Malagidris Galokoa
''Malagidris'' is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains six species. Species * ''Malagidris alperti'' Bolton & Fisher, 2014 * '' Malagidris belti'' (Forel, 1895) * '' Malagidris dulcis'' Bolton & Fisher, 2014 * '' Malagidris galokoa'' Bolton & Fisher, 2014 * '' Malagidris jugum'' Bolton & Fisher, 2014 * '' Malagidris sofina'' Bolton & Fisher, 2014 Taxonomy The type species of this genus, ''M. belti'' ( Forel, 1895), has had a moderately varied taxonomic history. It was originally described in the genus ''Aphaenogaster'' ( Mayr, 1853), even though Forel remarked on its 3-segmented antennal club, rather than 4 as is usual in that genus. This character, coupled with the presence of angulate humeri and a queen with a depressed mesosoma, caused Emery (1915) to exclude ''M. belti'' from ''Aphaenogaster'' and transfer it to ''Atopula'' (Emery, 1912). Forel (1917) decided that ''Atopula'' was artificial, "composed of disparate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clypeus (arthropod Anatomy)
The clypeus is one of the sclerites that make up the face of an arthropod. In insects, the clypeus delimits the lower margin of the face, with the labrum articulated along the ventral margin of the clypeus. The mandibles bracket the labrum, but do not touch the clypeus. The dorsal margin of the clypeus is below the antennal sockets. The clypeus is often well-defined by sulci ("grooves") along its lateral and dorsal margins, and is most commonly rectangular or trapezoidal in overall shape. The post-clypeus is a large nose-like structure that lies between the eyes and makes up much of the front of the head in cicadas. In spiders, the clypeus is generally the area between the anterior edge of the carapace A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises.

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...

Homonym
In linguistics, homonyms are words which are homographs (words that share the same spelling, regardless of pronunciation), or homophones (equivocal words, that share the same pronunciation, regardless of spelling), or both. Using this definition, the words ''row'' (propel with oars), ''row'' (a linear arrangement) and ''row'' (an argument) are homonyms because they are homographs (though only the first two are homophones): so are the words ''see'' (vision) and ''sea'' (body of water), because they are homophones (though not homographs). A more restrictive and technical definition requires that homonyms be simultaneously homographs ''and'' homophoneshomonym ''Random House Unabridged Dictionary'' at dictionary.com – that is to say they have identical spelling ''and'' pronunciation, but with different meanings. Examples are the pair ''stalk'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congener (biology)
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carlo Emery
Carlo Emery (25 October 1848, Naples – 11 May 1925) was an Italian entomologist. He is remembered for Emery's rule, which states that insect social parasitism (biology), social parasites are often closely related to their hosts. Early in his career Carlo Emery pursued a course in general medicine, and in 1872 narrowed his interests to ophthalmology. In 1878 he was appointed Professor of Zoology at the University of Cagliari, remaining there for several years until 1881 when he took up an appointment at the University of Bologna as Professor of Zoology, remaining there for thirty-five years until his death. Emery specialised in Hymenoptera, but his early work was on Coleoptera. Prior to 1869, his earliest works were a textbook of general zoology and papers on fishes and molluscs. From 1869 to 1925 he devoted himself almost entirely to the study of ants. Emery published extensively between 1869 and 1926 describing 130 genera and 1057 species mainly in Philogène Auguste Gali ...

Mesosoma
The mesosoma is the middle part of the body, or tagma, of arthropods whose body is composed of three parts, the other two being the prosoma and the metasoma. It bears the legs, and, in the case of winged insects, the wings. In hymenopterans of the suborder Apocrita (wasps, bees and ants), it consists of the three thoracic segments and the first abdominal segment (the propodeum). For historical reasons, in ants it is commonly referred to by the alternative name alitrunk. In scorpions, it is composed of six segments and forms the first part of the abdomen, containing all of the major organs. The first segment contains the sexual organs as well as a pair of vestigial and modified appendages forming a structure called the genital operculum. The second segment bears a pair of featherlike sensory organs known as the pectines; the final four segments each contain a pair of book lungs. The mesosoma is armoured with chitinous plates, on the upper surface by the tergites and on the low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aphaenogaster
''Aphaenogaster'' is a genus of myrmicine ants. About 200 species have been described, including 18 fossil species. They occur worldwide except in South America south of Colombia, sub-Saharan Africa, and Antarctica. They are often confused with '' Pheidole'' or '' Pheidologeton''. These two have major and minor workers, while ''Aphaenogaster'' has only a single worker caste. ''Pheidole'' has three-segmented clubs on its antennae, while ''Aphaenogaster'' has four segments and a larger body size. ''Pheidologeton'' has 11-segmented antennae, while the antennae in ''Aphaenogaster'' are 12-segmented.Genus ''Aphaenogaster'' In Australia, they often build dense, conspicuous nests.Richards, P.J.

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.
