Thread subject: :: Tachinid for ID, SE Spain --> Graphogaster vestita

Posted by Piluca_Alvarez on 13-11-2011 22:28

Pictures taken by my friend Francisco Rodriguez in Alicante, SE Spain.

Can this be Phasia? The vein r4+5 fits pretty well with most species but I cannot find anything that matches this fly. Probably I am missing something. Help, please!

Thanks in advance!

Another view.

It has significant bristles on the abdomen so cannot be Phasia ... but it should be Phasinae. Perhaps Rondania or something like that? Whatever it is, it looks very interesting :)

Well spotted, Chris!! I should have notticed that. Loads of bristles in the abdomen, so it is something else.

Will continue my research and let's see if Theo can put some light in this!

Thanks a lot for your help, Chris! :)

Looks very interesting, pretty dark for a Rondania but I don't have all species in the frontal lobe of my brain.

I have to check this one

I think I'll change horse mid-stream ... how about Graphogaster? :)

Posted by Zeegers on 15-11-2011 10:48

That is it, Chris, thank you.

It is the male of Graphogaster vestita, you can see the marginals on T4 are lacking (though discals present), a very peculiar feature.

This species is relatively common in the Mediterrean, so that figures

Right !

Note that this species has a strong sexual dimorphism.

Very nice - I've never seen that one ... the only Graphogaster we get here is brunescens, but that's very rare and I've only ever seen it from Jari's samples from Finland. Do you find Graphogaster generally rare in northern/central Europe Theo?

Posted by Piluca_Alvarez on 15-11-2011 15:01

Thanks sooooo much, Chris and Theo!!! This is really nice!! I never thought we might get even the species! Superb!

And Paul, I will ask Francisco for permission but I am pretty sure he is going to say 'Yes, of course!' He is way too grateful to you guys for all the help and patience IDing our Spanish stuff. And it isn't an easy task, just from pictures taken in the wild!

I will do my best to get you the Peleteria ruficornisfor the gallery too ;)

Well, there are more or less three branches of Graphogaster

Several species in the high mountains, all very rare

this vestita, as said pretty common in Mediterrean

and finally brunnescens, the only one in lowland temperate Europe. In my experience mostly in coniferous forests, so Finland should be ideal.
