Chordeumatida
Chordeumatida (from the Greek word for "sausage") is a large order of millipedes containing some 1200 species with a nearly worldwide distribution. Also known as "sausage millipedes," they possess around 30 body segments behind the head (including the telson) as adults and reach about in length. Description Chordeumatidans are relatively short-bodied, with only 26 to 32 body segments (including the telson) behind the head. They range in length from . A key feature is the presence of 6 large bristles (setae) on the dorsal surface of each body segment. The first segment ( collum) is relatively narrow, giving the appearance of a distinct "neck" in many species. The body tapers towards the rear, and the rearmost tip (telson) contains silk-producing organs (spinnerets). A dorsal groove runs down the length of the body, and some species possess paranota, lateral extensions of the exoskeleton. Paranota are also found in some other millipedes, notably Polydesmida, from which Chordeumat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Branneria
''Branneria'' is a genus of small millipedes in the order Chordeumatida and the only genus in the family Branneriidae. Individuals reach about long. There are two species known, found in the southeastern USA: ''Branneria bonoculus'' is found in Arkansas and eastern Texas while ''B. carinata'' occurs from North Carolina to Florida and Mississippi. The adult ''B. bonoculus'' millipede has 28 body segments (including the telson), and the adult ''B. carinata'' millipede has 26, both fewer than the 30 usually found in the order Chordeumatida. In both species, the gonopod Gonopods are specialized appendages of various arthropods used in reproduction or egg-laying. In males, they facilitate the transfer of sperm from male to female during mating, and thus are a type of intromittent organ. In crustaceans and millip ... complex in adult males includes three leg pairs (pairs 8 through 10) rather than just the two (pairs 8 and 9) that are usually modified into gonopods in this order.

Chordeumatidae
Chordeumatidae is a family of millipedes belonging to the order Chordeumatida. These millipedes range from 7 mm to 18 mm in length and are found in Europe. Adult millipedes in this family have either 28 (e.g., ''Melagona scutellaris)'' or 30 (e.g., ''M. gallica'', ''Chordeuma proximum'', and ''C. sylvestre'') segments (counting the collum, the telson The telson () is the posterior-most division of the body of an arthropod. Depending on the definition, the telson is either considered to be the final segment of the arthropod body, or an additional division that is not a true segment on accou ..., and the segments in between). This family features distinctive sex-linked modifications to the legs in adults: In the adult female, a legless sternite (the "platosternite") replaces the third pair of legs, and in the adult male, five pairs of legs (pairs 7 through 11) are modified in the gonopod complex. These modifications are more extensive than those found in other adult males in thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buotidae
Buotidae is a family of millipedes belonging to the order Chordeumatida. This family contains a single species, ''Buotus carolinus'', which exhibits sexual dimorphism in segment number: the adult female has 28 segments, but the adult male has only 26, both fewer than the 30 usually found in this order (counting the collum as the first segment and the telson The telson () is the posterior-most division of the body of an arthropod.

Speophilosomatidae
Speophilosomatidae is a family of millipedes belonging to the order Chordeumatida. These millipedes are found in Japan and range from 4 mm to 6 mm in length. Adult millipedes in this family are notable for being among the few in this order with only 26 segments (counting the collum, the telson, and the segments in between) instead of the 30 usually found in chordeumatidans. The adult males in this family are also notable for involving three leg pairs (pairs 7 through 9) in the gonopod Gonopods are specialized appendages of various arthropods used in reproduction or egg-laying.

Millipede
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from the Latin for "thousand feet", no species was known to have 1,000 or more until the discovery of ''Eumillipes persephone'', which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Most millipedes are slow-moving detritivores, eating decaying leaves and other dead plant matter. Some eat fungi or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
