A NEW SPECIES OF THE PROSOBRANCH GASTROPOD GLACIDORBIS AND ITS IMPLICATIONS FOR THE BIOGEOGRAPHY OF SOUTH-WESTERN AUSTRALIAWA Museum Records and Supplements | Updated 1 decade agoAbstract Minute snails found in streams of the Darling Range, Western Australia, are described here as a new species, Glacidorbis occidentalis. Glacidorbis has a southern distribution, occurring in south-eastern Australia, Tasmania, and southern Chile. Its presence in south-western Australia is consistent with theories proposing a common Gondwanic origin for much of this region's freshwater fauna and that of south-eastern Australia.
