of 3rd segment w/ angular projection on lower half, costal setulae scarcely longer than costal width.

After all that, it will probably turn out to be something else. I’d appreciate confirmation/correction of the ID. TIA
