Paxodillidium
''Paxodillidium schawalleri'' is a European species of woodlouse endemic to Greece. It is currently the only known member of the genus ''Paxodillidium''. Its true affinities within the family Armadillidiidae are not known. Taxonomy ''Paxodillidium schawalleri'' was described as the only member of the genus ''Paxodillidium'' by Helmut Schmalfuss, in 1985, based on specimens collected from the island of Paxos. Its true affinities within the family Armadillidiidae are yet unknown, but two hypotheses have been made: *The first one states that ''Paxodillidium'' is related to '' Cyphodillidium'' and '' Echinarmadillidium'', two genera that also show a distinct ornamentation on the tergites. From these two, ''Paxodillidium'' is believed to be more closely related to ''Cyphodillidium'', with which it shares the development of a frontal edge on the head. On the other hand, it differs from it by the presence of more flattened epimera and individualized tubercles on the tergites. *The s ...

Armadillidiidae
Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of some other woodlice families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals. This ability gives woodlice in this family their common names of pill bugs or roly polies. Other common names include slaters, potato bugs, doodle bugs and cheeselogs. Most species are native to the Mediterranean Basin, while a few species have wider European distributions. The best-known species, ''Armadillidium vulgare'', was introduced to New England in the early 19th century and has become widespread throughout North America. Ecology and behavior Pill bugs in the family Armadillidiidae are able to form their bodies into a ball shape, in a process known as '' conglobation''. This behaviour is shared with pill millipedes (which are often confused with pill bugs), armadillos, and cuckoo wasps. I ...
