Oniscoidea is a superfamily of isopod crustaceans, which includes most of the land-living woodlice. It includes the "common woodlouse", Oniscus asellus , in the namesake family Oniscidae.
Fifteen families are recognised in the superfamily : [1]
Armadillidium is a genus of the small terrestrial crustacean known as the woodlouse. Armadillidium are also commonly known as pill woodlice, leg pebbles, pill bugs, roly-poly, or potato bugs, and are often confused with pill millipedes such as Glomeris marginata. They are characterised by their ability to roll into a ball when disturbed.
Porcellionidae is a terrestrial family of the order Isopoda.
Haplophthalmus is a genus of woodlice in family Trichoniscidae. It contains 47 described species, of which two are listed as vulnerable species on the IUCN Red List – Haplophthalmus abbreviatus and Haplophthalmus rhinoceros.
Styloniscus is a genus of woodlice in the family Styloniscidae. It contains the following species as of 2010:
Trichoniscidae are a family of isopods (woodlice), including the most abundant British woodlouse, Trichoniscus pusillus.
Philosciidae are a family of woodlice. They occur almost everywhere on earth, with most species found in (sub)tropical America, Africa and Oceania, and only a few in the Holarctic.
Trichoniscus is a genus of woodlice. It contains over 100 species, including the common pygmy woodlouse, Trichoniscus pusillus:
Porcellionides is a genus of woodlice in the family Porcellionidae. It includes the following species :
Platyarthridae is a family of woodlice, containing the following genera:
Trachelipodidae is a family of woodlice, containing the following genera:
Trachelipus is a genus of woodlice in the family Trachelipodidae, containing the following species:
Armadillidae is a family of woodlice, comprising around 80 genera and 700 species. It is the largest family of Oniscidea, and one of the most species-rich families of the entire Isopoda. Armadillids generally have a strongly convex body shape, with some rather shallowly convex. Like members of the woodlice family Armadillidiidae, armadillids are capable of enrolling into a sphere (conglobation), and are commonly known as pill bugs. Armadillids differ from the Armadillidiidae in that the antennae are fully enclosed within the sphere.
Scleropactidae is a family of woodlice, with a predominantly Gondwanan distribution. It contains the following genera:
Tylos is a genus of woodlice in the family Tylidae. There are at least 20 described species in Tylos. All the species in this family can roll up into a perfect ball and live on sandy beaches.
Alloniscus is the sole genus in the woodlice family Alloniscidae. There are more than 20 described species in Alloniscus.
Armadilloniscus is a genus of woodlice in the family Detonidae. There are more than 30 described species in Armadilloniscus.
Platyarthrus is a genus of woodlice in the family Platyarthridae. There are more than 30 described species in Platyarthrus.
Cylisticus is a genus of woodlice in the family Cylisticidae. There are at least 70 described species in Cylisticus.
Alpioniscus is a southern European genus of woodlice in the family Trichoniscidae. Alpioniscus consists of two subgenera: Alpioniscus s.s. and Illyrionethes.. A 2019 study used molecular and taxonomic analyses to verify the validity of the current taxonomy, resulting in the redescription of several species and the description of two new species.
