Agnaridae
Agnaridae is a family of woodlice. They were formerly considered part of the Trachelipodidae, but were moved from that family to Porcellionidae Porcellionidae is a terrestrial family of the order Isopoda. This family contains 530 species, found on every continent except Antarctica. The ventral plate of the thoracic exoskeleton flare out slightly over the legs. This "flare" is called t ... in 1989, and then placed as a separate family in 2003. References Further reading *Schotte, M.; Kensley, B. F.; Shilling, S. (1995 onwards).

Woodlice
A woodlouse (plural woodlice) is an isopod crustacean from the polyphyleticThe current consensus is that Oniscidea is actually triphyletic suborder Oniscidea within the order Isopoda. They get their name from often being found in old wood. The first woodlice were marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. They have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape (conglobate) as a defensive mechanism; others have partial rolling ability, but most cannot conglobate at all. Woodlice have a basic morphology of a segmented, dorso-ventrally flattened body with seven pairs of jointed legs, specialised appendages for respiration and ...

Hemilepistus
''Hemilepistus'' is a genus of woodlouse, woodlice, created by Gustav Henrik Andreas Budde-Lund, G. H. A. Budde-Lund in 1879 as a subgenus of ''Porcellio'', but raised to the rank of genus by Karl Wilhelm Verhoeff in 1930. It contains the following species: *''Hemilepistus aphganicus'' Borutzky, 1958 *''Hemilepistus buddelundi'' Borutzky, 1945 *''Hemilepistus communis'' Borutzky, 1945 *''Hemilepistus crenulatus'' (Pallas, 1771) *''Hemilepistus cristatus'' Budde-Lund, 1885 *''Hemilepistus elongatus'' Budde-Lund, 1885 *''Hemilepistus fedtschenkoi'' (Uljanin, 1875) *''Hemilepistus heptneri'' Borutzky, 1945 *''Hemilepistus klugii'' (Brandt, 1833) *''Hemilepistus magnus'' Borutzky, 1945 *''Hemilepistus nodosus'' Budde-Lund, 1885 *''Hemilepistus pavlovskii'' Borutzky, 1954 *''Hemilepistus reaumuri'' (Milne-Edwards, 1840) *''Hemilepistus reductus'' Borutzky, 1945 *''Hemilepistus rhinoceros'' Borutzky, 1958 *''Hemilepistus ruderalis'' (Pallas, 1771) *''Hemilepistus russonovae'' Borutzky, ...

Arthropod Systematics & Phylogeny
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder- ...

Porcellionidae
Porcellionidae is a terrestrial family of the order Isopoda. This family contains 530 species, found on every continent except Antarctica. The ventral plate of the thoracic exoskeleton flare out slightly over the legs. This "flare" is called the ''epimeron''. The uropods, antenna-like structures at the back of the specimen, are flattened out and spearlike, and extend beyond the last exoskeletal plate. Genera The family contains 19 genera, and two further genera ('' Inchanga'' and ''Mahehia'') may be included. *'' Acaeroplastes'' Verhoeff, 1918 *'' Agabiformius'' Verhoeff, 1908 *'' Atlantidium'' Arcangeli, 1936 *'' Brevurus'' Schmalfuss, 1986 *'' Caeroplastes'' Verhoeff, 1918 *'' Congocellio'' Arcangeli, 1950 *'' Dorypoditius'' Verhoeff, 1942 *'' Leptotrichus'' Budde-Lund, 1885 *'' Lucasius'' Kinahan, 1859 *''Mica Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely th ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Hemilepistus Reaumuri
''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". It reaches a length of and a width of up to , and has seven pairs of legs which hold its body unusually high off the ground. The species was described in the ' 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. ''H. reaumuri'' occurs at great population densities and fills an important niche in the desert ecosystem. It feeds on plant leaves, obtains most of its water from moisture in the air and sand, and is in turn an important prey item for the scorpion '' Scorpio maurus''. ''H. reaumuri'' is only able to survive in such arid conditions because it has developed parental care ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
