The Yellow-spotted Bell Frog (Litoria castanea) (Steindachner 1867) is a large (53 to 85 mm) terrestrial hylid frog belonging to the Australian Bell Frog complex. It is known from the New England Tableland and South Eastern Highland bio-geographical regions of south-eastern Australia (Heatwole et al.1995; Osborne et al.1996). Thomson et al. (1996) documented morphological differences between the New England Tableland and South Eastern Highland populations, but concluded that insufficient information was available to warrant recognition of the two forms as distinct species.
The Yellow-spotted Bell Frog is distinguished from other species of Bell Frogs by the fully webbed toes and the presence of black and yellow marbling on the ventral surface of the legs (Thomson et al. 1996).
The Peppered Tree Frog (Litoria piperata) (Tyler and Davies 1985) is a small (20 to 27mm) hylid frog belonging to the leaf green tree frog species complex. It is distinctive from other related species because of its small size, dorsal colour pattern of darker brown-grey peppering on a dark green background and lack of an obvious lateral stripe.
The Peppered Tree Frog occurs only within NSW with a geographic range extending from south of Armidale to the Gibraltar Range, comprising the headwaters of numerous rivers over an altitude range from 800 to 1000m AHD.
