Myriapod orders

Scolopendromorpha (from Ancient Greek σκόλοψ (skólops), meaning "thorn", ἔντερον (énteron), meaning "earthworm", and μορφή (morphḗ), meaning "form") is an order of centipedes also known as tropical centipedes or bark centipedes. This order includes about 700 species in five families. These centipedes are found nearly worldwide, with tropical and subtropical regions providing the richest diversity in species. This order includes the only known amphibious centipedes, Scolopendra cataracta, Scolopendra paradoxa, and Scolopendra alcyona.

The Lithobiomorpha (from Ancient Greek λίθος (líthos), meaning "stone", βίος (bíos), meaning "life", and μορφή (morphḗ), meaning "form") also known as stone centipedes, are an order of anamorphic centipedes.

Geophilomorpha is an order of centipedes commonly known as soil centipedes. The name "Geophilomorpha" comes from Ancient Greek γεω- (geo-), meaning "earth", φίλος (phílos), meaning "lover", and μορφή (morphḗ), meaning "form". This group is the most diverse centipede order, with 230 genera. These centipedes are found nearly worldwide but are absent in Antarctica and most Arctic regions.

Scutigeromorpha is an order of centipedes also known as house centipedes. These centipedes are found in the temperate and tropical parts of every continent except Antarctica, with their distribution significantly expanded by the introduction of the Mediterranean species Scutigera coleoptrata throughout Europe, Asia, and North America. The common species S. coleoptrata is a typical representative of this order, lying in wait for other arthropods, then seizing prey using great speed, and all species in this order reflect adaptations for this mode of life.

The Craterostigmomorpha are the least diverse centipede clade, comprising only two extant species, both in the genus Craterostigmus.

Tetramerocerata is an order of pauropods containing 11 families and more than 900 species. This order was created in 1950 to distinguish these pauropods from those in the newly discovered genus Millotauropus, which was found to have such distinctive features as to warrant placement in a separate order (Hexamerocerata) created to contain that genus. The order Tetramerocerata includes the vast majority of pauropod species, as there are only eight species in the order Hexamerocerata, which remains the only other order in the class Pauropoda.
