Approximately 12,000 millipede species have been described. Estimates of the true number of species on earth range from 15,000 [8] to as high as 80,000. [9] Few species of millipede are at all widespread; they have very poor dispersal abilities, depending as they do on terrestrial locomotion and humid habitats.
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, [1] sorted alphabetically by order and taxonomically within order. Note: The names of millipede orders end in "-ida"; suborders end in "-idea".
Polydesmida (from the Greek poly "many" and desmos "bond") is the largest order of millipedes, with more than 5,000 species, [2] [3] including all the millipedes reported to produce hydrogen cyanide (HCN). [4] This order is also the most diverse of the millipede orders in terms of morphology. [5]
MilliBase is an online taxonomic database of all species of class Diplopoda, commonly referred to as millipedes. It is supported by the National Science Foundation, The Field Museum, and LifeWatch Belgium. As of January 2024, 13,626 accepted species are included. [1]
Narceus americanus is a large millipede of eastern North America. Common names include American giant millipede, [1] worm millipede, and iron worm. [2] It inhabits the eastern seaboard of North America west to Georgetown, Texas, north of the Ottine wetlands. [3] It has a nearly cylindrical gray body, reaching a length of 4 inches (100 mm). [4]
Polydesmidae is a family of millipedes in the order Polydesmida. [1] This family includes more than 240 species in about 30 genera. These millipedes have a mostly Holarctic distribution that extends south not only to Mexico and North Africa but also as far as Java. [2]
The City of Angels, a metropolis of freeways and traffic, has a newly discovered species named in its honor: The Los Angeles Thread Millipede. The tiny arthropod was found just underground by ...
Julida is an order of millipedes. Members are mostly small and cylindrical, typically ranging from 10–120 millimetres (0.39–4.72 in) in length. [1] Eyes may be present or absent, and in mature males of many species, the first pair of legs is modified into hook-like structures. [2]
