Spirobolida is an order of "round-backed" millipedes containing approximately 500 species in 12 families.[1] Its members are distinguished by the presence of a "pronounced suture that runs "vertically down the front of the head".[2] Most of the species live in the tropics, and many are brightly coloured.[2] Mature males have two pairs of modified legs, the gonopods, consisting of the 8th and 9th leg pair: the posterior gonopods are used in sperm-transfer while the anterior gonopods are fused into a single plate-like structure.[3]
