Phryssonotus novaehollandiae Silvestri, 1923 : the sole Australian representative of the millipede Family Synxenidae

Examination of synxenid millipedes from a number of collections confirms that Phryssonotus novaehollandiae is the sole representative of the genus and family in Australia. P. novaehollandiae was found to have the most widespread distribution of any native Australian millipede species. It occurs in a range of well-drained habitats including heathlands, woodlands and coastal scrub. Several thelytokous (female only) populations were found in coastal areas of south eastern Australia.
