The composition and ecology of the millipede fauna of Victoria remain poorly understood. We collected millipedes as part of a series of ecological arthropod surveys across south-eastern Australia, focusing mainly on Victoria. These samples almost exclusively contained millipedes from the introduced order Julida. We pursued species identification of the julids when it became apparent there were species other than the well-recorded Ommatoiulus moreleti (Lucas, 1860) (Portuguese millipede) in the samples. The majority of specimens were O. moreleti, but we also detected at least one species of Cylindroiulus Verhoeff, 1894, as well as an Ophyiulus Berlese, 1884, species, specimens of which have been identified as Ophyiulus cf. targionii. These are the first Ophyiulus records for Victoria to our knowledge. We present preliminary data on the abundance through the year of Ophyiulus. This is the first study to examine this species in Victoria and little is currently known about its likely impact on agriculture or on native species. Monitoring and research of the species in the future is therefore warranted.

Australia’s mammalian fauna has suffered unparalleled extinctions and declines in recent history. Tasmania has remained largely unaffected by these losses; however, marsupial dynamics are changing rapidly and new threats are emerging. Once abundant throughout south-eastern Australia, the eastern quoll (Dasyurus viverrinus) survives only in Tasmania. Until recently, it was considered widespread and common, but it may be undergoing a rapid and severe decline. The aim of this study was to quantify changes in eastern quoll populations over recent years. Data were compiled from statewide spotlight surveys, repeated historic trapping surveys and bycatch records from non-target trapping surveys. Spotlight surveys from 150 sites across Tasmania revealed a 52% reduction in the number of eastern quoll sightings over the 10 years to 2009. Declines of 61–100% were observed in trapping surveys at three study sites compared with trapping conducted 18–31 years earlier. A reduction in trap success was recorded in five of six non-target surveys, with declines of 51–100% over 1–12 years. These results suggest that the eastern quoll can no longer be presumed secure in Tasmania. Urgent management action may be needed to ensure the future conservation of the species in its last remaining stronghold.
