This is a male Helina sp. Helina evecta fits nicely and it is usually the most common Helina around in the winter (here in Madrid, clearly). However, it is impossible to be sure with these shots (chaetotaxy needs to be checked) as there is at least another species extremely similar and climate conditions are very different in the mediterranean area compared to Madrid area.

I would leave it as a male Helina sp. Being optimistic, Helina cf. evecta ;)

Stéphane might be able to see more than I can though...
