Abstract
Three species of Phrynomantis Peters, 1867, have been historically recorded for Angola: P. affinis, P. annectens and P. bifasciatus. As noted by all authors who have dealt with specimens of P. bifasciatus from the country, the Angolan population is characterized by an odd coloration pattern for the species, which led Boulenger to consider it a different variety. A revision of the extant specimens of Angolan Phrynomantis available in natural history collections, specimens collected in recent field surveys, as well as recent sightings and photographs allows the recognition of the Angolan population of P. cf. bifasciatus as a new species, endemic to the coastal lowlands of western Angola. The new taxon is described solely based on its coloration pattern and morphology, and it is separated from nominotypic P. bifasciatus by more than one thousand kilometers. The revision of these historical specimens also allowed us to confirm a second record of P. affinis in the country and to contribute to an overall better understanding of the distribution of the species of the genus on the continent.

A coloração peculiar de uma rã colhida em Angola no início do século XX por Francisco Newton levantou suspeitas. O exemplar desta nova espécie foi batizado com o nome do explorador tripeiro.
