Asilidae; either Dasypogoninae or Stenopogoninae female. (Need to identify in hand).

Hi Jeff, really interesting finds! Any chance you could put these recent robber observations on iNaturalist?

The only "Stenopogoninae" that would be similar IMO is Grajahua (which was collected in Rio de Janeiro). 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.

Thanks Chris. I was so disappointed not to get better shots of this. 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.
