Psila sp. ? Am I right? thank you.

Hmm, it looks like no Psilid I have seen. But then again, I have hardly seen them all :) Definitely not Psila though. Oxypsila sp. ?

it is nice to see that this fly is putting doubts. :)

I have a male of this one, I think. I will upload the photos very soon.

In our Dutch key Oxypsila is keyed out as having no dorsocentral setae, but this one has two prescutellar dc. Following the key I would have to say it is Chamaepsila but that does not ring right when looking at the Chamaespsila we have here.

Very nice fly indeed. I'm very curious what it will turn out to be!

let me know if you want a detailed shot of terminalia... and others. I have almost photos from all angles. But I just can upload the photos on Wednesday.

this case is getting more and more interesting.
Bernhard Merz told to me : "According to my knowledge and our reference collection it is a species close to "Psila" gracilis Loew. However, there are some differences, in particular in chaetotaxy of the head and in the arrangement of the black stripes on the mesonotum. (...) without checking some crucial characters (fine setulae on thorax, exact distribution of setae, wing shape and venation, more precise study of head shape, and of course of the female terminalia) it is not possible to establish the name, even the genus is not fully clear."

Be tunned. Hopefully I will upload photos more later. :)
