Abstract

Memoirs of theQueensland Museum-Nature is the only free, on-line journal focussed on publishing peer reviewed research on Queensland, Northern Australia and the Torres Strait. Its key focus is on recording the biodiversity and geoheritage of Australia.

The family is considered to be a Gondwanan origin that has survived the vagaries of climate induced rainforest fragmentation since the Miocene. The vast majority of species now mainly live in moist humid rainforest and smaller isolated mesic refugia on mountain tops and in sheltered gullies. More recently, semi-evergreen vine thickets (dry rainforests) in the semi-arid Brigalow Lands bioregion have entered the spotlight of favoured habitats for these tiny snails (Stanisic 2020). In stark contrast, relatively few charopids have made the transition to the drier eucalypt forests an eastern Australia. This publication describes three new species of pinwheel snail from differing forest habitats in southern, central and mid-eastern Queensland and north-eastern New South Wales. These are variously assigned to Bindiropa gen. nov., Stanisicaropa Holcroft, 2018 and Gyrocochlea Hedley, 1924. An additional putative Gyrocochlea species from the Richmond Range, north-eastern New South Wales, represented by a single damaged shell, is figured but not formally described.
