Julida is an order of millipedes. Members are mostly small and cylindrical, typically ranging from 10–120 millimetres (0.39–4.72 in) in length.^[1] Eyes may be present or absent, and in mature males of many species, the first pair of legs is modified into hook-like structures.^[2] Additionally, both pairs of legs on the 7th body segment of males are modified into gonopods.^[3]

Distribution

Julida contains predominantly temperate species ranging from North America to Panama, Europe, Asia north of the Himalayas, Asir region, Saudi Arabia, and Southeast Asia.^[4]
