Found above the shoreline at Alameda, San Francisco. Trawling through BugGuide it "looks like"
Deopalpus hirsutus. Correct or something else?

Well, both have the “Peleteria”- bristle, so might be a good start.
I guess Jihn can tell more.

I think
Peleteria (Sphyrimyia). The subgenus name is used in the checklists published by the CNC, not in other literature. In general species of
Peleteria have 4 pairs of postsutural dorsocentrals while
Deopalpus have 3 pairs. There is also
Copecrypta with only a single strong parafacial bristle.

Thank you Theo and John!!
BugGuide lists only 2 species under
Peleteria (Sphyrimyia).
Peleteria haemorrhoa and
Peleteria anaxias! Of those I think this "should be"
Peleteria anaxias as
Peleteria haemorrhoa has a black triangle on the base of the fourth abdominal segment. My fly is missing that, as per the attached photo.
