Trichorhina amazonica is a species of woodlouse, distributed throughout North-Eastern Brazil. [1]
It is described as being brown with small brown spots on its head. The entire isopod is covered in fan-like scales, with the male reported as being 3.03 mm long and 1.24 mm wide. Its eyes have 10 ommatids and have a dark brown colour. The anterior margins of pereonite one reach the eyes. Its pleon outline is continuous with the pereon and the telson is reported to be sub-triangular and slightly concave. The antennae can reach pereonite two if stretched. The anennulae are each fitted with five aesthetascs. Due to its relatively high amount of ommatids it is theorized to be a more primitive member of the Trichorhina genus. [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.
Ligia oceanica, the sea slater, common sea slater, or sea roach, is a woodlouse, living in the littoral zone—rocky seashores of the European North Sea and Atlantic coastlines.
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.
Archaeoniscus is a genus of prehistoric isopods that first appeared during the Bajocian stage of the Middle Jurassic. It is a widespread genus with a paleogeographic distribution encompassing the continental margin environments of the central Atlantic Ocean and the western Tethys Ocean. Fossils of Archaeoniscus suggest that this genus lived in diverse aquatic habitats, including the marine, paralic, and freshwater environments. While earlier descriptions suggested that it may have had an ectoparasitic association with fishes, some researchers argue that at least two species, A. aranguthyorum and A. coreaensis, lived a benthic free-living lifestyle based on morphological characteristics that are either unsuitable for or unrelated to parasitic behavior.
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.
Androniscus dentiger, the rosy woodlouse or pink woodlouse is a species of woodlouse found from the British Isles to North Africa.
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.
Armadillidium klugii is a lesser-known, rare Balkan, Dalmatia-based species of woodlouse, most distinguished by its colouration which resembles the red markings of the Mediterranean black widow Latrodectus tredecimguttatus. This is probably a kind of mimicry, to ward off predators that mistake the harmless animal for a venomous spider.
Exosphaeroma amplicauda is a species of marine isopod of the family Sphaeromatidae.
Helleria brevicornis, the sole species of the monotypic genus Helleria, is a terrestrial woodlouse endemic to the islands and coastal regions of the northern Tyrrhenian sea. H. brevicornis is of interest due to its endemism, unique ecology and basal position in the suborder Oniscidea.
Armadillidium sfenthourakisi is a European species of woodlouse endemic to Greece.
Armadillidium maniatum is a European species of woodlouse endemic to Greece.
Armadillidium pieperi is a European species of woodlouse endemic to Greece. It is a relatively medium-sized species that probably belongs to the so-called "Armadillidium fossuligerum complex".
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.
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 argentina is a species of woodlouse found in southern Brazil and central eastern Argentina. It can be found living synantropically under stones or leaves.
