Spirobolellidae is a family of millipedes in the order Spirobolida. There are about 11 genera and more than 100 described species in Spirobolellidae. [1] [2] [3]
These 11 genera belong to the family Spirobolellidae:
Chilognatha is a subclass of the class Diplopoda, which includes the vast majority of extant millipede, about 12,000 species.
Glomerida is an order of pill-millipedes found primarily in the Northern Hemisphere. 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.
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, and modified leg pairs on the 8th body ring. Some species had prominent spines while others had a flattened appearance.
Chordeumatida is a large order of millipedes containing some 1200 species with a nearly worldwide distribution. They possess around 30 body segments and reach about 25 mm (0.98 in) in length.
Siphoniulus is a poorly known genus of millipede containing only two living species: S. alba from Indonesia, and S. neotropicus from Mexico and Guatemala. An additional two fossil species are known from Cretaceous amber. Siphoniulus species are the only members of the family Siphoniulidae and order Siphoniulida, making Siphoniulida the smallest millipede order. Few specimens are known, and their classification is contentious, although most recent studies place them as basal members of the Helminthomorpha.
Siphonorhinidae is a family of millipede in the order Siphonophorida. There are at least 4 genera and about 12 described species in Siphonorhinidae.
Siphonophoridae is a family of millipede in the order Siphonophorida. There are about 12 genera and more than 110 described species in Siphonophoridae.
Stemmiulida is an order of millipedes consisting of approximately 130 species, reaching up to 50 mm in length. It contains a single family, Stemmiulidae.
Andrognathidae is a family of millipede in the order Platydesmida. There are about 17 genera and more than 30 described species in Andrognathidae.
Platydesmidae is a family of millipede in the order Platydesmida. There are at least 2 genera and more than 30 described species in Platydesmidae.
Schizopetalidae is a family of crested millipedes in the order Callipodida. There are more than 10 genera in Schizopetalidae.
Brachycybe lecontii is a species of millipede in the family Andrognathidae. It is found in North America.
Cylindroiulus caeruleocinctus is a species of millipede in the family Julidae.
Pachydesmini is a tribe of flat-backed millipedes in the family Xystodesmidae. There are at least 3 genera and more than 20 described species in Pachydesmini.
Chonaphini is a tribe of flat-backed millipedes in the family Xystodesmidae. There are about 6 genera and 19 described species in Chonaphini.
Xystocheirini is a tribe of flat-backed millipedes in the family Xystodesmidae. There are about 5 genera and more than 40 described species in Xystocheirini.
Tynommatidae is a family of millipedes in the order Callipodida. There are about 12 genera and more than 30 described species in Tynommatidae, found mainly in western North America.
Rhachodesmidae is a family of flat-backed millipedes in the order Polydesmida. There are more than 20 genera and at least 80 described species in Rhachodesmidae.
Metopidiotrichidae is a family of millipedes in the order Chordeumatida. There are about 9 genera and at least 70 described species in Metopidiotrichidae.
Iulomorphidae is a family of millipedes in the order Spirostreptida. There are about 11 genera and more than 60 described species in Iulomorphidae.
