These tiny flies are only 5 to 6 mm in total length. I have several shots of collected specimens against a mm ruler. Several were collected for Dr. Riley Nelson at BYU and identified as this species.

shots as always. Yes the three Hadrokolos are all in Ok or Tx and the adjacent states. This species is known from AR as well (one specimen, I think Norm Lavers collected it). Tiny things.

The other two remain unphotographed in nature. And are tiny and elusive.
