according to German fauna, this should be S. major but you may have others in Portugal.

the fore tibia is not apically broadened so we can eliminate S. longipennis. The head is not elongated and the face stripes are black, so we can eliminate S. minutus. I believe that S. fuscovittatus has a stripe on the foretibia and not two thin stripes. None-the-less, I think it should be S. major. genitalia of the male can be used for a positive id. Otherwise, you will need the opinion of an expert for certainty.

considering that i don't have a specimen, based upon these photos i call it S. major.
