Abstract

Eight species of flatworm were identified during a survey of 7 alpine areas in 1993, including 3 species of Spathula (Tricladida : Dugesiidae), 4 undesciibed species and Reynoldsonia reynoldsoni Ball (Tricladida : Dugesiidae). Spathula tryssa Ball was relatively common and widespread in two adjacent areas, despite being listed under the Flora and Fauna Guarantee Act 1988. Current levels of land use do not appear to be threatening the species with extinction, although cattle grazing may be a localised problem. The IUCN conservation status of the species should be seen as Lower Risk Least Concern. Of the remaining species, two (S. gourbaultae Ball and an undescribed species) have very restricted disuibutions on Mt Donna Buang and Mt Stirling respectively, and should be considered to be Vulnerable and Critically Endangered respectively. Three of the species (S. agelaea Hall & Ball, R. reylloldsoni and a further undescribed species) appear to be either widespread or secure, deserving a Lower Risk Least Concern category, one undescribed species has insufficient data to determine a conservation status (Data Deficient) and the final species (undescribed) requires further taxonomic investigation before conclusions can be drawn.
