We describe a new species of Pristimantis from upper montane forests and high Andean grasslands of the Pui Pui Protected Forest and its close surroundings, Región Junín, central Peru. The description of the new species is based on 34 specimens found at elevations between 3400 and 3936 m a.s.l. Pristimantis attenboroughi sp. n. is characterized by a snout-vent length of 14.6-19.2 mm in adult males (n = 21), 19.2-23.0 mm in adult females (n = 10), and is compared morphologically and genetically with other taxonomically and biogeographically relevant species of Pristimantis. The new species is characterized by having narrow digits that lack circumferential grooves, irregularly shaped, discontinuous dorsolateral folds, and absence of both tympanic membrane and tympanic annulus. The high similarity in morphology between P. attenboroughi sp. n. and members of the Andean genera Phrynopus and Bryophryne provides an example for convergent evolution, and highlights the importance of using molecular data to justify generic assignment. Pristimantis attenboroughi sp. n. is most similar to Phrynopus chaparroi from the Región Junín, suggesting that the generic placement of this species needs to be revised. Phylogenetically the new species belongs to the Pristimantis danae species Group, a clade that includes several Pristimantis species distributed in the montane forests of central Peru, including P. albertus, P. aniptopalmatus, P. ornatus, and P. stictogaster.

A new species of Craugastoridae frog encountered from 1000-1700 m in elevation in the premontane forests of the Peruvian central Andes is described. The new species is similar in appearance to many other species of Pristimantis, but is easily distinguishable from these species by having bright red coloration on the groin, posterior surface of thighs, and shanks. The new species is only known for two localities 27 km apart in the Huánuco Region. Resumen Describimos una nueva especie de rana de la familia Craugastoridae de los bosques premontanos de los Andes centrales peruanos, los especímenes fueron encontrados entre los 1000-1700 metros de elevación. Esta especie es similar en apariencia a muchas especies de Pristimantis, sin embargo es facilmente distinguible por tener ingles, superficie posterior de los muslos y de la tibia rojo brillante. La nueva especie es conocida solo de dos localidades en la Región Huánuco, ambas separadas por alrededor de 27 km.

A new species of frog of the genus Pristimantis is described from a montane forest between 1700 and 1800 m a.s.l. of the Pui Pui Protected Forest (Región Junín) in central Peru. Pristimantis ashaninka sp. n. is described based on five adult females (snout-vent length 23.1-26.7 mm) and ten juveniles (snout-vent length 10.6-13.4). It differs from its congeners by having the skin on dorsum shagreen with many conical tubercles giving it a spinose appearance, lacking a tympanum, having groin, anterior and posterior surfaces of thighs uniformly grayish brown, and a pale bronze iris with fine black reticulations, a median reddish hint horizontally across iris, and a black narrow vertical streak from pupil across lower and upper half of iris. Among the Peruvian Pristimantis that lack a tympanum, P. ashaninka sp. n. is morphologically most similar to P. lirellus, P. martiae, and P. rhabdocnemus. However, 16S DNA barcoding revealed clear distinctions between all four species of Pristimantis.
Pristimantis myersi is a small Andean frog that inhabits paramos, sub-paramos and upper Andean forests at elevations between 2,900-3,275 m. It is known from about a dozen localities in the southern end of the Cordillera Central of the Colombian Andes. Herein, we report for the first time the presence of this species in Ecuador, based on ten specimens from three localities in the provinces of Imbabura and Sucumbíos. The species' range is extended and a distribution map with the Ecuadorian records is provided.

A new frog of the Pristimantis myersi Group is described from a bamboo patch within the Reserva Ecológica Verdecocha (0°5'46.9"S, 78°36'15.3"W; 2851 m), located at northwestern flank of the Volcán Pichincha, in the vicinities of Quito, Ecuador. The new species is known from eight adult males, whereas the females remain unknown; it can be readily distinguished from all species of the P. myersi Group that inhabit the highlands of the Ecuadorian Andes by the unique combination of the following characters: body small (adult male SVL 14.9-19.7 mm; females unknown); dorsal skin shagreen, with a barely visible middorsal raphe, scapular and dorsolateral folds; tympanum small but well-defined; upper eyelid with one enlarged tubercle; males with prominent vocal slits, but without nuptial pads on thumbs; fold-like tarsal tubercles. With this new species, the number of Pristimantis assigned to the P. myersi Group raises to 16, of which, 12 are in Ecuador. We provide notes on morphology and color variation, advertisement call, and natural history of the new species.

We describe two new species of Pristimantis from the Kosñipata valley in the eastern slopes of the Andes near Manu National Park, Peru. The two new species are closely related but do not overlap elevationally: P. antisuyu sp. n. occurs from 1485-1823 m a.s.l., whereas P. erythroinguinis sp. n. occurs from 930-1255 m a.s.l. Both species are readily distinguished from all other species of Pristimantis but P. cruciocularis and P. flavobracatus by possessing an iris with a cruciform pattern, no tympanum, and red bright or yellow coloration on groin. We used a Maximum Likelihood approach to infer a molecular phylogeny on a dataset composed of 27 terminals and 903 bp of the concatenated 16S rRNA and COI mitochondrial fragments. Our phylogenetic analyses indicate that, despite differing in groin coloration from red to yellow, individuals of P. cruciocularis and P. flavobracatus form a single clade, and some specimens have identical 16S sequences. Therefore, we synonymize P. flavobracatus w...
New country records for five species of Pristimantis Jiménez de la Espada, 1870 from Ecuador
Five new species of frogs from the genus Pristimantis are reported for Ecuador, thus extending the distribution range for these species, previously described only for the southern Andes of Colombia and the northern Andes of Peru. The diversity of Pristimantis in Ecuador increases to 148 species, adding five additional species to the total of 508 anurans already described for Ecuador.
We describe four new species of terrestrial-breeding frogs belonging to the genus Phrynopus from specimens collected on the eastern slopes of the Cordillera Oriental (2800–3850 m) near and within Río Abiseo National Park, Provincia Mariscal Cáceres, Departments of San Martín and La Libertad, northeastern Peru. All four species lack a visible tympanum and inhabit the upper ridges and slopes within or adjacent to the Park. Phrynopus anancites sp. nov. and P. capitalis sp. nov. inhabit the wet montane grasslands on the upper ridges and valleys from 3600 to 3850 m. Phrynopus anancites (SVL = 25.3 mm) has coarsely aerolated skin and olive green coloration and has small vomerine teeth, while P. capitalis (female SVL = 35.6 mm) is characterized by a large head, short limbs, and distinctive dorsal pattern. Phrynopus dumicola sp. nov. (female SVL = 25.3 mm) has a short head and dark colored body with granular skin on the flanks, and is known only from forest patches along the treeline from 3225 to 3550 m, whereas P. personatus sp. nov. (female SVL = 28.2 mm) has a dark facemask and bright yellow groin spots (possibly aposematic), and inhabits a narrow band of continuous tropical montane rain forest from 2890 to 3110 m. We report infection with Batrachochytrium dendrobatidis from one specimen of P. dumi-cola collected in July of 1988. With the addition of these four new species, Phrynopus now includes 32 nominal species.
