Millipedes from Australia, 1: Antichiropodini from South Australia (Diplopoda, Polydesmida, Paradoxosomatidae)

Descriptions of two new species: Antichiropus mammillifer n.sp., the first species of the genus recorded from outside Western Australia, related to A. minimus Attems and A. sulcatus Attems, and Tridactylogonus obscurus n.g., n.sp., a small species, taxonomically rather isolated, and perhaps related most closely to Notodesmus scotius Chamberlin, from Tasmania. First record from the Australian continent of Aulacoporus pruvoti (Brölemann), previously known only from New Caledonia. Orthomorpha coarctata (De Saussure), a well-known tropical ubiquist, is recorded for the first time from the Australian continent (Northern Territory).
