Porcellio Brevicaudatus
''Porcellio'' is a genus of woodlouse, woodlice in the family (biology), 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'' : ''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.

Porcellio Scaber
''Porcellio scaber'' (otherwise known as the common rough woodlouse or simply rough woodlouse), is a species of woodlouse native to Europe but with a cosmopolitan distribution. They are often found in large numbers in most regions, with many species (shrews, centipedes, toads, spiders and even some birds) preying on them. Taxonomy One subspecies, '' Porcellio scaber lusitanus'', is currently recognized. Two other subspecies were historically deemed valid but are no longer recognized. ''P. s. americanus'', described in 1932, was considered endemic the Americas. ''P. s. japonicus'' was described in 1928 and believed to be endemic to Japan. Both subspecies were synonymized with the nominate in 2020. Distribution ''Porcellio scaber'' is found across Central and Western Europe. In the United Kingdom, it is one of the "big five" species of woodlice. It has also colonised North America, South Africa and other regions including the remote sub-Antarctic Marion island, largely ...
