Mymarilla wollastoni is a species of fairyflies endemic to the island of Saint Helena in the southern Atlantic. It is the only species classified under the genus Mymarilla. They are characterized by relatively smooth, shiny black bodies and densely hairy (setose) and domed forewings. They bear superficial resemblance to members of the genus Cremnomymar which inhabit similar habitats of remote wind-swept oceanic islands, but they are believed to be most closely related to the genus Stephanodes . They were first described by the English entomologist John Obadiah Westwood in 1879, from specimens collected from low-lying plants in Saint Helena. [1]
Saint Helena is a British overseas territory located in the South Atlantic Ocean. It is a remote volcanic tropical island 1,950 kilometres west of the coast of south-western Africa, and 4,000 kilometres (2,500 mi) east of Rio de Janeiro in South America. It is one of three constituent parts of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha.
John Obadiah Westwood was an English entomologist and archaeologist also noted for his artistic talents. He published several illustrated works on insects and antiquities. He was among the first entomologists with an academic position at Oxford University. He was a natural theologian, staunchly anti-Darwinian, and sometimes adopted a quinarian viewpoint. Although he never travelled widely, he described species from around the world on the basis of specimens, especially of the larger, curious, and colourful species, obtained by naturalists and collectors in England.
The Governor of Saint Helena is the representative of the British monarch in the United Kingdom's overseas territory of Saint Helena, Ascension and Tristan da Cunha. The Governor is appointed by the monarch on the official advice of Her Majesty's Government (HMG).
The Saint Helena rail was a large flightless rail from Saint Helena. It became extinct in the early 16th century.
The Saint Helena olive is an extinct species of flowering plant. It is the only member of the genus Nesiota. It was endemic to the island of Saint Helena in the South Atlantic Ocean. Despite its name, it is unrelated to the true olive, but is instead a member of the family Rhamnaceae, the family which contains buckthorns and jujube. The last remaining tree in the wild died in 1994, and the last remaining individual in cultivation died in December 2003, despite conservation efforts. It is thus a prime example of recent plant extinction. The Saint Helena olive belongs to the tribe Phyliceae, which are mostly endemic to Southern Africa.
Melanodendron is a genus of trees in the family Asteraceae, with only one species, Melanodendron integrifolium, native to the island of Saint Helena. It is related to the Saint Helenan gumwoods and is the commonest of the remaining cabbage tree species of Saint Helena, although it is considered endangered due to the restricted population size.
Dicksonia arborescens, the Saint Helena tree fern, is a characteristic plant of the "tree fern thicket" vegetation of the highest parts of the central ridge of the island of Saint Helena. It is the type species of the genus Dicksonia.
Trochetiopsis erythroxylon, the Saint Helena redwood, is a species of plant, now extinct in the wild. It was formerly abundant enough in the upland parts of the island of Saint Helena for early settlers in the 17th century to use the timber to make their homes. It became extinct in the 1950's due to deforestation as it's habitat was cleared to make way for pasture, timber and fuel.
The flowering plant genus Trochetiopsis consists of two extant and one extinct species endemic to the island of Saint Helena. They were formerly placed in the family Sterculiaceae, but this is included in the expanded Malvaceae in the APG and most subsequent systematics.
Commidendrum robustum, the Saint Helena gumwood, is a species of tree endemic to Saint Helena, Ascension and Tristan da Cunha. Though it is now comparatively rare, it was once one of the most abundant trees of mid-elevations of the island of Saint Helena in the South Atlantic Ocean. A small tree to 7–8 m, it was cut extensively for fuel in the early years of settlement of the island by the English East India Company. It has given its name to certain placenames on the island such as "Gumwoods". It is one of several species in the endemic genus Commidendrum.
Mellissia was formerly a monotypic genus in the family Solanaceae with the single species, Mellissia begoniifolia, endemic to the island of Saint Helena. It was named by Joseph Dalton Hooker in honour of John Charles Melliss, a 19th-century engineer and amateur naturalist who worked on Saint Helena. The plant is now known correctly as Withania begoniifolia (Roxb.) Hunz. & Barboza, the genus Mellissia having been subsumed in the genus Withania.
Petrobium is a genus in the family Asteraceae.
Nesohedyotis is a genus of flowering plants endemic to the island of Saint Helena in the South Atlantic Ocean. It in the family Rubiaceae.
Saint Helena, Ascension Island and Tristan da Cunha, as well the other uninhabited islands nearby, are a haven for wildlife in the middle of the Atlantic Ocean. The islands are or were home to much endemic flora and fauna, especially invertebrates, and many endemic fish species found in the reef ecosystems off the islands. The islands have been identified by BirdLife International as Important Bird Areas for both their endemic landbirds and breeding seabirds.
Storrs Lovejoy Olson was an American biologist and ornithologist who spent his career at the Smithsonian Institution, retiring in 2008. One of the world's foremost avian paleontologists, he was best known for his studies of fossil and subfossil birds on islands such as Ascension, St. Helena and Hawaii. His early higher education took place at Florida State University in 1966, where he obtained a B.A. in biology, and the University of Florida, where he received an M.S. in biology. Olson's doctoral studies took place at Johns Hopkins University, in what was then the School of Hygiene and Public Health. He was married to fellow paleornithologist Helen F. James.
Lachanodes is a genus of plants in the groundsel tribe of the sunflower family. The plants are native to certain islands in the South Atlantic.
Ascension Island is an isolated volcanic island, 7°56′ south of the Equator in the South Atlantic Ocean. It is about 1,000 miles (1,600 km) from the coast of Africa and 1,400 miles (2,300 km) from the coast of South America. It is governed as part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, of which the main island, Saint Helena, is around 800 miles (1,300 km) to the southeast. The territory also includes the sparsely populated Tristan da Cunha archipelago, 2,300 miles (3,700 km) to the south, about halfway to the Antarctic Circle.
Saint Helena, Ascension and Tristan da Cunha is a British Overseas Territory located in the South Atlantic and consisting of the island of Saint Helena, Ascension Island and the archipelago of Tristan da Cunha including Gough Island. Its name was Saint Helena and Dependencies until 1 September 2009, when a new constitution came into force giving the three islands equal status as three territories, with a grouping under the Crown.
Sphaerophoria beattiei is a species of hoverfly belonging to the genus Sphaerophoria. It is endemic to the island of Saint Helena in the South Atlantic. It was originally considered the only member of the genus Loveridgeana but was found to be nested within Sphaerophoria in a DNA based phylogenetic analysis. It is most closely related to species found in South Africa. Almost nothing is known of its biology other than it pollinated now extinct flora on Saint Helena including the Saint Helena olive.
The Saint Helena butterflyfish, also known as the cunningfish, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the Atlantic Ocean around the islands of St Helena and Ascension Island.
