Adetomyrma Cassis
''Adetomyrma cassis'' (from Latin ''cassis'', "helm", referring to the shape of its genital capsule) is a species of ant endemic to Madagascar. Description ''Adetomyrma cassis'' is only known from a single male collected in the Ambatovaky Reserve, Madagascar. The male of ''A. cassis'' is distinguished easily from other ''Adetomyrma'' males by a distinct and flatted projection on the posterior portion of the paramere Parameres ('side parts') are part of the external reproductive organs of male insects and the term was first used by Karl Wilhelm Verhoeff, Verhoeff in 1893 for the lateral genital lobes in Coleoptera. The primary phallic lobes which appear in th .... This projection is not separated from the paramere by a deep notch as in '' A. bressleri''. This genital character observed in ''Adetomyrma cassis'' is completely unique and sufficient to regard this male as a distinct species.

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 ...

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] |
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 ...

Ambatovaky Reserve
Ambatovaky Special Reserve is a tropical rainforest and wildlife reserve in the north-east of Madagascar (). It is designated by Bird Life International as an Important Bird Area for the large number of endemic species of birds. Geography This remote reserve ranges from the north-east coast of Madagascar to the Analamerana karstic plateau with elevations to in the Soanierana Ivongo District, Analanjirofo region. It is between the Marimbona river, which forms the southern border, and Simianona river which forms the northern border. The reserve headquarters are in Soanierana Ivongo and the park is only accessible by canoe along the Marimbona River. Flora and fauna The reserve is mainly covered by dense deciduous dry forest and is the last place for the critically endangered lemur, Perrier's sifaka (''Propithecus perrieri''). There are five other species of lemurs found on the reserve. Four have been given the conservation status of endangered by the International Union for Con ...

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. The ants in this subfamily are mostly specialized subterranean predators. Adult workers pierce the integument (non letha ....

Paramere
Parameres ('side parts') are part of the external reproductive organs of male insects and the term was first used by Karl Wilhelm Verhoeff, Verhoeff in 1893 for the lateral genital lobes in Coleoptera. The primary phallic lobes which appear in the nymph or larval stages may become a pair of penes in the Ephemeroptera or a simple median penis in the Thysanura. In higher insect orders from Orthoptera to Hymenoptera, each of the primary lobes is divided into two secondary lobes or phallomeres, termed parameres and mesomeres (NB: this use of the term "mesomere" is not to be confused with the Somite, same term in Segmentation (biology), segmentation embryology.) In adult insects parameres may elongate and become genital claspers. These claspers may themselves occur in two segments, forming a Anatomical terms of location#Proximal and distal, proximal basimere and a Anatomical terms of location#Proximal and distal, distal telomere (insect morphology), telomere or harpago ('grappling hook' ...

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 ...

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 ...

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 ...

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] |
Hymenoptera Of Africa
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
