Arthurdendyus Latissimus
''Arthurdendyus'' is a genus of land planarians from New Zealand. It was erected in 1999 and includes the invasive species ''Arthurdendyus triangulatus'', known as the New Zealand flatworm. Description Species of ''Arthurdendyus'' are characterized by a bell-shaped pharynx and ovaries placed laterally to the male copulatory apparatus, while most land planarians species have ovaries located much more anteriorly, usually close to the brain or to the pharynx. Other characteristic shared with closely related genera, such as ''Artioposthia'' and ''Newzealandia'', is the presence of adenodactyls in the copulatory apparatus. Etymology The name ''Arthurdendyus'' honors the English zoologist Arthur Dendy who described many land planarians from Australia and New Zealand. Species The genus ''Arthurdendyus'' includes the following species: *'' Arthurdendyus albidus'' Jones & Gerard, 1999 *'' Arthurdendyus australis'' (Dendy, 1894) *'' Arthurdendyus latissimus'' (Dendy, 1896) *'' Arth ...

Arthurdendyus Triangulatus
The New Zealand flatworm (''Arthurdendyus triangulatus'') is a large land flatworm native to New Zealand. It can vary from 5 mm in length when hatched to approximately in mature adults. The New Zealand flatworm is considered an invasive species in parts of Europe. This species is included since 2019 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union. Description The ventral surface of the flatworm is a pale buff colour while the dorsal surface is dark brown. Young flatworms vary in colour from white to pale orange and develop their adult colouration as they grow. During the day, flatworms can be found resting on the surface of soil underneath objects in close contact with the ground. They may also be found beneath the soil surface hunting for earthworms. Reproduction involves the prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geoplanidae
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. They lack water-retaining mechanisms and are therefore very sensitive to humidity variations of their environment. Because of their strict ecological requirements, some species have been proposed as indicators of the conservation state of their habitats. They are generally animals with low vagility (dispersal ability) and with very specific habitat requirements, so they can be also used to accurately determine the distribution of biogeographic realms. Today the fauna of these animals is being studied to select conservation priorities in the Atlantic rainforest in Brazil. At the other extreme, one species in this family, ''Platydemus manokwari'' has become an invasive species in both disturbed and wild habitats in the ...

Arthurdendyus Vegrandis
''Arthurdendyus'' is a genus of land planarians from New Zealand. It was erected in 1999 and includes the invasive species ''Arthurdendyus triangulatus'', known as the New Zealand flatworm.

Other characteristic shared with closely related genera, such as ''Artioposthia'' and ''Newzealandia'', is the presence of adenodactyls in the copulatory apparatus.

Newzealandia
''Newzealandia'' is a genus of land planarian Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive proper ...s from New Zealand. Description Species of the genus ''Newzealandia'' are characterized by a copulatory apparatus that lacks a penis papilla and has a series of accessory glands embedded into the wall of the atrial cavity. Those glands are similar to the adenodactyls found in the closely related genus '' Artioposthia'', the main difference being that adenodactyls project into the atrial cavity. Etymology The name ''Newzealandia'' comes from New Zealand, the country in which the species of the genus are found. Species The genus ''Newzealandia'' includes the following species: *'' Newzealandia agricola'' (Dendy, 1895) *'' Newzealandia graffii'' (Dendy, 1895) *'' Newzealandia inaequabil ...

Arthur Dendy
Arthur Dendy (20 January 1865, in Manchester – 24 March 1925, in London) was an English zoologist known for his work on marine sponges and the terrestrial invertebrates of Victoria, Australia, notably including the "living fossil" ''Peripatus''. He was in turn professor of zoology in New Zealand, in South Africa and finally at King's College London. He was a Fellow of the Royal Society. Family life Dendy's parents were John Dendy, a silk fabric maker of Manchester, and Sarah Beard, daughter of John Relly Beard. His sisters included Mary Dendy and Helen Bosanquet. He married Ada Margaret Courtauld on 5 December 1888. They had four children, three daughters—including the artist Vera Ellen Poole (1890–1965)—and one son. Career He was educated in zoology at Owens College, Manchester, gaining his M.Sc. in 1887 and his D.Sc. in 1891. He worked on part of the report of the Challenger expedition (1872–1876), describing monaxonid sponges. In 1888 he moved to the Univers ...

Artioposthia ''Artioposthia'' is a genus of land planarians from the Australasian and Indo-Pacific countries. Several species have also been introduced in Europe. Description Species of ''Artioposthia'' are characterized by a cylindrical pharynx and ovaries placed anteriorly to the male copulatory apparatus, close to the brain or to the pharynx. The copulatory apparatus has a series of paired glandular organs called adenodactyls. ''Artioposthia'' is very similar to the closely related genus ''Arthurdendyus'', the main difference being the position of the ovaries and the shape of the pharynx. Species The genus ''Artioposthia'' includes the following species: *''Artioposthia adelaidensis'' (Dendy, 1892) *''Artioposthia |
