Abstract Noteremus summus n. gen., n. sp. occurs at 1100-1300 m on the summit of Mt Weld, southern Tasmania, while its congener N. infimus n. sp. is troglobitic in caves in the Junee-Florentine karst, 30-40 km to the northwest. Like species of Paredrodesmus Mesibov, 2003 and Procophorella Mesibov, 2003, Noteremus spp. have a head + 19 rings, no sphaerotrichomes and pore formula 5, 7-18, and are not assigned to family within the suborder Dalodesmidea. Asphalidesmus golovatchi n. sp. occurs in caves and in forest litter in far southern Tasmania, and the adults have paramedian and median tergal projections. Asphalidesmus Silvestri, 1910 is removed from Polydesmidea, Haplodesmidae and placed in Dalodesmidea without family assignment.
