Taken in December in the Kanuku mountains of Guyana. Lowland Amazon rainforest.
Hopefully someone can help with an ID for this guy.
Thanks,
Paul

Change heading to Dolichopodidae to attract Igor or Stefan or possibly Marc. :)

Dear Pbertner,
Well, you attracted me anyway (with some patience) ...
Very hard to tell what this is because there is not lateral view. Moreover, it looks like a female specimen. I do not fully agree with Stefan: he is right in that it is a dolichopodine, but to me it's not necessarily Paraclius. If the face would outreach the lower eye edge, it might as well be a Tachytrechus (a paraphyletic assemblage to me), or even a Pelastoneurus (I don't get a clear view of the arista and can't see if it's plumose or not). Paraclius remains an option too.
Cheers,
Marc

Hello Marc!
Tachytrechus species usually have an ovate third antennal segment and 2 or more preapical setae on the hind femur;
Pleastoneurus species usually have a plumose arista and a slender hind femur. This species has an acute third antennal segment, only one preapical seta on the hind femur (so far I can see), the arista is not plumose, the hind femur is thick – all these characters lead to the genus
Paraclius.
Best wishes,
Stefan
