Suborders

The Geophilomorpha, commonly known as soil centipedes, [1] are epimorphic [2] and bear upwards of 27 leg-bearing segments. They are eyeless and blind, and bear spiracles on all leg-bearing segments—in contrast to other groups, which usually bear them only on their 3rd, 5th, 8th, 10th, 12th, and 14th segments—a "mid-body break", accompanied by a change in tagmatic shape, occurring roughly at the interchange from odd to even segments. This group is the most diverse centipede order, with 230 genera. [3] Centipedes in this order each have an odd number of leg-bearing segments ranging from 27 (in the genus Schendylops) [4] to 191 (in the species Gonibregmatus plurimipes). [2] They also have 14–segmented antennae. This order is a monophyletic group including two suborders: the monophyletic Placodesmata, which contains Mecistocephalidae, and Adesmata, which includes the superfamilies Himantarioidea ( Oryidae, Himantariidae, and Schendylidae, including Ballophilidae) and Geophiloidea ( Zelanophilidae, Gonibregmatidae including Eriphantidae and Neogeophilidae, and Geophilidae including Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, [5] and Macronicophilidae). [6] Segment number is usually fixed by species in the family Mecistocephalidae, unlike the case in other families in this order, in which the segment number usually varies within each species. [7] The name "Geophilomorpha" is from Ancient Greek roots meaning "formed to love the earth." [8]
