Metopidiotrichidae
Family of millipedes
Metopidiotrichidae is a family of millipedes in the order Chordeumatida. These millipedes range from 4 mm to 17 mm in length.[1] Adult millipedes in this family have 32 segments (counting the collum as the first segment and the telson as the last), not the 30 segments usually found in this order.[2][1] Adult males in this family (e.g., Reginaterreuma monroei, R. daviesae, R. unicolor, R. major, and Neocambrisoma raveni) often feature a reduced or vestigial leg pair 10 as part of the gonopod complex, in addition to the two leg pairs (pairs 8 and 9) typically modified into gonopods in this order.[3][4] There are about 9 genera and at least 70 described species in Metopidiotrichidae.[5][6][7]
