A new chiridotid genus is erected: Archedota O’Loughlin gen. nov. In addition, seven apodid species, new to science, are described (O’Loughlin as author) for the rocky shallows, continental shelf and continental slope of southern Australia: chiridotids Archedota lapidea, Taeniogyrus papillis, Taeniogyrus tantulus, Trochodota epiphyka; myriotrochids Prototrochus burni, Prototrochus staplesi, Prototrochus taniae. Taeniogyrus heterosigmus Heding, Taeniogyrus roebucki (Joshua), Trochodota allani (Joshua) and Trochodota shepherdi Rowe are discussed. Keys are provided for southern Australian species of Taeniogyrus Semper and Trochodota Ludwig. A table is provided distinguishing Tasman Sea myriotrochid species.
