P. spinicornis
Hi! It's a nice picture!
The species name is Porcellio spinicornis.
At first it looks similar to Oniscus asellus, but it differs in important details:
- the antennae have TWO flagellae (and not three)
- head has well developed middle lobe, and lobes on the sides
- head is always dark
- TWO pairs of white lungs can be seen on the ventral side of abdomen
In Europe the species is widespread, its northern limit is southern Scandinavia, but not as frequent as Porcellio scaber.
