Kylindotherium is a monotypic genus of giant Pill millipede, native to South Africa. It was first described in 1926 by Attems. [1] [2] It consists of a single species, Kylindotherium leve.
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 Latin for "thousand feet", no species was known to have 1,000 or more until the discovery in 2020 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.
Pill millipedes are any members of two living orders of millipedes, often grouped together into a single superorder, Oniscomorpha. The name Oniscomorpha refers to the millipedes' resemblance to certain woodlice (Oniscidea), also called pillbugs or "roly-polies". However, millipedes and woodlice are not closely related ; rather, this is a case of convergent evolution.
Sphaerotheriidae is a family of giant pill millipedes of the class Diplopoda. Millipedes of this family are distributed in southern Africa.
Procyliosoma is a genus of pill millipede found in Australia and New Zealand. Formerly classified in the family Sphaerotheriidae, in 2009 Procyliosoma was reclassified as the only genus in the family Procyliosomatidae.
Glomerida is an order of pill-millipedes found primarily in the Northern Hemisphere. Also known as northern pill millipedes, they superficially resemble pill-bugs or woodlice, and can enroll into a protective ball. They have twelve body segments, 17 to 19 pairs of legs, and males have enlarged rear legs involved in mating. The order includes about 30 genera and at least 280 species, including Glomeris marginata, the common European pill-millipede. The order contains members in Europe, South-east Asia and the Americas from California to Guatemala. Although historically considered closely related with the similar sphaerotheriidans that also enroll, some DNA evidence suggest they may be more closely related to glomeridesmidans, a poorly known order that does not enroll.
Sphaerotheriida is an order of millipedes in the infraclass Pentazonia, sometimes known as giant pill millipedes. They inhabit Southern Africa, Madagascar, South and Southeast Asia, Australia and New Zealand. Like the Northern Hemisphere pill millipedes of the order Glomerida, these millipedes can roll into a ball when disturbed. When they are rolled-up, most sphaerotheriidans reach a maximum size of a cherry or golf ball, but some species from Madagascar can even reach the size of an orange. When rolled-up, predators are unable to unravel giant pill millipedes since the margins of their second and last dorsal plates fit perfectly into one another, creating a sealed ball. A few giant pill millipede species are able to produce sound, the only millipedes known to do this. This order of millipedes is also unique in that some African species are used for medicinal purposes.
Calostreptus is a genus of giant African millipedes in family Spirostreptidae, containing three species:
Anastreptus is a genus of giant African millipedes in family Spirostreptidae, containing four species:
Sphaeromimus, or the chirping giant pill millipedes, is a genus of giant pill millipedes endemic to southeastern Madagascar. Though described in 1902, the genus was up to 2005 known from a single male specimen, whose appearance was so unusual that the authors suspected a mislabeled giant pill-millipede from India. Their unusual and distinct morphology includes well-developed stridulation organs, probably as devices for courtship. These are the male ‘harp’ and the female ‘washboard’, which contain more stridulation ribs than in other members of the order Sphaerotheriida. They have a closer affinity with the Indian genus Arthrosphaera than to other Malagasy genera, though all belong to the Arthrosphaeridae.
Mardonius is a genus of giant African millipedes in family Spirostreptidae, containing nine species:
Triaenostreptus is a genus of giant African millipedes in family Spirostreptidae, containing eight species:
Telodeinopus is a genus of giant African millipedes in family Spirostreptidae, containing the following species:
Zephroniidae is a family of giant pill millipedes in the taxonomic order Sphaerotheriida. They occur in southeast Asia from the Himalayas and China south and east to Sulawesi and to Australia, and also inhabit some Philippine islands.
Chordeumatida is a large order of millipedes containing some 1200 species with a nearly worldwide distribution. Also known as sausage millipedes, they grow and develop through a series of moults, adding segments until they reach a fixed number in the adult stage, which is usually the same for a given sex in a given species, at which point the moulting and the addition of segments and legs stop. This mode of development, known as teloanamorphosis, distinguishes this order from most other orders of millipedes, which usually continue to moult as adults, developing through either euanamorphosis or hemianamorphosis.
Zephronia is a genus of giant pill millipedes in the family Zephroniidae. This genus includes 47 species distributed throughout N. India, Myanmar, Thailand, Malayan Peninsula, Java, Sumatra and Borneo.
Chryseobacterium arthrosphaerae is a Gram-negative and rod-shaped bacteria from the genus Chryseobacterium which has been isolated from the faeces of the pill millipede Arthrosphaera magna in India.
Microbacterium arthrosphaerae is a Gram-positive and rod-shaped bacterium from the genus Microbacterium which has been isolated from the pill millipede Arthrosphaera magna in India.
Zoosphaerium darthvaderi, also known as the Darth Vader giant pill millipede, is a species of giant pill millipede endemic to the island state of Madagascar. It is named after the Star Wars character Darth Vader. The millipede is restricted to the Ambohitantely Reserve and is considered an extremely endangered species.
Zoosphaerium is a genus of giant pill millipedes endemic to Madagascar. Some species within this genus express island gigantism. The largest of the known species of giant pill millipede known is Zoosphaerium neptunus, which is capable of growing to lengths of 90 mm.
Glomeris punica, is a species of pill millipede belonging to the genus Glomeris and the family Glomeridae.
