Seems freshly emerged from riverside, ... not collected. (Iberia: Girona province; Beuda: Riera de Rajolins: 380 masl; 2016 August the 2nd)

As I can't get at the moment the Iberian Portillo keys I have followed Kroatian keys (Krcmar, et al, 2011). Unfortunately I didn't measure it. So I think we have to look at the hairs of the vertex (pale and dark in exclusus; black in glaucopis) and the subcallus (only apically polished in exclusus and completely polished in glaucopis)... but i dont' trust too much theses features....
Tabanus glaucopis is common in my area.

Can anybody help?

Life is not so simple.
You have several other species.

For starters, it is not exclusus.

Could you please upload the fullsize of the upper left photo of the second picture ?

And for future cases: please make the head shots strictly frontal and strictly lateral.
these shots with oblique anglea are very hard to interpret.

Thanks

Theo

You can see the very stout palpus and the antenna is black. This does not fit any species in the glaucopis group, but rather suggests cordiger group.
If ther would be one eyeband, the only option with a big head is leleani, which is definitely not Spanish.

So I am lost.

Did you happen to note the number of eyebands ?

I'm sorry Theo. Pictures don't help, and some parts were taken in shadow conditions. In the picture with green background the antenna don't look completely black.
The subcallus looks polished in the upper part (i would suspect is more unpolished as it was freshly emerged). I thought this could help.
I think the eyes in the lower part have at least three stripes.

Next time I will collect it.

It will remain a mystery.
there is only one species in the glaucopis group with stout palpi, and that is T. fraseri from Turkey......

We have had this discussion before (with a female Tabanus):
http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=54882
When you say "stout" do you mean thick? Or short?
There are pictures on the web (some of the from this site) of "Tabanus glaucopis male" that look similar.
But anyway all my specimens are smaller than they should.
May be I can send them to you?
All the best anyway,
Rafael

I didn't realize you collected this male !
If I have it on my desk, the mystery is likely soon solved.
So I'd like to study it.
If you need my postl address, send me a PM.

Thanks

I looked at it again.
This is not glaucopis and I am pretty sure it is the male of leleani.
This would, however, be the first record for Spain.
Leleani is generally more eastern, but it has been recorded from Morocco.

So, maybe this year you can find this species again and collected !
Would be a first for Spain.

By the way, the material you sent are typical glaucopis, as already noted by yourself. I agree.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
