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 ("volvation") when disturbed.
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.
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.
Monolistra is a genus of isopod crustaceans in the family Sphaeromatidae. Its members are restricted to countries of the former Yugoslavia and neighbouring Italy. It contains the following subgenera and species, four of which are listed as vulnerable (VU) or endangered (EN) on the IUCN Red List:
Trichoniscidae are a family of isopods (woodlice), including the most abundant British woodlouse, Trichoniscus pusillus. Most species of woodlice that have returned to an aquatic or amphibian way of life belong to this family. Several species from the following genera live in water and on land: Titanethes, Cyphonetes, Alpioniscus, Scotoniscus, Bureschia, Brackenridgia, Mexiconiscus, Trichoniscoides, Cretoniscellus, Balearonethes and Cyphoniscellus.
Trichoniscus is a genus of woodlice. It contains over 100 species, including the common pygmy woodlouse, Trichoniscus pusillus:
Styloniscidae is a family of woodlice, including 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:
Porcellionides cilicius is a woodlouse that can be found on Cyprus and in Turkey. The species have one subspecies Porcellionides cilicius antiochensis that can be found only on Cyprus.
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:
Platyarthrus is a genus of woodlice in the family Platyarthridae. There are more than 30 described species in Platyarthrus.
Littorophiloscia is a genus of woodlice in the family Philosciidae. There are more than 20 described species in Littorophiloscia.
Cylisticus is a genus of woodlice in the family Cylisticidae. There are at least 70 described species in Cylisticus.
Pudeoniscidae is a family of malacostracans in the order Isopoda.
Mario Montesanto was an Italian association football manager and footballer who played as a midfielder. He represented the Italy national football team two times, the first being on 17 February 1935, the occasion of a friendly match against France in a 2–1 home win.
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.
Hawaiioscia is a genus of woodlouse known from the Hawaii, Rapa Nui, and Costa Rica. The genus was originally described from Hawaii on the presence of four troglobitic species on separate islands. A species within this genus was then described from Rapa Nui which lacked troglobtic traits, but only persists in cave-dwelling relict populations. Surprisingly, another species was then described from along the Pacific Coast of Costa Rica.
Hawaiioscia nicoyaensis is a species of woodlouse from Costa Rica. Its specific epithet is derived from the location of its type locality along the Gulf of Nicoya. It is the only known member of its genus to be found on a continent rather than a pacific island and the only one to be littoral halophilic. Furthermore, it is the only extant member of its genus not to be restricted to caves.
