Identification
Main (visible) characteristics of the species:

- wide oval shape (wider and bigger than a usual P. scaber specimen)
- brownish color with typical lighter pattern (compare this with those under P. scaber on bugguide)
- 2 flagellae on each antenna (like every Porcellio)
- 2 pairs of bright white "lungs" on ventral side (like every Porcellio)
- well developed middle lobe on the head, but rounded rather than pointy
- and the most helpful: the shape of the telson is elongated with rounded tip and not pointy-triangle (e.g. that of P. scaber)
