Pocockia (millipede)
''Pocockia'' is a monotypic genus of millipedes belonging to the family Metopidiotrichidae Metopidiotrichidae is a family of millipedes in the order Chordeumatida. These millipedes range from 4 mm to 17 mm in length. Adult millipedes in this family have 32 segments (counting the collum as the first segment and the telson as the last), ....

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Millipedes
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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metopidiotrichidae
Metopidiotrichidae is a family of millipedes in the order Chordeumatida. These millipedes range from 4 mm to 17 mm in length. Adult millipedes in this family have 32 segments (counting the collum as the first segment and the telson as the last), not the 30 segments usually found in this order. Adult males in this family (e.g., ''Reginaterreuma monroei'', ''R. daviesae'', ''R. unicolor'', ''R. major'', and ''Neocambrisoma raveni'') often feature a reduced or vestigial leg pair 10 as part of the gonopod complex, in addition to the two leg pairs (pairs 8 and 9) typically modified into gonopods in this order. There are about 9 genera and at least 70 described species in Metopidiotrichidae. Genera These nine genera belong to the family Metopidiotrichidae: * ''Australeuma'' Golovatch, 1986 * ''Malayothrix'' Verhoeff, 1929 * ''Metopidiothrix'' Attems, 1907 * ''Neocambrisoma'' Mauriès, 1987 * ''Nesiothrix'' Shear & Mesibov, 1997 * ''Nipponothrix'' Shear & Tanabe, 1994 * ''Pocockia (milli ...
