Taken on 26th July in Valle de los Caidos - Madrid - SPAIN.

Tabanus, I think... Tabanidae by sure... conical form of body, big eyes comparing to the body. The first pair of legs seems "segmented"... wing venation very rich with many vein... cross-veins, I think...

Pity we can't see the eyes from front. See my comments at another post. Please make always a frontal picture of the head in living specimens of Tabanidae.
This is definitely no ordinary species. That's all I can say.
The wing venation is perfectly typical for Tabanidae.
As a matter of fact, the wing venation is remarkably uniform throughout the horsefly family. With only very small deviations from the general plan (see for more at Tabanus eggeri)

It helps if I say that where I found this tabanid, I found too Tabanus glaucopis? see here: http://www.flickr...207939418/

yes
My first thought was ... male Tabanus glaucopis.
However, I did not dare to publish this.
But now you mention glaucopis:
it could very well indeed be the male

Thanks
