Gromphadorhina Oblongonota
''Gromphadorhina oblongonota'' is one of four roach species in the genus '' Gromphadorhina'', which is one of several genera collectively known as hissing cockroaches; like all members of the tribe Gromphadorhini, they are from the island of Madagascar Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa .... They are common in the pet trade, where they are known as "wide-horned hissers" and their scientific name is frequently misspelled as either ''oblongata'' or ''oblongonata''. This species is difficult to distinguish from the common '' G. portentosa'' and is commonly confused with it, although ''oblongonota'' tends to be significantly larger and somewhat darker than ''portentosa''. As pets All four known ''Gromphadorhina'' species are widely kept as exotic pets, with ''G. portentos ...

In the older literature, the name is sometimes misspelled as "Gromphadorrhina” As pets All four ''Gromphadorhina'' species are widely kept as exotic pets, where the most well-known species is the Madagascar hissing cockroach The Madagascar hissing cockroach (''Gromphadorhina portentosa''), also known as the hissing cockroach or simply hisser, is one of the largest species of cockroach, reaching at maturity. They are native to the island of Madagascar, which is off ..., (''G. portentosa''), though this is debatable as at least two other species in the genus are commonly confused with it; '' G. oblongonota'' and '' G. picea''.Delfosse, E.

Gromphadorhini
Gromphadorhini is a Tribe (biology), tribe of large, flightless, wood-inhabiting cockroaches comprising 20 known species in 6 gener all but one from the island of Madagascar; the one exception being from Europa Island just off the coast of Madagascar. They are collectively known as hissing cockroaches, capable of producing sound by forcing air through their abdominal Spiracle (arthropods), spiracles, and many species are popular in the pet trade, especially the species commonly called "the Madagascar hissing cockroach", ''Gromphadorhina portentosa''. Remarkably, despite their size, 9 of the 20 known species of hissing roaches were not recognized until recently, having only been described in 1973.C. van Herrewege. 1973.

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Madagascar Hissing Cockroach
The Madagascar hissing cockroach (''Gromphadorhina portentosa''), also known as the hissing cockroach or simply hisser, is one of the largest species of cockroach, reaching at maturity. They are native to the island of Madagascar, which is off the African mainland, where they are commonly found in rotting logs. It is one of some 20 known species of large hissing roaches from Madagascar, many of which are kept as pets, and often confused with one another by pet dealers; in particular, ''G. portentosa'' is commonly confused with '' G. oblongonota'' and '' G. picea''.Delfosse, E. (2004) Les blattes souffleuses de Madagascar. Insectes 153: 19-22. Unlike most cockroaches, they are wingless. They can reproduce asexually, but usually reproduce sexually. They are excellent climbers and can scale smooth glass. Males can be distinguished from females by their thicker, hairier antennae and the very pronounced "horns" on the pronotum. Females carry the ootheca internally, and release the ...

Cockroaches
Cockroaches (or roaches) are a paraphyletic group of insects belonging to Blattodea, containing all members of the group except termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known as pests. The cockroaches are an ancient group, with their ancestors, known as " roachoids", originating during the Carboniferous period, some 320 million years ago. Those early ancestors, however, lacked the internal ovipositors of modern roaches. Cockroaches are somewhat generalized insects lacking special adaptations (such as the sucking mouthparts of aphids and other true bugs); they have chewing mouthparts and are probably among the most primitive of living Neopteran insects. They are common and hardy insects capable of tolerating a wide range of climates, from Arctic cold to tropical heat. Tropical cockroaches are often much larger than temperate species. Modern cockroaches are not considered to be a monophyletic group, as it ha ...

Endemic Fauna Of Madagascar
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ...
