Abstract:

Substantial molecular and morphological character differences lead us to the description of a new species of the genus Pristimantis from the cloud forest of Cerro Chucantí, Maje Mountains, Darien Province, as well as from several other mountain ranges in eastern and central Panama. Pristimantis gretathunbergae sp. nov. is a sister species to the allopatric P. erythropleura-penelopus group from northern Colombia with a mtDNA sequence divergence of > 4.4% at 16S and > 14.6% at COI. Its closest congener in sympatry is P. cruentus that differs by a large sequence divergence of > 9.6% in 1

Abstract:

Continuous field work on mountains in the upper Pastaza watershed, showed an unexpected cryptic diversity in the recently described <i>Pristimantis anaiae</i> species group. Based on molecular and morphological characters we describe a new frog species from the central region of the eastern Ecuadorian Andes. We present an updated phylogeny for the <i>Pristimantis anaiae</i> species group, based on widely used, ubiquitous, and available genes, three mitochondrial genes (12S rRNA, 16S rRNA, ND1) and RAG1 nuclear gene. Our phylogenetic hypothesis increases genetic diversity of the species group a

Abstract:

We describe three new species of terrestrial frogs of the genus Pristimantis from the province of El Oro, southwestern Ecuador. Two species inhabit the lowland semi-deciduous forests, and the third species in the high montane forests. Pristimantis kuri sp. nov. is characterized by having white patches bordered by dark brown on ventral, inguinal and hidden surfaces of legs, “H” occipito-escapular dermal ridge, and a conical tubercle on the upper eyelid. Pristimantis allpapuyu sp. nov. shows dark brown dorsum with conspicuous cream bands, long and thin digits, and two to three subconical tubercl

Describimos a Pristimantis loujosti sp. nov. de la cuenca alta del río Pastaza. La especie se caracteriza por su tamaño corporal grande, piel glandular gruesa, coloración de las superficies ocultas de las patas e ingles de color naranja, un pliegue prominente en la superficie superior de la base de la mano, uno a tres tubérculos aplanados en la superficie anterior del antebrazo e iris fuertemente reticulado. La presencia del pliegue en la mano no ha sido reportado antes en otros Pristimantis aunque no parece ser exclusivo de Pristimantis loujosti, ya que también ha sido observado en P pycnoder

Una nueva especie de rana del género Pristimantis es descrita de los bosques nublados de la cuenca alta del río Pastaza, en la vertiente oriental de los Andes centrales de Ecuador. Pristimantis tungurahua sp. nov. se caracteriza por la ausencia de crestas craneales y sacos vocales, presencia de tímpano y anillo timpánico, tubérculos cónicos en el párpado y talón, y en particular porque las hembras presentan una coloración rojiza muy llamativa en las ingles, axilas y superficies ventrales (en machos el color rojizo se restringe a ingles y axilas).

Abstract:

Abstract Species richness in the genus Pristimantis is underestimated due to the existence of morphologically cryptic species. This is worsened by the low sampling effort and the lack of studies using genetic markers. Here, we use molecular and morphological data to determine the phylogenetic relationships of a clade of Pristimantis distributed throughout montane tropical forests in the eastern Andes, from central Ecuador to northern Perú. We name this clade the Pristimantis trachyblepharis species group. Our results show that it comprises nine species, of which four are formally described and

Abstract:

We describe a new minute species of the genus Pristimantis, P. boucephalus sp. nov., from the Yanachaga-Chemillén National Park, Región Pasco, Peru. The description is based on a freshly collected male specimen found at 2950 m a.s.l. in a cloud forest and four previously unidentified museum specimens consisting of two adult males, one subadult female and a juvenile from the Yanachaga-Chemillén National Park. The new species is mainly characterized by a snout–vent length of 13.4–14.5 mm in adult males (n = 3), and 12.5 mm in the only known subadult female, and is compared morphologically and ge
