Question: Laminacauda insulana is a species of sheet weaver found in Tristan da Cunha, colloquially Tristan, is the name of both a remote group of volcanic islands in the south Atlantic Ocean and the main island of that group, the nearest continental land, is which country  ?
Context: Laminacauda tristani is a species of sheet weaver found in Tristan da Cunha.  It was described by Millidge in 1985. Tristan da Cunha is an archipelago of five islands in the southern Atlantic Ocean, the largest of which is the island of Tristan da Cunha itself and the second-largest the remote bird haven Gough Island.  It forms part of a wider territory called Saint Helena, Ascension and Tristan da Cunha which includes Saint Helena and Ascension Island. Gough Island , also known historically as Gonçalo Álvares (after the Portuguese explorer) or mistakenly as Diego Alvarez, is a volcanic island in the South Atlantic Ocean.  It is a dependency of Tristan da Cunha and part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha.  It is uninhabited except for the personnel of a weather station (usually six people) which the South African National Antarctic Programme has maintained continually on the island since 1956.  It is one of the most remote places with a constant human presence. Jasus paulensis, also commonly known as the St Paul rock lobster, is a species of spiny lobster found in the waters around Saint Paul Island in the southern Indian Ocean and around Tristan da Cunha in the southern Atlantic Ocean.  At one time the rock lobsters on Tristan da Cunha were believed to be a separate species known as the Tristan rock lobster ("Jasus tristani"), but the use of mitochondrial DNA sequencing has shown them to be identical.  Some authorities, for example the IUCN, retain them as separate species.  The Tristan rock lobster features on the coat of arms and the flag of Tristan da Cunha. Laminacauda maxima is a species of sheet weaver found in Tristan da Cunha.  It was described by Millidge in 1985. The Administrator of Tristan da Cunha is the head of government and representative of the Governor of Saint Helena in Tristan da Cunha.  The role of the Administrator is to chair the territory's Island council which consists of 8 elected members and 3 appointed members.  As a part of the British overseas territory of Saint Helena, Ascension and Tristan da Cunha, the head of state is Elizabeth II, with the Governor of Saint Helena appointed by the British government to act as her local representative.  However, as Tristan da Cunha is over 1,350 miles away from Saint Helena, an Administrator is appointed as the Governor's representative on the Island.  Previously the Administrator also acted as the local Magistrate, but the appointment is to be transferred to a non-member of the executive or legislative branches of government. Tristan da Cunha ( ), colloquially Tristan, is the name of both a remote group of volcanic islands in the south Atlantic Ocean and the main island of that group.  It is the most remote inhabited archipelago in the world, lying 2000 km from the nearest inhabited land, Saint Helena, and 2400 km from the nearest continental land, South Africa.  It is 3360 km from South America.  The territory consists of the main island, named Tristan da Cunha, which has a north–south length of 11.27 km and an area of 98 km2 , along with the smaller, uninhabited Nightingale Islands and the wildlife reserves of Inaccessible and Gough islands.  As of January 2017, the main island has 262 permanent inhabitants.  The other islands are uninhabited, except for the personnel of a weather station on Gough Island. Ascension Island is an isolated volcanic island in the equatorial waters of the South Atlantic Ocean, around 1600 km from the coast of Africa and 2250 km from the coast of Brazil, which is roughly midway between the horn of South America and Africa.  It lies 7°56' South of the Equator.  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 1300 km to the southeast.  The territory also includes the sparsely populated Tristan da Cunha archipelago, some 3730 km to the south, about halfway to the Antarctic Circle. Laminacauda insulana is a species of sheet weaver found in Tristan da Cunha.  It was described by Millidge in 1985. Laminacauda luscinia is a species of sheet weaver found in Tristan da Cunha.  It was described by Millidge in 1985.
