Conotylidae
Conotylidae is a family of millipedes in the order Chordeumatida, containing approximately 19 genera and at least 60 described species. Adult members possess 30 body segments, counting the collum as the first and the telson as the last. The family exhibits its highest diversity in northwestern North America, where five of six subfamilies and ten of fourteen previously described genera occur. Several species are troglobiotic, restricted to cave environments, and some are considered climatic relicts from the Pleistocene.
