Chilognatha Explained

Chilognatha is a subclass of the class Diplopoda, which includes the vast majority of extant millipedes, about 12,000 species.

Taxonomy

The classification of Chilognatha presented below is based on Shear, 2011,^[1] and Shear & Edgecombe, 2010 (extinct groups). Recent cladistic and molecular studies have challenged the traditional classification schemes above, and in particular the position of the orders Siphoniulida and Polyzoniida is not yet well established.^[2] The placement and positions of extinct groups (†) known only from fossils is tentative and not fully resolved.^[3] After each name is listed the author citation: the name of the person who coined the name or defined the group, even if not at the current rank.
