Hi,
This Helina looks like H. reversio to me, but the fore tibia has 1 posterior seta. What is your opinion about this fly?

Is it impossible from these pictures?

I think it's
Helina quadrum.
Helina reversio-like with 1 pd on fore tibia is usually
H. quadrum.

Thank you so much for your opinion, Stephane! If I'm seeing correctly, the specimen has 3 anteroventrals and 2 anterodorsals on hind tibia. The 2 anterodorsals support the identification of H. quadrum. Is this enough to be sure, or is there always going to be some doubts?
