Hi Valter, it´s a species of the albitarsis-group (C. albitarsis or C. ranunculi; just look at the tarsi: median tarsomeres of at least the fore tarsi pale ). I don´t know if you have C. ranunculi in Portugal. Genital dissection is needed.

The hairless spots on the abdomen, and the yellow tips of the femurs do not accord well with albitarsis. But it is hard to tell the coloration of tibia so it is hard to come up with suggestions.
