Tylidae
Tylidae is a family of woodlice. It contains approximately 27 species, all but one in the genus ''Tylos'', the other being ''Helleria brevicornis''. Together with the family Ligiidae Ligiidae is a family (biology), family of woodlouse, woodlice, the only family in the infraorder Diplocheta. Its members are common on rocky shores, in similar habitats to those inhabited by species of the bristletail ''Petrobius'' and the crab ..., Tylidae appears to have diverged early from the remaining woodlouse families.

Micropezidae
The Micropezidae are a moderate-sized family of acalyptrate muscoid flies in the insect order Diptera, comprising about 500 species in about 50 genera and five subfamilies worldwide, (except New Zealand and Macquarie Island).McAlpine, D.K. (1998). Review of the Australian stilt flies (Diptera: Micropezidae) with a phylogenetic analysis of the family. ''Invertebrate Taxonomy'' 12:55–134. (with key to Australian species) They are most diverse in tropical and subtropical habitats, especially in the Neotropical Region. Insects in this family are commonly called stilt-legged flies, after their characteristically long legs. The fore legs are markedly smaller than the other pairs. Mostly, they are long-bodied, often black flies, usually with infuscated (darkened) wings. Wings are reduced in the genera '' Calycopteryx'' and entirely absent in the ant-like ''Badisis ambulans''. Description For terms see Morphology of Diptera Very slender, small to large (3–16 mm) flies, they h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helleria Brevicornis
''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. Description ''H. brevicornis'' is yellow-brown in colour and grows up to in length. This species has vestigial antennules, short antennae and a trapezoid telson. Each of its compound eyes consist of 19 ommatidia. Juveniles have bumps and setae while adults are almost smooth with light spots. In adults the plates of the posterior (pleonites) fuse with each other after moulting. Like all other members of the family Tylidae, it is capable of rolling up into a perfect ball with antennas tucked in. Distribution The species is found primarily in the oak forests of Corsica, from coastal areas up to an altitude of above sea level, and on Sardinia. It is also known to occur in isolated loca ...

Tylos (crustacean)
''Tylos'' is a genus of woodlice in the family Tylidae. There are at least 20 described species in ''Tylos''. All the species in this family can roll up into a perfect ball and live on sandy beaches. Species These 27 species belong to the genus ''Tylos'': * '' Tylos africanus'' Ferrara, 1974 * '' Tylos albidus'' Budde-Lund, 1879 * '' Tylos australis'' Lewis & Bishop, 1990 * '' Tylos capensis'' Krauss, 1843 * '' Tylos chilensis'' Schultz, 1983 * '' Tylos cilicius'' Verhoeff, 1941 * '' Tylos europaeus'' Arcangeli, 1938 * '' Tylos exiguus'' Stebbing, 1910 * '' Tylos granulatus'' Krauss, 1843 * '' Tylos granuliferus'' Budde-Lund, 1885 * '' Tylos latreillei'' Audouin, 1826 * '' Tylos madeirae'' Arcangeli, 1938 * '' Tylos maindroni'' Giordani Soika, 1954 * '' Tylos maindronii'' Soika, 1954 * '' Tylos marcuzzii'' Soika, 1954 * '' Tylos minor'' Dollfus, 1893 * '' Tylos neozelanicus'' Chilton, 1901 * '' Tylos niveus'' Budde-Lund, 1885 * '' Tylos nudulus'' Budde-Lund, 1906 * '' Tylos och ...

Woodlouse
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 like ...

James Dwight Dana
James Dwight Dana Royal Society of London, FRS FRSE (February 12, 1813 – April 14, 1895) was an American geologist, mineralogist, volcanologist, and zoologist. He made pioneering studies of mountain-building, volcano, volcanic activity, and the origin and structure of continents and oceans around the world. His zoological author abbreviation is Dana. Early life and career Dana was born February 12, 1813, in Utica, New York. His father was merchant James Dana (1780–1860) and his mother was Harriet Dwight (1792–1870). Through his mother he was related to the Dwight New England family of missionaries and educators including uncle Harrison Gray Otis Dwight and first cousin Henry Otis Dwight. He showed an early interest in science, which had been fostered by Fay Edgerton, a teacher in the Utica high school, and in 1830 he entered Yale College in order to study under Benjamin Silliman the elder. Graduating in 1833, for the next two years he was teacher of mathematics to midshi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 opini ...

Ligiidae is a family (biology), family of woodlouse, woodlice, the only family in the infraorder Diplocheta.
