Deharvengius
''Deharvengius'' is a monotypic genus of flat-backed millipede in the family Trichopolydesmidae, and ''Deharvengius bedosae'' is the only species in this genus. This millipede is notable as one of the very few species in the order Polydesmida to feature adults with only 18 segments (counting the collum as the first segment and the telson as the last) rather than the 20 segments usually found in this order. This species is found in Vietnam. Discovery This genus and its type species were first described in 2014 by the biologists Sergei Golovatch, Jean-Jacques Geoffroy, and Didier VandenSpiegel. They based the original description of this genus and its only species on a male holotype and twelve paratypes (three males, four females, and five juveniles). This genus and this species are named in honor of the biologists Louis Deharveng and Anne Bedos of the Muséum National d’Histoire Naturelle in Paris. Deharveng and Bedos extracted the type specimens from soil collected in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichopolydesmidae
Trichopolydesmidae is a family of millipedes in the order Polydesmida. Some authorities deem this family to include Fuhrmannodesmidae, Mastigonodesmidae, Macrosternodesmidae, and Nearctodesmidae as junior synonyms. Others adopt narrower definitions of this family, for example, including only Fuhrmannodesmidae and Mastigonodesmidae as synonyms. Under the broader definition, this family includes about 140 species distributed among about 75 genera. These species are found mainly in the Northern Hemisphere, especially in the tropics but also in temperate regions. About 80 species and 55 genera are tropical, whereas about 60 species and 20 genera are Holarctic. Description Millipedes in this family (broadly defined) are small, ranging from 2 mm to 20 mm in length. These millipedes have 18, 19, or 20 segments, counting the collum as the first segment and the telson as the last. This family includes two genera ('' Galliocookia'' and '' Occitanocookia'') notable for featuring sexua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polydesmida
Polydesmida (from the Greek ''poly'' "many" and ''desmos'' "bond") is the largest order of millipedes, with more than 5,000 species, including all the millipedes reported to produce hydrogen cyanide (HCN). This order is also the most diverse of the millipede orders in terms of morphology. Millipedes in this order are found in all regions of the world other than Antarctica. Description Members of the order Polydesmida are also known as flat-backed millipedes, because on most species, each body segment has wide lateral keels known as paranota. These keels are produced by the posterior half (metazonite) of each body ring behind the collum. Polydesmids have no eyes, and vary in length from 1.4 to 134 mm. Many of the larger species show bright coloration patterns which warn predators of their toxic secretions. Adults usually have 20 segments, counting the collum as the first ring and the telson as the last ring. Juveniles have from 7 to 19 rings. In species with the usual 20 seg ...

National Museum Of Natural History, France
The French National Museum of Natural History ( ; abbr. MNHN) is the national natural history museum of France and a of higher education part of Sorbonne University. The main museum, with four galleries, is located in Paris, France, within the Jardin des Plantes on the left bank of the River Seine. It was formally founded in 1793, during the French Revolution, but was begun even earlier in 1635 as the royal garden of medicinal plants. The museum now has 14 sites throughout France. Since the 2014 reform, it has been headed by a chairman, assisted by deputy managing directors. The Museum has a staff of approximately 2,350 members, including six hundred researchers. It is a member of the national network of naturalist collections (RECOLNAT).

Seta
In biology, setae (; seta ; ) are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Depending partly on their form and function, protostome setae may be called macrotrichia, chaetae, Scale (insect anatomy), scales, or Common name, informally, hairs. The setal membrane is not Cuticle, cuticularized, so movement is possible. Annelid setae are stiff bristles present on the body. They allow earthworms and their relatives to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (the group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. The setae on polychaete worms are referred to as chaeta due to their differing morphology. Crustaceans have mechano- and chemos ...

Tergum
A ''tergum'' (Latin for "the back"; : ''terga'', associated adjective tergal) is the dorsal ('upper') portion of an arthropod Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metam ... segment other than the head. The anterior edge is called the 'base' and posterior edge is called the 'apex' or 'margin'. A given tergum may be divided into hardened plates or sclerites commonly referred to as tergites. In a thoracic segment, for example, the tergum may be divided into an anterior notum and a posterior scutellum. Lateral extensions of a tergite are known as paranota (Greek for "alongside the back") or ''carinae'' (Latin for "keel"), exemplified by the flat-backed millipedes of the order Polydesmida. Kinorhynchs have tergal and sternal plates too, though seemingly not homologous with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antenna (zoology)
An antenna (plural: antennae) is one of a pair of appendages used for Sensory system, sensing in arthropods. Antennae are sometimes referred to as ''feelers''. Antennae are connected to the first one or two Segmentation (biology), segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing tactition, touch, air motion, heat, vibration (sound), and especially insect olfaction, smell or gustation, taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate (biology), substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
