The taxonomic status of Petropedetes newtonii (Amphibia, Anura, Petropedetidae)
The taxon Petropedetes newtonii was described in 1895 by Bocage, from Bioko Island (Equatorial Guinea). This taxon, whose holotype is lost, has been misidentified since Boulenger’s revision of the genus in 1900 and its relationships with other taxa (P. vulpiae and P. johnstoni) is confusing. Currently, P. newtonii is considered a synonym of P. johnstoni. In this work, by revising morphological characters of non-webbed Petropedetes of Bioko, we demonstrate the morphological singularity of these specimens with respect to P. johnstoni and P. vulpiae and their association with the name Petropedetes newtonii. Consequently, we provide the subsequent designation of a neotype of P. newtonii and revalidate this species from its synonym with P. johnstoni.
