ZooKeys 754: 103–111. https://doi.org/10.3897/zookeys.754.25704 Abstract Lissodesmus nivalis sp. n. is described from 1450–1550 m elevation on the treeless, alpine Ben Lomond plateau in northeast Tasmania, Australia. The new species is distinguished from all other Tasmanian and Victorian Lissodesmus species by a unique combination of gonopod telopodite features: solenomere without a pre-apical process, tibiotarsus Y-shaped, femoral process L-shaped with forked tips, prefemoral process with a long comb of teeth below an irregularly dentate apical margin, and a roughened “shoulder process” near the base of the prefemoral process. Keywords Diplopoda, Polydesmida, Dalodesmidae, Tasmania, Australia Introduction Several species of the millipede family Dalodesmidae can be found in treeless alpine areas of Tasmania, among them Dasystigma margaretae (Jeekel, 1984), which was collected on an alpine “cushion plant” at 1150 m at the type locality on Tasmania’s Central Plateau (Mesibov 2003).
