Porcellio is a genus of woodlice in the family Porcellionidae. These crustaceans are found essentially worldwide. A well-known species is the common rough woodlouse, Porcellio scaber.

Most of the hundreds of Porcellio species were described by 1950, and many were known by the end of the 19th century already. But occasionally, new species have been found even in recent times.

Species

There are approximately 191 species in the genus Porcellio :{{cite journal |url=http://www.oniscidea-catalog.naturkundemuseum-bw.de/Cat_terr_isop.pdf |title=World catalog of terrestrial isopods (Isopoda: Oniscidea) — revised and updated version |author=Helmut Schmalfuss |year=2003 |journal=Stuttgarter Beiträge zur Naturkunde |series=Serie A |volume=654 |pages=341 pp}}

Porcellio cyclocephalus and P. notatus are fossil species from Baltic amber. They are placed in the present genus for lack of a better alternative, but whether this is correct is doubtful as the original descriptions are very brief and hardly diagnostic.
