A study of some Tasmanian Oniscoidea (Crustacea, Isopoda)

The occurrence in Tasmania of seven of the eight species previously recorded is confirmed. It is recognized that Armadillidium vulgare (Latreille) has been recorded under a synonym. Six known species, Styloniscus thomsoni (Chilton), St. phormianus (Chilton), Notoniscus australis (Chilton), Deto marina (Chilton), Actaecia pallida Nicholls & Barnes, and Eluma caelatum (Miers), are recorded from Tasmania for the first time. Additional information on the known species is given. The position of Ligia australiensis Dana is clarified. Chiltonella tasmanica (Chilton) is is transferred to Notoniscus Chilton. Ten new species are established; one of these includes specimens which formerly have been wrongly assigned to Oniscus punctatus Thomson. The position of the following genera; Styloniscus Dana, Notoniscus Chilton, Chiltonella Vandel, Plymophiloscia Wahrberg, Cubaris Brandt, ss after Verhoeff, and Sphaerillo Verhoeff is reviewed.
