[Herpetology • 2010] Taxonomic review of Physalaemus olfersii with revalidation of P. lateristriga and description of two new species

Physalaemus orophilus sp. nov.

Physalaemus olfersii was described by M.H.K. Lichtenstein and E.K. Martens in 1856 based on two syntypes collected by I.M. Olfers between the years 1818 and 1819. Due to the brevity of it’s original description and high interpopulational variation, a taxonomic review of material assigned to the species is proposed. Morphological comparisons allowed us to associate the syntype of P. olfersii to populations distributed between the state of Espírito Santo and of São Paulo to which the southern limit is the to the municipality of São Paulo. Historical documents allowed us to define an area within Serra do Mar mountain range as the type locality of the species. Morphological and acoutics comparisons of P. olfersii from different localities in southern and southeastern Brazil revealed considerable variation among populations. Differences in call parameters and morphology, led us to conclude that three more species where under the name P. olfersii: Physalaemus lateristriga (Steindachner, 1864) comb. nov. and two new species, Physalaemus feioi sp. nov. and P. orophilus sp. nov.
