Adetomyrma Aureocuprea
''Adetomyrma aureocuprea'' (from Latin ''aureus'', "golden" and ''cupreus'' "coppery", referring to the body coloration) is a species of ant endemic to Madagascar. Description ''Adetomyrma aureocuprea'', only known from males, is easily separable from the other ''Adetomyrma'' males by the yellowish body color, no mesoscutal notaulus, poorly developed subpetiolar process, lack of posterodorsal projection or lobe on the paramere, short hairs on the compound eye, and vestigial parapsidal line. The males of ''Adetomyrma aureocuprea'' display remarkable morphological variation in, for example, the size of the eye and ocelli, head shape, mesonotal shape, petiolar shape, and hairs on body surface. Sympatry ''A. aureocuprea'' is completely sympatric with '' A. bressleri'', '' A. caputleae'', '' A. goblin'', and '' A. venatrix'', and has been collected within a 20 km radius of '' A. cilium'' and within a 70 km radius of '' A. caudapinniger''. The morphological differences be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

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] |
Insects Described In 2012
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blind Animals
Visual perception in animals plays an important role in the animal kingdom, most importantly for the identification of food sources and avoidance of predators. For this reason, blindness in animals is a unique topic of study. In general, nocturnal or subterranean animals have less interest in the visual world, and depend on other sensory modalities. Visual capacity is a continuum, with humans falling somewhere in the center. Totally blind species * Marsupial moles * '' Sinopoda scurion'' (blind huntsman spider) * Thaumastochelidae (blind deep-sea lobsters) * Blind cave fish * Cave crickets * Texas salamanders * Blind flatworms * '' Tasmanipatus anophthalmus'' (blind velvet worm) * '' Typhloperipatus'' * Eyeless shrimp * Eyeless fish * Cave beetles * Cave crayfish * Some bristletails, isopods and copepods. * ''Martialis heureka'' * Caecilians * Polychelidae * Olm (also known as a Proteus) * Scolecophidia (blind snakes) * Faceless cusk (''Thyphlonus nasus'') * ''Typhlon ...

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 ...

Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of papers f ...

Parapatric
In parapatric speciation, two subpopulations of a species evolve reproductive isolation from one another while continuing to exchange genes. This mode of speciation has three distinguishing characteristics: 1) mating occurs non-randomly, 2) gene flow occurs unequally, and 3) populations exist in either continuous or discontinuous geographic ranges. This distribution pattern may be the result of unequal dispersal, incomplete geographical barriers, or divergent expressions of behavior, among other things. Parapatric speciation predicts that hybrid zones will often exist at the junction between the two populations. In biogeography, the terms parapatric and parapatry are often used to describe the relationship between organisms whose ranges do not significantly overlap but are immediately adjacent to each other; they do not occur together except in a narrow contact zone. Parapatry is a geographical distribution opposed to sympatry (same area) and allopatry or peripatry (two similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adetomyrma Caudapinniger
''Adetomyrma caudapinniger'' (from Latin ''caudapinna'', "tail fin", and ''gero'', "have", referring to the distinctive paramere) is a species of ant endemic to Madagascar. Description ''Adetomyrma caudapinniger'' is only known from males. The male is distinguished easily from other ''Adetomyrma'' males by its bilobed paramere and 2,2 palpal formula. These characters, as well as those observed in the aedeagus An aedeagus (plural aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female. It can be thought of as the insect equivalent of a mammal's penis, though the comparison ..., are unique to ''Adetomyrma caudapinniger'', and a separation of this species from the remaining ''Adetomyrma'' species is clear and consistent. For example, '' A. aureocuprea'', which is superficially similar to ''A. caudapinniger'', has a simple paramere and a 3,3 palpal formula. References * * Amblyoponinae Blind ...

Adetomyrma Cilium
''Adetomyrma cilium'' (from Latin ''cilium'', "eyelash", referring to the long hairs on its compound eye) is a species of ant endemic to Madagascar. Description ''Adetomyrma cilium'' is only known from males. The male of ''A. cilium'' is distinguished easily from the other ''Adetomyrma'' males by a combination of long hairs on the eye, long suberect hairs on the anterior surface of the mesofemur, and a well-developed subpetiolar process. The species is relatively similar to '' A. clarivida'', but differs in the mesofemur hairs and development of the subpetiolar process. Additionally, these species differ in the shape of the aedeagus An aedeagus (plural aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female.

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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
