A New Species of Telmatobius Wiegmann, 1834, from the Eastern Cordillera Central of the Andes, Peru (Anura: Telmatobiidae), with Description of Its Tadpole, and Range Extension of T. mendelsoni De La Riva et al., 2012

ABSTRACT We describe adult specimens and tadpoles of a new species of Telmatobius Wiegmann, 1834, Telmatobius mantaro, from the central Cordillera of the Andes in Peru. Specimens were collected in humid lower montane forests and dry lower montane forests between 2240–3170 m elevation at the northern parts of the Departments of Huancavelica and Ayacucho. We also report a range extension of 262 km west of the type locality for Telmatobius mendelsoni De la Riva et al., 2012, which was found in sympatry with T. mantaro in Ayacucho. The new species has a snout-vent length of 48.9–55.8 mm in three adult males, and both sexes have tympanic membrane differentiated and tympanic annulus visible, a feature that distinguishes the new species from the majority of other Peruvian Telmatobius. We propose to assign the IUCN category Critically Endangered to this species because of its small area of distribution and its high likelihood of being infected by Batrachochytrium dendrobatidis.
