Wasp or a fly? - Physoconops bulbirostris - Male

I found this critter yesterday. Not sure if it's a wasp or a fly.

Wasp or a fly? - Physoconops bulbirostris - male Wasp or a fly? - Physoconops bulbirostris - male

Moved
Moved from Subgenus Pachyconops.

Salient characters: vertex and frons entirely black; flagellomere and pedicel subequal; 1st posterior cell dark; mesopleuron without pollinose stripe; basal radial cell hyaline.

This can be seen to be a male, from the absence of a theca under the 4th & 5th sternites...which would be visible in the 1st image of the series if it were present.

Moved
Moved from Physoconops.

Moved
Moved from Physocephala.

This is Physoconops for sure. The 3rd antennal segment is way too long for Physocephala. And looking carefully at the 2nd image of the series, one can see that the position of cross-vein r-m is not well beyond the middle of the discal cell...again, indicating Physoconops (for details see here).

Moved
Moved from Conopinae.

Moved
Moved from Flies.

Conopidae
It is probably either Physoconops or Physocephala. More likely the first because I see no irregular thickening of the hind femurs but I would need a better look.

Moved
Moved from ID Request.

Look in Ceriini (Syrphidae).
