However, its proboscis strongly curves downward and doesn't fit with this fly. I think it's fair to say it belongs to Dasypogoninae (one can almost make out what appears to be a fore-tibial spine on the right tibia). Cell m3 being open helps narrow it down a bit. I'd say it is most similar to Tocantinia or Amorimius, but not a great match for either. A hard one to ID. Probably an undescribed species, and maybe genus for that matter.

She was ovipositing in the trail and I can usually sneak up close to ovipositing females. I followed this one around a bit trying to get close, but it tired of my presence and took off. I came back to the spot several times in the next days but no luck finding it on the trail or adjacent foliage. Plan to head back late Fall, fingers crossed.
