Abstract

One new genus and two new species of camaenid are described from geographically remote lithorefugial habitats in Queensland. The two habitats have contrasting environments characterised by radically different geology, climate and vegetation. Lorelliana gen. nov. is introduced to accommodate L. hoskini sp. nov. from the high rainfall, rainforest peppered, granitic lithorefugia of Cape Melville, Cape York Peninsula. Quistrachia nevbrownlowi sp. nov. is described from the quartzic limestone refugia of the low rainfall, often drought affected, spinifex grassland of Mt Unbunmaroo (= Black Mountain), south-western Queensland. The survival of each species is discussed in relation to the significance of lithorefugia as habitat for land snails in otherwise snail-hostile environments.
