Apterygon Mirum
''Apterygon'' is a genus of louse. It is endemic to New Zealand and is an ectoparasite of kiwi birds (''Apteryx''). Theresa Clay circumscribed the genus in 1961. In 1947, she had referred to this genus as "New Genus D", but it was not formally named as she needed to confirm the host of her specimen as well as additional material. Description ''Apterygon'' heads lack preocular slits and the female genital chamber has a cellular circular structure. They lack eyes, have a reduced hypopharynx and a well developed postnotum. Species , four species are recognized in this genus. '' A. mirum'', the type species of this genus, was described by Clay in the same paper which named the genus ''Apterygon''. The holotype came from a North Island brown kiwi which was killed by a car in Opotiki, New Zealand. It is found in New Zealand's North Island. Clay described a second species for this genus, '' A. hintoni'', in 1966. Its type host was a great spotted kiwi and its type locality was Nelso ...

Theresa Clay
Theresa Rachel "Tess" Clay (7 February 1911 – 17 March 1995) was an English entomologist. She was introduced to zoology by her older relative, the ornithologist and adventurer Richard Meinertzhagen, with whom she had an unusually close relationship. She became the world's expert on Mallophaga, or chewing lice; however, her work is cast into question by her suspected role in Meinertzhagen's many scientific frauds. During and immediately after World War II, she worked with Victor Rothschild at MI5. Early life and family Clay was born on 7 February 1911, to Sir George Felix Neville Clay, 5th Baronet, one of the Clay Baronets, and Rachel Hobhouse Clay. Clay had four siblings, older sisters Margaret and Janet, older brother Sir Henry Clay, 6th Baronet, Henry, and younger brother Anthony. Clay's family lived at No. 18 Kensington Park Gardens, Notting Hill, London, and she attended at St Paul's Girls' School. Relationship with Richard Meinertzhagen When Clay was eleven years ol ...

Parasites Of Birds
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an ect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect Genera
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lice
Louse ( : lice) is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research. Lice are obligate parasites, living externally on warm-blooded hosts which include every species of bird and mammal, except for monotremes, pangolins, and bats. Lice are vectors of diseases such as typhus. Chewing lice live among the hairs or feathers of their host and feed on skin and debris, while sucking lice pierce the host's skin and feed on blood and other secretions. They usually spend their whole life on a single host, cementing their eggs, called nits, to hairs or feathers. The eggs hatch into nymphs, which moult three times before becoming fully grown, a process that takes about four weeks. Genetic evidence indicates that lice are a highly modified lineage of Psocoptera (now called Ps ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rallicola
''Rallicola'' is a genus of chewing louse. It is an ectoparasite of rails and other birds. It was named by Thomas Harvey Johnston and Launcelot Harrison in 1911. There are two subgenera aside from the nominotypical subgenus: ''Aptericola'', whose species are found on kiwi birds, and ''Huiacola'', a monospecific subgenus consisting of ''Rallicola extinctus'', once found on the huia. Taxonomic history In 1866, Ferdinand Rudow circumscribed the Philopteridae genus '' Trabeculus'' with ''Trabeculus schillingi'' as its type species. In 1870, he created a new genus, ''Oncophorus'' with the same type species, making it an objective junior synonym of ''Trabeculus''. In 1880, Édouard Piaget added more species to ''Oncophorus''. He listed the author citation as "Rud." for Rudow in 1880, but as "m." for ' to indicate himself in 1885. Thomas Harvey Johnston and Launcelot Harrison created a new genus name, ''Rallicola'', in 1911. A new name was needed as ''Oncophorus'' and ''Oncophorus'' ...

Kiwi (bird)
Kiwi ( ) are flightless birds endemic to New Zealand of the order Apterygiformes. The five extant species fall into the family Apterygidae () and genus ''Apteryx'' (). Approximately the size of a domestic chicken, kiwi are by far the smallest living ratites (which also include ostriches, emus, rheas and cassowaries). However, the ratite group is polyphyletic, and cladistically also includes tinamous, which can also be of moderate size. Members of this expanded group are known as paleognaths. DNA sequence comparisons have yielded the conclusion that kiwi are much more closely related to the extinct Malagasy elephant birds than to the moa with which they shared New Zealand. There are five recognised species, four of which are currently listed as vulnerable, and one of which is near-threatened. All species have been negatively affected by historic deforestation, but their remaining habitat is well-protected in large forest reserves and national parks. At present, the greates ...

Okarito Kiwi
The Okarito kiwi (''Apteryx rowi''), also known as the rowi or Okarito brown kiwi, is a member of the kiwi family Apterygidae, described as new to science in 2003. The species is part of the brown kiwi complex, and is morphologically very similar to other members of that complex. It is found in a restricted area of the Ōkārito forest on the West Coast of New Zealand's South Island, and has a population of only about 600 birds. Taxonomy The Okarito kiwi is a monotypic species, i.e. there are no recognised subspecies. The genus name '' Apteryx'' stems from the Greek "without wings". Originally assumed to be the same species as the Southern brown kiwi ''A. australis'', DNA testing shows that the possible split off from this species was 8.2 million years ago, and the split from their closest relatives, the Northern Island brown kiwi '' A. mantelli'' was around 6.2 million years ago. This bird is a ratite and has similarities to the others (emu, ostrich, rhea, cassowary). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Little Spotted Kiwi
The little spotted kiwi or little grey kiwi (''Apteryx owenii'') is a small flightless bird in the kiwi family Apterygidae. It is the smallest species of all five kiwis, at about , about the size of a bantam. It is endemic to New Zealand, and in pre-European times occurred in both main islands, but is now restricted to a number of small offshore islands and mainland reserves protected by pest-exclusion fences. Taxonomy The little spotted kiwi is a ratite and belongs to the Apterygiormes Order, and the Apterygidae Family. Their binomial name ''Apteryx owenii'' breaks down to ''without wings'' and ''owenii'' which is named after Sir Richard Owen. Today, only the nominate subspecies ''A. o. owenii'' exists. A subspecies, ''A. o. iredalei,'' from the North Island has been described. It became extinct in the late 19th century, but the subspecies isn't universally accepted as valid. The little spotted kiwi was first described in 1847 by John Gould from a specimen obtained by Frederick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Island Brown Kiwi
The southern brown kiwi, tokoeka, or common kiwiDavies, S. J. J. F. (2003) (''Apteryx australis'') is a species of kiwi from South Island, New Zealand. Until 2000 it was considered conspecific with the North Island brown kiwi, and still is by some authorities. Taxonomy ''Apteryx australis'' is based on Greek and Latin. ''Apteryx'' means "''A-''" without "''pterux''" wings, and "''australis''" from "''auster''" the south wind, and "''-alis''" relating to. The southern brown kiwi belongs to the kiwi family and it is a ratite, and a member of the order Apterygiformes. Like all ratites, its sternum has no keel, it is flightless, and it has a distinctive palate. The holotype specimen of ''Apteryx australis'' ShawNat. Miscell., 24,1813, pl1057 is held in the collections of National Museums Liverpool at World Museum, with accession number NML-VZ D180. The specimen was collected by Captain Barclay at Dusky Sound, South Island, New Zealand and came to the Liverpool national collection ...
