Lophoproctidae
Lophoproctidae is a family of millipedes in the order Polyxenida containing approximately 65 species in 6 genera Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclat .... Description Lophoproctids are distinguished by a soft body, bearing bristles at the posterior end of each diplosegment; they are blind and generally lack pigmentation. Individuals are small, ranging in size from 1.2 to 4.2 mm. Adults have 13 pairs of legs with internal leg buds, except for those in one species (''Lophoturus madecassus''), which have only 11 pairs of legs. Genera As of 2017, the family contains the following genera: '' Alloproctoides'' Marquet & Condé 1950 '' Ancistroxenus'' Schubart 1947 '' Lophoproctinus'' Silvestri 1948 '' Lophoproctus'' Pocock 1894 '' Lophoturus'' Brölemann 1931 '' Plesioproctu ...

Polyxenida
Polyxenida is an order of millipedes readily distinguished by a unique body plan consisting of a soft, non-calcified body ornamented with tufts of bristles – traits that have inspired the common names "bristly millipedes" or "pincushion millipedes". There are at least 86 species in four families worldwide, and are the only living members of the subclass Penicillata. Description Polyxenida differ from other millipedes in having a soft, non-calcified exoskeleton, unique tufts of bristles or setae, fewer legs (no more than 17 pairs), and an absence of copulatory appendages in males. Individuals are small, not exceeding 7 millimeters (0.28 inches). Adults in most species have 13 pairs of legs, but in one species ('' Lophoturus madecassus''), they have only 11 pairs of legs, and in one genus ('' Phryssonotus''), they have 17 pairs of legs, except for one species (''Phryssonotus brevicapensis'') in which they (along with those in one other species, '' Condexenus biramipalpus'') ha ...

Millipede Families
Millipedes, myriapods of the class Diplopoda, contain approximately 12,000 described species organized into 16 extant orders and approximately 140 families. This list is based on Shear, 2011, sorted alphabetically by order and taxonomically within order. Note: The names of millipede orders end in "-ida"; suborders end in "-idea". Superfamilies end in "-oidea", while families end in "-idae".

Filippo Silvestri
Filippo Silvestri (22 June 1873 – 10 June 1949) was an Italian entomologist. He specialised in world Protura, Thysanura, Diplura and Isoptera, but also worked on Hymenoptera, Myriapoda and Italian Diptera. He is also noted for describing and naming the previously unknown order Zoraptera. In 1938 he was nominated to the Pontifical Academy of Sciences, the scientific academy of the Vatican. Silvestri was born in Bevagna. A keen young naturalist, he became assistant to Giovanni Battista Grassi (1854–1925), Director of the Institute of Anatomical Research of the University of Rome. In 1904, Silvestri became Director of the Institute of Entomology and Zoology at the agricultural college in Portici (the Laboratorio di Zoologia Generale e Agraria, now Faculty of Agriculture), a position he held for 45 years. He discovered polyembryony in the 1930s while working on ''Litomatix truncatellus'' Hymenoptera. His collection is in the Museo Civico di Storia Naturale di Genova. Duplica ...

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] |
Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...
