Julida is an order of millipedes. Members are long 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[edit]

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

Classification[edit]

The order Julida contains approximately 750 species, divided into the following superfamilies and families:[5]

Blaniuloidea C. L. Koch, 1847
Juloidea Leach, 1814
Nemasomatoidea Bollman, 1893
Paeromopodoidea Cook, 1895
Parajuloidea Bollman, 1893
