Original name: Glacidorbis isolatus Ponder & Avern, 2000. In Ponder, W.F. & Avern, G.J. (2000). The Glacidorbidae (Mollusca: Gastropoda: Heterobranchia) of Australia. Records of the Australian Museum. 52: 307 - 353.
Type locality: Swamp southeast of Munro Hut, Kerripit River tributary, Barrington Tops, New South Wales.
This species occurs in small streams, springs and swamps, and amongst moss and roots of water plants, in the Great Dividing Range of north-eastern New South Wales.
North-eastern NSW where it is known from Barrington Tops and Gloucester Tops, NSW where it is broadly sympatric with G. hedleyi, although so far not living together. Also from one locality in the New England area.
Glacidorbis isolatus only occurs in a small area of north-eastern New South Wales - it is the only keeled species known from that state.
