The small arboreal frog Guibemantis liber (Anura: Mantellidae) has served as an example for the existence of deep conspecific lineages that differ by a substantial amount in mitochondrial DNA but are similar in morphology and bioacoustics and thus ar

The taxonomic status of the strabomantid frog species Pristimantis nebulosus (Henle, 1992), originating from the southern Cordillera Azul in central Peru, is investigated based on examination of the holotype and its comparison with freshly collected
