Range Description

Some uncertainty surrounds the taxonomic status of the northern (L. flavipunctata of Courtice and Grigg 1975) and southern populations of Litoria castanea. Thomson et al. (1996) suggest that the northern and southern populations represent one species consisting of two disjunctive isolates separated by a distance of about 500km (see also map in Osborne, Littlejohn and Thomson 1996). The northern population was known from a relatively restricted distribution centred around the town of Guyra on the New England Tableland at altitudes between 1,000 and 1,500m asl (White and Ehmann 1997a; Mahony 1999). It occupied the headwaters of the west flowing Booroolong Creek and to a lesser extent those of the east flowing Anne River and Sarah River (Heatwole et al. 1995). Near Armidale, the species has been recorded from Commissioners Waters, a tributary of the east flowing Gara River (Heatwole et al. 1995). There are 13 known sites in the region (most above 1,000m asl) all of which have been verified by examination of museum specimens or photographs (Mahony 1999). The southern population has a restricted distribution between Canberra and Bombala on the Southern Tablelands at altitudes between 700 and 800m asl (Mahony 1999). The southern population was broadly sympatric with L. aurea in the north of its range and with L. raniformis in the south-west of the region (Mahony 1999).
