Dermapteron incerta is an extinct species of earwig in the family Protodiplatyidae. [1] It is the only species in the genus Dermapteron. [1]
Genus is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Extinction is the termination of a taxon by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" after a period of apparent absence.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
Earwigs make up the insect order Dermaptera. With about 2,000 species in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps-like pincers on their abdomen, and membranous wings folded underneath short, rarely used forewings, hence the scientific order name, "skin wings". Some groups are tiny parasites on mammals and lack the typical pincers. Earwigs are found on all continents except Antarctica.
Endemism is the state of a species only 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 also be referred to as an endemism or, in scientific literature, as an endemite. Similarly many species found in the Western ghats of India are examples of endemism.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
The Saint Helena earwig or Saint Helena giant earwig is an extinct species of very large earwig endemic to the oceanic island of Saint Helena in the south Atlantic Ocean.
A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour, or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet. For example, Boa constrictor is one of the species of the genus Boa, with constrictor being the species' epithet.
Archidermaptera is an extinct suborder of earwigs in the order Dermaptera. It is one of two extinct suborders of earwigs, and contains two families known only from Late Triassic to Early Cretaceous fossils. The suborder is classified on the basis of general similarities. The Archidermaptera share with modern earwigs tegmenized forewings, though they lack the distinctive forceps-like cerci of modern earwigs, have external ovipositors, and possess ocelli. The grouping has been suggested to be paraphyletic.
Protodiplatyidae is an extinct family of earwigs. It is one of three families in the suborder Archidermaptera, alongside Dermapteridae and Turanovia. Species are known from Jurassic and Early Cretaceous fossils and have unsegmented cerci and tarsi with four to five segments.
Microdiplatys is an extinct genus of earwigs, in the family Protodiplatyidae. It is one of only six genera in the family, its family being the only one in the suborder.
Protodiplatys is an extinct genus of earwigs, in the family Protodiplatyidae, the suborder Archidermaptera, and the order Dermaptera. It is known from three species, P. fortis and P. gracilis, which are known from the Middle-Late Jurassic Karabastau Formation in Kazakhstan, and P. mongoliensis from the Aptian aged Gurvan-Eren Formation of Mongolia.
Archidermapteron martynovi is an extinct species of earwig, in the genus Archidermapteron, family Protodiplatyidae, the suborder Archidermaptera, the order Dermaptera, and is the only species in the genus Archidermapteron, which simply means "ancient member of the Dermaptera". It had long, segmented cerci unlike modern species of Dermaptera, but tegmina and hind wings that folded up into a "wing package" that are like modern earwigs. The only clear fossil of the species was found in Russia.
Asiodiplatys is a monotypic genus containing the single species Asiodiplatys speciousus, an extinct species of earwig in the family Protodiplatyidae. It had long and thin cerci that were very different from modern species of Dermaptera, but tegmina and hind wings that folded up into a "wing package" that are like modern earwigs. Like Archidermapteron martynovi, the only clear fossil of the species was found in Russia.
Microdiplatys campodeiformis is an extinct species of earwig in the family Protodiplatyidae. It is one of only two species in the genus Microdiplatys, the other being Microdiplatys oculatus.
Microdiplatys oculatus is an extinct species of earwig in the family Protodiplatyidae. It is one of only two species in the genus Microdiplatys, the other being Microdiplatys campodeiformis.
Turanovia incompleta is an extinct species of archidermapteran earwig. It is the only species in the genus Turanovia and family Turanoviidae. It is found in the Middle-Late Jurassic (Callovian-Oxfordian) Karabastau Formation of Kazakhstan.
Neodermaptera, sometimes called Catadermaptera, is a suborder of earwigs in the order Dermaptera. There are more than 2,000 described species in Neodermaptera.
Dermapteridae is an extinct family of earwigs known from the Late Triassic to Mid Cretaceous, it is part of the extinct suborder Archidermaptera, alongside Protodiplatyidae and Turanovia. It was first named as a subfamily by Vishniakova in 1980, and elevated to family status by Engel in 2003 without discussion.
Eodermaptera is an extinct suborder of earwigs known from the Middle Jurassic to Mid Cretaceous. Defining characteristics include "tarsi three-segmented, tegmina retain venation, 8th and 9th abdominal tergite in females are narrowed, but separate from 10th tergite and not covered by 7th tergite and exposed ovipositor" They are considered to be more closely related to Neodermaptera than the more basal Archidermaptera.
