Careful there! There is a small marking at the tip of the wing but in the genus Sepsis and the closely related ones it is at the apex of vein R2+3. Here it is at the apex of R4+5! Moreover, virtually all of the species in that group of genera are (largely) blackish, and this one is brown. The manual of Nearctic Diptera mentions one pale brown species (Meropliosepsis sexsetosa) but that is only found in Central and South America... Other aberrant features are the somewhat protruding head and the rather narrow wings. My suspicion: Myrmecothea myrmicoides of the Ulidiidae. Paul - - - - Paul Beuk on https://diptera.info |

Hi Paul, Sorry to take so long to get back about this one. I sent the image back to the person who knows Ulidiids well and who first suggested Sepsidae. He said: "I stand corrected. It isn't a sepsid. The ovipositor is of the tephritoid type. But it also isn't Myrmecothea myrmicoides. I think it is Sepsisoma flavescens Johnson (Richardiidae) female." He then said it would help if he sould see the hind femoral spines and wing venation. A blowup of the leg was too fuzzy, but that of the wing venation fits the Sepsisoma. This has been a controversial fly. |
