Hello,
Do you have an idea for this Tachinidae (male I think) ?
(Belgium, 12-07-2011).

Thanks

Hmm, not sure what it is but it looks very interesting :)

Thanks Chris, I think it's the first time that I see this one. Perhaps Theo will have an idea of what it could be ?

With two widely spaced IA can be some Leucostomatini, like Labigastera.

Thanks Erikas,

So the 2 widely spaced ia bristles behind the suture, the ocellar bristles raised and bent slightly backwards, and the large calyptra would be a good indication for Leucostomatini ?

In the key, there are 7 genus in Leucostomatini:

Cinochira is very different (the median vein runs in an even, weak curve to the wing edge without an angle forming the post-angular vein)
Clairvillia or Brullaea) have abdomen partially red
Leucostoma has petiole of R5 distinctly longer than r-m
Dionaea has 1 pair of strong acr before the suture (I see no ac before the suture on my pics)

So the 2 only possible genus should be Labigastera and Eulabidogaster, but this last one isn't given in Belgium on Fauna europaea and obs.be

If it is a male of Labigastera (no oe), as I see a complete row of marginal bristles on Tergites 2 et 3, it should be Labigastera forcipata (in the key, on T2 and T3 all the other species have only 2 dorsal marginal bristles and on each side 1+2 latero-marginals)

Do you agree ?

It was my first impression too, I just forgot to mention the complete name.

Thanks :)
I've read in the key that 2 hosts are given for Lapigastera forcipata : Enoplops scapha and Dicranocephalus agilis. I've seen Enoplops scapha at that place, and also a Dicranocephalus but the species medius not agilis.
