Eluma is a genus of woodlice in the family Armadillidiidae. The members of this genus are native to the Iberian Peninsula, Morocco, the Atlantic islands of the Azores, Canaries and Madeira, and from the west of France to the British Isles. [1] [2]
Eluma contains the following four species: [3]
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.
Echinodillo is a genus of woodlice in the family Armadillidae. It contains two species.
Metatrichoniscoides is a genus of isopod crustacean in family Trichoniscidae.
Moserius is a genus of crustacean in family Trichoniscidae, with two described species:
Woodlice are terrestrial isopods in the suborder Oniscidea. Their name is derived from being often found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects.
Trichoniscus pusillus, sometimes called the common pygmy woodlouse, is one of the five most common species of woodlice in the British Isles. It is acknowledged to be the most abundant terrestrial isopod in Britain. It is found commonly across Europe north of the Alps, and has been introduced to Madeira, the Azores and North America.
Ligia is a genus of isopods, commonly known as rock lice or sea slaters. Most Ligia species live in tidal zone cliffs and rocky beaches, but there are several fully terrestrial species which occur in high-humidity environments.
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.
Iridovirus armadillidium1, known formerly as Invertebrate iridescent virus 31 (IIV-31) and informally as isopod iridovirus, is a species of invertebrate iridescent virus in the genus Iridovirus. Oniscidea serve as hosts. Infection is associated with decreased responsiveness in the host, increased mortality and the emergence of an iridescent blue or bluish-purple colour due to the reflection of light off a paracrystalline arrangement of virions within the tissues.
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.
Lusitanipus is a genus of millipedes in the family Dorypetalidae. The genus is endemic to the Iberian peninsula; L. alternans is endemic to Portugal and L. xanin is only known from Spain. It was believed to be a monotypic genus until the 2020 discovery of L. xanin.
Armadillidium sfenthourakisi is a European species of woodlouse endemic to Greece.
Armadillidium maniatum is a European species of woodlouse endemic to Greece.
Paxodillidium is a genus of woodlice endemic to Greece. It is monotypic, being represented by the single species Paxodillidium schawalleri. Its true affinities within the family Armadillidiidae are not known.
Armadillidium phalacronum is a European species of woodlouse endemic to Greece. It is a relatively small-sized species that probably belongs to the so-called "Armadillidium insulanum complex".
Porcellio hoffmannseggii, commonly called the titan isopod, is a species of woodlouse of the genus Porcellio described in 1833. This very large species is native to the southern Iberian Peninsula, Morocco and the Balearic Islands.
Porcellio scaber lusitanus is a subspecies of Porcellio scaber endemic to Spain and Portugal. Described in 1907 as Porcellio lusitanus the species was later lowered to a subspecies level despite being referred to as a form. It is highly likely that Porcellio scaber lusitanus are normal P. scaber with Allometric Growth.
Trichorhina anophthalma is a species of woodlouse distributed throughout southern Spain and Portugal.
