Tetramorium Smaug
''Tetramorium smaug'' is a species of myrmicine ant native to Ambatovy, Amber Mountain National Park, and Ivohibe in Madagascar. It was found in montane rainforests around elevations of . It is believed to live in vegetation as opposed to on the forest floor. Coloration is dark brown or black. The head and mesosoma have rough surfaces while the gaster is smooth. The head has a large number of hairs, but the amount of hair decreases on each segment posteriorly. The species has long propodeal spines with a broad base. It was named after the dragon Smaug from J. R. R. Tolkien's novel ''The Hobbit''.

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] |
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] |

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 ...

The Hobbit
''The Hobbit, or There and Back Again'' is a children's fantasy novel by English author J. R. R. Tolkien. It was published in 1937 to wide critical acclaim, being nominated for the Carnegie Medal and awarded a prize from the '' New York Herald Tribune'' for best juvenile fiction. The book remains popular and is recognized as a classic in children's literature. ''The Hobbit'' is set within Tolkien's fictional universe and follows the quest of home-loving Bilbo Baggins, the titular hobbit, to win a share of the treasure guarded by a dragon named Smaug. Bilbo's journey takes him from his light-hearted, rural surroundings into more sinister territory. The story is told in the form of an episodic quest, and most chapters introduce a specific creature or type of creature of Tolkien's geography. Bilbo gains a new level of maturity, competence, and wisdom by accepting the disreputable, romantic, fey, and adventurous sides of his nature and applying his wits and common s ...

Smaug
Smaug () is a dragon and the main antagonist in J. R. R. Tolkien's 1937 novel ''The Hobbit'', his treasure and the mountain he lives in being the goal of the quest. Powerful and fearsome, he invaded the Dwarf kingdom of Erebor 150 years prior to the events described in the novel. A group of thirteen dwarves mounted a quest to take the kingdom back, aided by the wizard Gandalf and the hobbit Bilbo Baggins. In ''The Hobbit'', Thorin describes Smaug as "a most specially greedy, strong and wicked worm". Critics have identified close parallels with what they presume are sources of Tolkien's inspiration, including the dragon in ''Beowulf'', who is provoked by the stealing of a precious cup, and the speaking dragon Fafnir, who proposes a betrayal to Sigurd. A further source may be Henry Wadsworth Longfellow's 1855 poem ''The Song of Hiawatha'', where Megissogwon, the spirit of wealth, is protected by an armoured shirt, but whose one weak spot is revealed by a talking bird.

Dragon
A dragon is a reptilian legendary creature that appears in the folklore of many cultures worldwide. Beliefs about dragons vary considerably through regions, but dragons in western cultures since the High Middle Ages have often been depicted as winged, horned, and capable of breathing fire. Dragons in eastern cultures are usually depicted as wingless, four-legged, serpentine creatures with above-average intelligence. Commonalities between dragons' traits are often a hybridization of feline, reptilian and avian features. Scholars believe huge extinct or migrating crocodiles bear the closest resemblance, especially when encountered in forested or swampy areas, and are most likely the template of modern Oriental dragon imagery. Etymology The word ''dragon'' entered the English language in the early 13th century from Old French ''dragon'', which in turn comes from la, draconem (nominative ) meaning "huge serpent, dragon", from Ancient Greek , (genitive , ) "serpent, giant s ...

Propodeum
The propodeum or propodium is the first abdominal segment in Apocrita Hymenoptera (wasps, bees and ants). It is fused with the thorax to form the mesosoma. It is a single large sclerite, not subdivided, and bears a pair of spiracles. It is strongly constricted posteriorly to form the articulation of the petiole, and gives apocritans their distinctive shape. There may be a suture between the propodeum and the thorax, like in Symphyta Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay ... or not, and the presence or absence of such suture can aid in identifying specimens. In molluscs Propodium is the anterior (frontal) part of the foot of a mollusk. References Insect anatomy Gastropod anatomy {{insect-anatomy-stub ...

Gaster (insect Anatomy)
The gaster is the bulbous posterior portion of the metasoma found in hymenopterans of the suborder Apocrita ( bees, wasps and ants). This begins with abdominal segment III on most ants, but some make a constricted postpetiole out of segment III, in which case the gaster begins with abdominal segment IV. Certain ants in the genus '' Cataglyphis'', specifically ''Cataglyphis bicolor'' and ''Cataglyphis fortis'', have a cubiform petiole that allows them to decrease their inertia Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law ... (and therefore increase their speed) by raising their gaster into an upright position. References Insect anatomy {{insect-anatomy-stub de:Gaster ...

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 ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system.
