Chilognatha
Chilognatha is a subclass of the class Diplopoda, which includes the vast majority of extant millipedes, about 12,000 species. Taxonomy The classification of Chilognatha presented below is based on Shear, 2011, and Shear & Edgecombe, 2010 (extinct groups). Recent cladistic and molecular studies have challenged the traditional classification schemes above, and in particular the position of the orders Siphoniulida and Polyzoniida is not yet well established. The placement and positions of extinct groups (†) known only from fossils is tentative and not fully resolved. After each name is listed the author citation: the name of the person who coined the name or defined the group, even if not at the current rank. * Subclass Chilognatha Latrielle, 1802 ** Order †Zosterogrammida Wilson, 2005 (Chilognatha '' incertae sedis'') ** Infraclass Pentazonia Brandt, 1833 *** Order † Amynilyspedida Hoffman, 1969 *** Superorder Limacomorpha Pocock, 1894 **** Order Glomeridesmida Co ...

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

Pentazonia
Pentazonia is a taxonomic infraclass of millipedes containing the pill-millipedes (Oniscomorpha) which can roll into a ball and the order Glomeridesmida which cannot. Defining traits ( apomorphies) include divided sternites, a labrum with single median tooth, and an enlarged pygidium on the hind-most body segment. Pentazonia is in the dominant millipede subclass Chilognatha Chilognatha is a subclass of the class Diplopoda, which includes the vast majority of extant millipedes, about 12,000 species.

In contrast to the Helminthomorpha – the other Chilognathan infraclass, the sperm-transferring legs are located on posterior body segments and known as ''telopods''.

Zosterogrammida
Zosterogrammidae is an extinct family of millipedes containing three genera, each with a single species. Fossils are known from the Czech Republic, Scotland, and the USA. Zosterogrammidae constitutes the sole family of the order Zosterogrammida. Description Zosterogrammids have broad heads, 20 to 32 body segments, with a body tapering towards the head and rear. The dorsal plates of each segment are very broad and the rear portion of each is segment ornamented with lines. Size ranges from to in length. Superficially they are similar to the living Polyzoniida in body proportion. Taxonomy and distribution Zosterogrammidae is placed in its own order, Zosterogrammida. Zosterogrammida is considered '' incertae sedis'' (uncertain placement) within the millipede subclass Chilognatha. :Family †Zosterogrammidae Wilson, 2005 :: ''Casiogrammus ichthyeros'' Wilson, 2005 - Lanarkshire, Scotland; Wenlock (Silurian) :: ''Purkynia lata'' Fritsch, 1899 - Nýřany, Czech Republic; ...

Pleurojulida
Pleurojulidae is an extinct family of millipedes known from the Westphalian (stage), Westphalian stage of the upper Carboniferous that are distinct enough to be placed in their own order, Pleurojulida. Fossil pleurojulids up to 10 centimeters long are known from Europe and the United States.

Euphoberiida
Euphoberiidae is an extinct family of archipolypodan millipedes known from the Upper Pennsylvanian of Europe and North America. The family includes relatively large millipedes measuring up to long bearing distinctive spines and were the dominant millipedes of the Pennsylvanian.Shear, William A.

Chapman & Hall, London, pp. 211–219 Description Euphoberiids are characterized by sets of outward-pointing spines on each diplosegment (body ring), one pair extending laterally (to the sides), the other pair higher on the body. At the base of each lateral spine is an ozopore An ozopore is the opening of a defensive gland present in some arthropods, notably in millipedes of the order Polydesmida [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subclass (biology)
In biological classification, class ( la, classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order. History The class as a distinct rank of biological classification having its own distinctive name (and not just called a ''top-level genus'' ''(genus summum)'') was first introduced by the French botanist Joseph Pitton de Tournefort in his classification of plants that appeared in his ''Eléments de botanique'', 1694. Insofar as a general definition of a class is available, it has historically been conceived as embracing taxa that combine a distinct ''grade'' of organization—i.e. a 'level of complexity', measured in terms of how differentiated their organ systems are into distinct regions or sub-organs—with a distinct ''type'' of construction, ...

Archipolypoda
Archipolypoda is an extinct group of millipedes known from fossils in Europe and North America and containing the earliest known land animals. The Archipolypoda was erected by Scudder (1882) but redefined in 2005 with the description of several new species from Scotland. Distinguishing characteristics include relatively large eyes with densely packed ocelli (sometimes interpreted as compound eyes), and modified leg pairs on the 8th body ring. Some species had prominent spines while others had a flattened appearance. Classification The Archipolypoda as currently recognized consists of four orders, many with monotypic families and genera, as well as five species of uncertain placement (''incertae sedis'').
