Abstract
Fluviopupa kessneri n. sp. is described from the Mulgrave River and one of its major tributaries, the Little Mulgrave River, in north-east Queensland. It is the first record of the Fluviopupa group from a continental area, other members of the genus being known only from Fiji, New Guinea and a few other Pacific Islands, including New Caledonia.
