Quick Summary

Polyxenus is a genus of millipedes that belongs to the family Polyxenidae. Millipedes in this family are small, with 10 body rings and 13 pairs of legs. They are found worldwide. The term "polyxenid" refers to any millipede within the Polyxenidae family. In terms of reproduction, male millipedes, including those in the genus Polyxenus, transfer sperm to females using threads. They spin thin threads, place sperm drops on them, and use pheromones to attract females. This system helps the sperm attach to the female's genital organs.1234
