Adetomyrma Venatrix
''Adetomyrma venatrix'', more commonly known as the Dracula ant, so named because of its grisly feeding habits of drinking the blood of its young, is an endangered species of ants endemic to Madagascar. Workers of this species are blind. The species was described as the type species of '' Adetomyrma'' in 1994, with the genus being an atypical member of its tribe. Description ''Adetomyrma venatrix'' was described on the basis of specimens belonging to the worker caste collected from Zombitse Forest, in western Madagascar. The key characteristics of the species was the absence of a clear petiole when viewed from above due to the third abdominal tergite (the sclerite on the dorsal side) lacking a differentiated pretergite. The gaster is large and without constrictions. The ant is blind and has a long sting. It was placed with reservations in the tribe Amblyoponini as it lacks the typical characters of the group. Later studies considered them as being close to the ancestral members ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adetomyrma
''Adetomyrma'' is a genus of ants endemic to Madagascar. Workers of this genus are blind. The type species '' Adetomyrma venatrix'' was described in 1994, with the genus being an atypical member of its tribe, the Amblyoponini. This tribe includes the Dracula ants, members of which can feed on the hemolymph of larvae and pupae. Taxonomy ''Adetomyrma'' was first described as a Malagasy endemic monotypic genus by Ward in 1994. Ward (1994) assigned this genus to Amblyoponini within the subfamily Ponerinae on the basis of the worker morphology of the type species ''Adetomyrma venatrix''. Later, Bolton (2003) raised this tribe to subfamily status as Amblyoponinae Amblyoponinae is a subfamily of ants in the poneromorph subfamilies group containing 13 extant genera and one extinct genus.

Later, Bolton (2003) raised this tribe to subfamily status as Amblyoponinae. Biology The colonies, the first of which was found in a rotting log, may contain as many as 10,000 workers, winged males and several wingless queens (the majority of ant species feature winged queens). The workers use venom to stun their prey which are brought back to the colony for the larvae to feed upon. The colour of th ...

Philip S
Philip, also Phillip, is a male given name, derived from the Greek (''Philippos'', lit. "horse-loving" or "fond of horses"), from a compound of (''philos'', "dear", "loved", "loving") and (''hippos'', "horse"). Prominent Philips who popularized the name include kings of Macedonia and one of the apostles of early Christianity. ''Philip'' has many alternative spellings. One derivation often used as a surname is Phillips. It was also found during ancient Greek times with two Ps as Philippides and Philippos. It has many diminutive (or even hypocoristic) forms including Phil, Philly, Lip, Pip, Pep or Peps. There are also feminine forms such as Philippine and Philippa.

Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic (ecology)
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Madagascar (the 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 its wildlife is endemic. Human settlement of Madagascar occurred during or before the mid first millennium AD by Austronesian peoples, presumably arriving on outrigger cano ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal (phylogenetics)
In phylogenetics, basal is the direction of the ''base'' (or root) of a rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a 'key innovation' implies some degree of correlation between evolutionary innovation and diversification. However, such a correlation does not make a given case predicable, so ancestral characters should not be imputed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amblyoponinae
Amblyoponinae is a subfamily of ants in the poneromorph subfamilies group containing 13 extant genera and one extinct genus. The ants in this subfamily are mostly specialized subterranean predators. Adult workers pierce the integument (non lethally) of their larvae and pupa to imbibe haemolymph, earning them the common name Dracula ant. Identification Amblyoponinae is characterized by these worker characters: eyes small or absent, situated behind midlength of side of head; anterior margin of clypeus with specialized dentiform setae; promesonotal suture flexible; petiole very broadly attached to abdominal segment 3 and without a distinct posterior face; postpetiole absent; sting present and well developed. Systematics The subfamily was formerly considered a tribe within Ponerinae, but was elevated to its own subfamily in 2003 when Barry Bolton divided Ponerinae into six subfamilies. *Amblyoponinae Forel, 1893 ** Amblyoponini Forel, 1893 *** '' Adetomyrma'' Ward, 1994 *** ''Ambl ...

Amblyopone Pluto
''Stigmatomma pluto'' is a species of ant in the subfamily Amblyoponinae. The species was first described as ''Amblyopone pluto'' by Gotwald and Levieux in 1972 and moved to the genus '' Stigmatomma'' in 2012. ''Stigmatomma pluto'' is endemic to the unburned savanna A savanna or savannah is a mixed woodland- grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to ...s of central Ivory Coast.
