Psephotellus
''Psephotellus'' is a genus of medium sized Australian parrots. Four species found across the country are recognised, one is presumed to have become extinct. Description All species show considerable sexual dimorphism. These species have traditionally been placed in the genus ''Psephotus'' along with the red-rumped parrot, but a molecular study analysing nuclear and mitochondrial DNA found that the red-rumped parrot was an early offshoot in a clade of several genera of broad-tailed parrot, with the other species nested deeply within. Taxonomy The genus was first proposed by Gregory Mathews Gregory Macalister Mathews CBE FRSE FZS FLS (10 September 1876 – 27 March 1949) was an Australian-born amateur ornithologist who spent most of his later life in England.

Broad-tailed Parrot
A broad-tailed parrot is any of about 35–40 species belonging to the tribe Platycercini. The members of the tribe are small to medium in size, and all are native to Australasia, Australia in particular, but also New Zealand, New Caledonia, and nearby islands.

Psephotellus Dissimilis
The hooded parrot (''Psephotellus dissimilis'') is a species of parrot native to the Northern Territory in Australia. It is found in savannah and open woodland and is one of two extant species in its genus that breed in termite mounds. It has declined from much of its original range. Taxonomy One of three species known as antbed parrots, the hooded parrot is closely related to (and sometimes considered a subspecies of) the golden-shouldered parrot (''Psephotellus chrysopterygius''). A genetic study revealed its ancestors most likely diverged from ancestors of the latter species in the late Miocene or early Pliocene at the conclusion of the 'Hill Gap'. Norwegian naturalist Robert Collett described the hooded parrot in 1898. Its species name is the Latin word ''dissimilis'' "different" and either refers to its sexual dimorphism or its different appearance from its closest relative. Black-hooded parrot is an alternative name. Description The hooded parrot is a medium-sized pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mulga Parrot
The mulga parrot (''Psephotellus varius'') is endemic to arid scrublands and lightly timbered grasslands in the interior of southern Australia. The male mulga parrot is multicolored, from which the older common name of many-coloured parrot is derived. Taxonomy The mulga parrot was given its current scientific name of ''Psephotellus varius'' by American zoologist Austin Hobart Clark in 1910, after its name ''Psephotus multicolor'' was ruled invalid as the original combination (''Psittacus multicolor'') had been used for another species. Gregory Mathews proposed the name ''Psephotus dulciei'' in 1911 for the same reason, unaware of Clark's proposal, which was published earlier and hence had priority. Mathews described two additional subspecies of mulga parrot in 1912: ''P. varius rosinae'', from a specimen collected from Yorke Peninsula, noting that it had less red on the abdomen and its upper breast was a darker green, and ''P. varius exsul'' from a specimen from Mount Magnet in ...

Psephotellus Chrysopterygius
The golden-shouldered parrot (''Psephotellus chrysopterygius''), also known as the alwal, is a rare bird of southern Cape York Peninsula, in Queensland, Australia. A small parrot related to the more common red-rumped parrot (''Psephotus haematonotus''), the hooded parrot (''P. dissimilis'') of the Northern Territory and the extinct paradise parrot of Queensland and New South Wales. Description The golden-shouldered parrot is 23–28 cm long and weighs 54–56 g. The adult male is mainly blue and has a characteristic yellow over the shoulder area. It has a black cap and pale yellow frontal band. It has an extended dark salmon pink lower belly, thighs and undertail-coverts. It has a grey-brown lower back. Adult females are mainly dull greenish-yellow, and have a broad cream bar on the underside of the wings. The head in older females has a charcoal grey cap. The feathers of the vent area are a pale salmon pink. Juveniles are similar to the adult female though newly fledge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psephotus Varius -Gluepot Reserve -South Australia-8
The red-rumped parrot (''Psephotus haematonotus''), also known as the red-backed parrot or grass parrot, is a common bird of south-eastern Australia, particularly in the Murray-Darling Basin. Taxonomy The red-rumped parrot was described by John Gould in 1838 as ''Platycercus haematonotus'' from a specimen collected in New South Wales. He felt it was intermediate between the genera '' Platycercus'' and ''Nanodes'', placing it in the former. He gave it its species name on account of its red rump. ould's species description appears in the meeting notes without a title./ref> It is the type species for the genus ''Psephotus''. It was long presumed to be closely related to the mulga parrot, however analysis of multiple genetic material shows it to be an early offshoot of a group containing the genera '' Platycercus'' and '' Barnardius''. Hence all other species in the genus have been moved to the new genus ''Psephotellus'', leaving the red-rumped parrot as the sole member in the no ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregory Mathews
Gregory Macalister Mathews Order of the British Empire, CBE FRSE FZS FLS (10 September 1876 – 27 March 1949) was an Australian-born amateur ornithologist who spent most of his later life in England. Life He was born in Biamble, New South Wales, Biamble in New South Wales the son of Robert H. Mathews. He was educated at The King's School, Parramatta. Mathews made his fortune in mining shares, and moved to England in 1902. In 1910 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were William Eagle Clarke, Ramsay Heatley Traquair, John Alexander Harvie-Brown and William Evans (naturalist), William Evans. Ornithology Mathews was a controversial figure in Australian ornithology. He was responsible for bringing trinomial nomenclature into local taxonomy, however he was regarded as an extreme splitter. He recognised large numbers of subspecies on scant evidence and few notes. The extinct Lord Howe Pigeon was described by Mathews in 1915, using a painting as ...
