Looks very interesting (thickened arista, wing venation, setae on face), but does not ring a bell (??Elodia??)

Thanks a bunch for your input, Theo! :) But if it doesn't ring a bell for you, that is really bad news ;):(

Marian took some pictures of it too. I will ask her to post them in this thread just in case her shots add some information. She might have got better detail.

Please, keep an eye on this thread ;););)

Hi, folks!

This is the only decent picture I got of the little character, I managed to blur all my pics!!!:@

Hope it adds some light to the "mystery". ;)

Cheers!

I happen to have 1 Policheta unicolor (a rare species here) :D and it does look very good ... it has:
- the facial ridge bristles
- hairy eyes
- short diverging apical scutellars
- lots of median dorsals on the tergites
- lateroclinate parafrontals
- 3 post-dc and post-acr
- excavation of T1+2 not reaching the margin

My only slight doubt is the colour - mine is very black but this seems to have a blue cast to it.

... so it is Policheta unicolor or something very closely related to it ;)

Thanks a lot for the ID and the efforts you are making, Chris! And Policheta unicolor is listed as an Iberian species too! :D That is good news!!

About the colour, when we saw the fly we described it as 'the blackish Tachinid' not bluish. I think due to light, it looks more bluish in the pictures than it really is. It was more greyish than bluish, but definitely black.

I guess that if it is confirmed, Paul would like to have those pictures in the gallery ;)

I don't want to spoil the meal, but the praealar seta is strong, so it seems....

I think I see a weak pre-alar in front of a strong supra-alar

I also see a strong pre-alar... so what can this be? Really the mystery of the month.

Jorge has told me that H. P. Tschorsnig has confirmed it is Policheta unicolor. He said:

'The lateroclinate outer orbital bristles and the erect mouth margin are typical for this species.'

Thanks a lot to anyone that has taken part of the discussion about this interesting and unexpected Tachinid :)

And of course, the pictures will be submit to the gallery soon ;)
