Henri de Saussure and Leo Zehntner described 76 species of millipede in three publications on the fauna of Madagascar (including additions from other islands). These species are listed alphabetically; the holdings of the Muséum
d’histoire naturelle de Genève and the whereabouts of type specimens identifi ed in other institutions are discussed, and the currently valid combination is given for each species. Spirobolus sikorae is transferred to the genus Hylekobolus.
