Agnaridae is a family of woodlice. They were formerly considered part of the Trachelipodidae, but were moved from that family to Porcellionidae in 1989, and then placed as a separate family in 2003. [2]
Isopoda is an order of crustaceans. Members of this group are called Isopods and include both terrestrial and aquatic species such as woodlice. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax.
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, butchy boys, and doodle bugs. 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.
Bathynomus affinis is a species of aquatic crustacean of the order Isopoda. It is known from the West Pacific (Philippines). There are minimal records of this isopod, all of them come from the early 1900s.
Echinodillo is a genus of woodlice in the family Armadillidae. It contains two species.
Styloniscus is a genus of woodlice in the family Styloniscidae. It contains the following species as of 2010:
Ceratoserolis is a genus of isopods in the family Serolidae from the Southern Ocean around Antarctica and some Sub-Antarctic Islands. They prefer to live on soft bottoms and range of least between 24 and 950 m (80–3,120 ft) in depth. They are superficially similar to the unrelated, extinct trilobites and reach up to about 8 cm (3.1 in) in length. They were once considered to be part of the genus Serolis and for a long time only Ceratoserolis trilobitoides was recognized. The validity of the other species has been disputed, but there are some morphological and genetic differences between them and C. trilobitoides, and there are indications that additional, currently unrecognized species of Ceratoserolis exist.
Nichollsia is a genus of isopod crustaceans from India. It comprises two species:
Anthuroidea is a superfamily of isopod crustaceans, formerly treated as a suborder, Anthuridea. The group is characterised by "an elongate cylindrical body form, without dorsal coxal plates, and with a uropodal exopod attached to the peduncle proximally and dorsally". There are more than 500 described species in 57 genera, arranged across six families:
A woodlouse is any crustacean belonging to the suborder Oniscidea within the order Isopoda. They get their name from often being found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects.
The Microcerberidea are a suborder of isopod crustaceans. They are less than 2 mm (0.079 in) long, and live interstitially. They may be found in the eastern Pacific Ocean, and around the coasts of South America, Africa, the Mediterranean Sea, and India.
Cancricepon is a genus of isopod crustaceans in the family Bopyridae including species formerly included in the deprecated Merocepon Richardson, 1910.
Chiridotea is a genus of isopod crustaceans in the family Chaetiliidae, containing the following species:
The Chaetiliidae are a family of isopod crustaceans in the suborder Valvifera, comprising these genera:
Glyptonotus antarcticus is a benthic marine isopod crustacean in the suborder Valvifera. This relatively large isopod is found in the Southern Ocean around Antarctica. It was first described by James Eights in 1852 and the type locality is the South Shetland Islands.
Dynoides elegans is a species of isopod crustacean in the genus Dynoides. It was originally described in 1923 by Pearl Lee Boone as "Cianella elegans" based on specimens from La Jolla and San Pedro, California. It was transferred to the genus Dynoides in 2000, when Boone's genus was sunk into synonymy with Dynoides.
Albunione yoda is a marine isopod assigned to the family Bopyridae, which is known to occur near Taiwan. It is an ectoparasite that resides in the gills of its host, the mole crab Albunea groeningi. A. yoda was named after a character of the Star Wars saga, Jedi Master Yoda, because with the slightly curved long lateral extensions of the head of the female, it looks like the head of Yoda with his long drooping ears.
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. Most of the armadillidae taxa are not monophyletic. 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. Some species, however, have secondarily lost their conglobation ability. For example, a species exist in which the males lack the inner face of the coxal plates and are therefore unable to conglobate. 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:
Deto is a genus of woodlice in the family Detonidae. Members of this genus can be found along the coasts in areas of New Zealand, Namibia, South Africa and Australia.
Dynoides indicus is a species of isopod in the family Sphaeromatidae. It can be found in the water near Sri Lanka.
