The rather elongate, cylindrical shaped shell has about five whorls and often has a reddish hue. The aperture is much longer than the spire and the inner lip expanded over the parietal wall.

Several synonyms were recogised by Hubendick (1951) but there has not been a more recent taxonomic evaluation of these.
On submerged water plants in ponds, swamps and poorly drained pasture. Biology similar to other lymnaeids.
This widely distributed Asian species has been recorded from South Africa and Enogerra Creek, Brisbane (Boray, 1978).
Known to transmit Fasciola gigantica of cattle and sheep in SE Asia and Indonesia. Also intermediate host of a number of other parasites.
Treated as a race of Lymnaea auricularia Linnaeus, 1758 by Hubendick (1951).
