Description of a new moss frog from the south-western Cape (Anura: Ranidae: Arthroleptella)

Abstract

A new species of moss frog, genus Arthroleptella, is described from the Kleinrivier mountains of the south-western Cape. It is morphologically indistinguishable from the other three species in the area. The four Cape species are allopatric, each has a unique male advertisement call, and preliminary molecular data shows consistent differences.
