Abstract
Rana laterimaculata Barbour et Noble, 1916 had been previously regarded as a junior synonym of R. baramica Boettger, 1901 by Inger (1966). An examination of literature, photographs, and live and preserved specimens revealed that visible and audible differences were apparent between two ‘forms’ of R. ‘baramica’, which may even be sympatric in some localities. The acoustic characters of the two ‘forms’ are analysed and compared. Rana laterimaculata is here recognized as a valid species and a neotype is assigned in place of the missing holotype. The species is redescribed and diagnostic differences separating it from R. baramica are explained. The present known distribution of both species is provided. Both species are confined to the Sunda region.
