New Freshwater Triclads from Tasmania (Platyhelminthes, Turbellaria)

Abstract

Three new freshwater triclads are described from Tasmanian lakes. Two of these represent the first records of the genus Spathula in Tasmania and the third belongs to the endemic genus Romankenkius. The taxonomic affinities of the species are discussed and keys to all the Tasmanian genera and species are provided. These keys are to be regarded as provisional since it is likely that there remain many planarian species to be discovered and described from Tasmania.
