[2] These millipedes are found in Indochina, Australia, and on Pacific islands from New Zealand to Japan.

The paranota take the form of small bulges or distinct keels.

[4][3] Either the anterior or the posterior gonopods can feature flagella, but never both pairs.

Adult males in this family often feature modifications to the head, antennae, and legs adjacent to the gonopods.

[3] In particular, adult males often feature a reduced or vestigial leg pair 10 as part of the gonopod complex (e.g., Reginaterreuma monroei, R. daviesae, R. unicolor, R. major, and Neocambrisoma raveni), in addition to the two leg pairs (pairs 8 and 9) typically modified into gonopods in this order.
