Sabiņanigo, NE Spain. Fresh mountain-climate, about 900 meters. River: with many trees and hedges in the sides. Contaminated, slow, with some lime and big stones, without water weeds, not deep. Mayfly: about 11-12 mm. wingspan, Three cerci, of very clear colour, very dark body, turbinate eyes.

Some helps can be given?

My guess would be a species in family Leptophlebiidae. The fact that the median filament is longer than the cerci should identify it rather easily for someone familiar with European mayflies. I recommend you ask Dr. Nikita J. Kluge of St. Petersburg University.

Edit: Now that I look at the photo again, I suspect the tails may actually be of equal length, and the angle of the photo makes it appear they are not. In any event, that impacts neither my guess as to family, nor my recommendation for consultation.
Best regards,
