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 ...

Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are predators or parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two distinct groups of arachnids ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific nam ...

Ameroseiidae
The family Ameroseiidae is one of the three families of mites under the superfamily Ascoidea. There are about 12 genera and more than 130 described species in Ameroseiidae. The family has a worldwide distribution. Description Ameroseiidae can be recognised by: a well-sclerotised and often strongly ornamented dorsal shield; usually 27-30 pairs of setae on the dorsal shield and setae ''J5'' always absent; the sternal shield often reduced to 2 pairs of setae with ''st3'' on shield or on platelets; the corniculi often toothed; the chelicerae sometimes with a membranous lobe; and the tectum usually simple, smoothly (rarely toothed) triangular or weakly to strongly mucronate. Leg chaetotaxy - the arrangements of setae on the legs - varies among species and genera, making this feature useful for classification. Ecology Ameroseiids occur in many habitats including forest litter, garden mulch, dead wood and associated fungi, flowers, animal nests, tree hollows, humid soils and ...

Ascidae
Ascidae is a family of mites in the order Mesostigmata. Description Ascidae are mites characterised by: seta ''st4'' usually on unsclerotised cuticle, peritrematic shield broadly connected to exopodal shield beside coxa IV, fixed cheliceral digit with setiform ''pilus dentilis'' and movable cheliceral digit usually with two teeth, sternal shield with three pairs of lyrifissures and the third pair usually on the shield's posterior margin, genital shield truncate to convex posteriorly (tapering in some ''Antennoseius''), with an anal shield bearing only circumanal setae (rare) or a ventrianal shield bearing additionally up to seven pairs of setae, and spermathecal apparatus laelapid-type. This family is morphologically similar to Blattisociidae and Melicharidae, and these families were formerly included within Ascidae. Life cycle The life cycle of Ascidae consists of the stages egg, larva, protonymph, deutonymph and adult. Each stage has a duration measurable in days. T ...

Melicharidae
''Melicharidae'' is a family of mites in the order Mesostigmata. Description Melicharidae are mites characterized by: podonotal and opisthonotal shields usually fused; the third pair of sternal lyrifissures (''iv3'') situated off sternal shield (rarely absent) and usually on metasternal plates; peritrematic shield free posteriorly from, or narrowly fused with, exopodal shield beside coxa IV (except ''Orthadenella''); fixed cheliceral digit usually with a hyaline lobe instead of a setiform ''pilus dentilis,'' and movable cheliceral digit usually with a pointed process (mucro) on mid-ventral face; genital shield usually gently rounded posteriorly; anal shield usually oval or elliptical, bearing only circumanal setae; and female spermathecal apparatus laelapid-type. Ecology Melicharidae are free-living mites found in various habitats including soil, leaf litter, plants (e.g. bromeliads, pineapple flowers and false bird-of-paradise), rotten wood, stored products, seaweeds, an ...
