Thank you. Might be
Fannia laevis (Stein). Most species near
canicularis have only one row of parafrontal setulae, according to Chillcott's revision.
Edit: Unless the row along the inside edge of the parafrontals doesn't count as one of the two; then it's probably
canicularis. The key to California species says
canicularis has prealar replaced by setulae like my fly, while
laevis has it strong.
