Hello,

this ~8mm tachinid is from last april from the mountains in the interior Sicily. Does anyone know what it is?

Thanks,
Michael

Wow - something very nice, I think :) Do you have any other angles? The petiole is confusing me because it doesn't look right for the rest of the fly - so it must be something I am unaware of :)

Eyes look too big to me, for any Estheria (etc) ... and the shape suggests something like Meigenia or Macquartia, but I don't think it is either of those :)

Hello,

I have two other pictures from slightly different perspectives. Here more from the side....

... an here a very very little bit more from above. But I am afraid I don't have a better view on the petiole.

Nice photos - but one for Theo, I think :)

I think we are dealing with a Rhinophoridae : the calypters are not adjacent to the lateral margin of scutellum. A Phyto maybe.

Yes, it is a Phyto.

Could have fooled me !

Thank you for the answers. According to the Fauna europaea there is only one Phyto species known from Sicily: Phyto adolescens. Could it be this species, or are there characteristics which suggest that it is something different?

I will look in to it.
It is surely NOT Ph. melanocephala.

Strange fly ... the standing-out calypters should have been a good pointer to rhinophoridae but the general shape is so uncharacteristic :S

I checked:

It is consistent with Phyto adolescens

CORRECTION

I meant to say it is consistent with Ph. discrepans, as far as I can tel. By no means a positive ID, though

(do not work when you are sick !)

Thank you for your effort Theo. I will labe the photos Phyto cf. discrepans. Do you think it is certain enough for the gallery in which this species still is absent?

So, I finally could reach out to a book, to look for an easy distinction between discrepans and adolescens.

Discrepans does not have marginal bristles on syntergite 1&2, adolescens does. And yours clearly does.
So, it is not discrepans.
I don't have adolescens in my collection, that is why I cannot compare it.

So please change into Ph. cf. adolescens.

Thank you very much again. To me Phyto adolescens now seems rather certain. In my photo collection I will skip the cf..
