Haplodesmidae

Haplodesmidae is a family of millipedes in the order Polydesmida. Species occur in East Asia, Southeast Asia, and Oceania, although some species have been introduced to the New world tropics. Species are small bodied (generally less than 10 mm), often with elaborate sculpturing on the tergites (dorsal portion of exoskeleton), and some species are capable of rolling into a near-complete ball.
