Callipodida is an order of millipedes containing around 130 species, many characterized by crests or ridges.

Description

Callipodida are long and narrow millipedes, up to Шаблон:Convert in length with 40-60 body segments. A dorsal groove is present running down the mid-line of the body, and many species are ornamented with longitudinal crests or ridges.[1][2] Sexually mature males possess a single pair of gonopods, consisting of the modified anterior leg pair of the 7th body segment, and carried concealed within a pouch.[2][3]

Distribution

Callipodida occurs in North America, Europe, west Asia, southern China and Southeast Asia.[4]

Classification

The living (extant) Callipodida are classified into three suborders, seven families, and approximately 130 species.[5] The genus Sinocallipus, which constitutes the suborder Sinocallipodidea, is thought to be the most primitive, and a sister group to all other callipodans.[6] A fourth, extinct, suborder was described in 2019 to accommodate Burmanopetalum inexpectatum, a 99 million-year-old specimen found in Burmese amber.[7]
