Trichorhina argentina is a species of woodlouse found in southern Brazil and central eastern Argentina. [1] It can be found living synantropically under stones or leaves. [2]
The males can get up to 2.98 mm (0.117 in) long and 0.25 mm (0.010 in) wide. The larger females are up to 4 mm (0.16 in) long and 1.75 mm (0.07 in) wide. Their coloration is light brown, with white spots, while the uropods are generally colorless. The head, if in normal position, is partially surrounded by pereonite one. The eyes are black with five to six ommatids. Their antennules are fitted with seven to eight aesthetascs. The pleon narrows gradually after the posterior end of the pereon. The telson is triangular with an obtuse peak. [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.
Cymothoa exigua, or the tongue-eating louse, is a parasitic isopod of the family Cymothoidae. It enters fish through the gills. The female attaches to the tongue, while the male attaches to the gill arches beneath and behind the female. Females are 8–29 mm (0.3–1.1 in) long and 4–14 mm (0.16–0.55 in) wide. Males are about 7.5–15 mm (0.3–0.6 in) long and 3–7 mm (0.12–0.28 in) wide. The parasite severs the blood vessels in the fish's tongue, causing the tongue to fall off. It then attaches itself to the remaining stub of tongue and the parasite itself effectively serves as the fish's new "tongue".
Oniscus asellus, the common woodlouse, or common shiny woodlouse is one of the largest and most common species of woodlouse native to the British Isles and Western and Northern Europe, growing to lengths of 16 mm and widths of 6 mm.
Porcellio laevis is a species of woodlouse in the genus Porcellio. As the species epithet laevis as well as the vernacular name "swift woodlouse" suggests, the species is capable of quick bursts of speed when provoked.
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.
Hyloniscus riparius is a species of woodlouse found in Central and Eastern Europe and subsequently introduced to North America. It is strongly associated with flood plains and can tolerate periods of up to eight weeks submerged under water. In North America, it was first found at St. John's, Newfoundland in 1951, and later in New York, New Jersey, Pennsylvania and North Carolina.
Androniscus dentiger, the rosy woodlouse or pink woodlouse is a species of woodlouse found from the British Isles to North Africa.
Ligidium hypnorum is a species of woodlouse found across Europe and western Asia. It is a fast-moving, active species that rarely grows longer than 9 mm (0.35 in). It is dark and shiny, and is similar in appearance to the common species Philoscia muscorum, and also the rarer Oritoniscus flavus. In Great Britain, it was first discovered at Copthorne Common, Surrey, in 1873, and most later records are also from South East England. It is considered a good indicator species for ancient woodland.
Armadillidium pictum is a species of woodlouse which occurs over most of Europe, except the Mediterranean Basin and Southeast Europe. In the British Isles, it is only known from a few sites, making it by some accounts, "Britain's rarest woodlouse". Since these sites are all remote from human habitation, in Cumbria and Powys, the species is thought to be native rather than introduced.
Hemilepistus reaumuri is a species of woodlouse that lives in and around the deserts of North Africa and the Middle East, "the driest habitat conquered by any species of crustacean, not including insects which are now known to be crustaceans pancrustacea". It reaches a length of 22 mm (0.87 in) and a width of up to 12 mm (0.47 in), and has seven pairs of legs which hold its body unusually high off the ground. The species was described in the Description de l'Égypte after the French Campaign in Egypt and Syria of 1798–1801, but was first formally named by Henri Milne-Edwards in 1840 as Porcellio reaumuri. It reached its current scientific name in 1930 after the former subgenus Hemilepistus was raised to the rank of genus.
Platyarthridae is a family of woodlice, containing the following genera:
Mesoniscus is a genus of woodlice, placed in its own family, Mesoniscidae, and section, Microcheta. It contains two species – Mesoniscus alpicolus and Mesoniscus graniger – that live in Central and Eastern Europe, mostly in and around caves.
Armadillidium atticum is a European species of woodlouse endemic to Greece. It is a relatively small species and belongs to the so called "Armadillidium insulanum complex".
Armadillidium sfenthourakisi is a European species of woodlouse endemic to Greece.
Armadillidium maniatum is a European species of woodlouse endemic to Greece.
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".
Trichorhina is a genus of woodlice in the family Platyarthridae.
Trichorhina acuta is a species of woodlouse, originally described by Araujo and Buckup in 1994. Distributed throughout Brazil, it can be found living synantropically, under dead plant matter or stones.
Trichorhina amazonica is a species of woodlouse, distributed throughout North-Eastern Brazil.
