The Sunset Frog is one of the oldest WA frogs, estimated to have diverged from its closest relatives (Uperoleia spp.) at least 30 million years old. It is quite distinct from other Australian frogs and was only discovered in the early 1990s and described in 1997. Owing to its small distribution it is listed as 'vunerable'.
