We describe a new species of Pristimantis from the Tinajillas-Rio Gualaceño Ecological Conservation Area, Morona Santiago province, an area montane forest in southeastern Andes Ecuador. nimbus sp. nov. is similar to P. altamazonicus, ardyae, bambu, bellator, caeruleonotus, cethospilus, churuwiai, croceoinguinis, cryptomelas, diadematus, flavobracatus, gualacenio, nigrogriseus, ventrimarmoratus, and versicolor which it can be distinguished by presence flash marks on flanks, groin, arm...

We describe a new species of Lynchius from the eastern montane forest southern Ecuador. also report occurrence L. parkeri in Ecuador, on paramos Yacuri National Park, near border with Peru. used morphological and genetic evidence for description parkeri. Phylogenetic analyses were carried out using both maximum likelihood Bayesian inference DNA sequences mitochondrial nuclear genes. The phylogeny shows that simmonsi is sister to clade composed remaining flavomaculatus. has prominent heavily...

Elachistocleis is a Neotropical genus of microhylid frogs with 18 species, most which occur east the Andes in South America. Here, we present new phylogeny Gastrophryninae and describe name species from southern Ecuador—the first to be found west also Ecuador. Our based on DNA sequences mitochondrial genes 12S rRNA, 16S COI, nuclear BDNF, cmyc2, H3A, 28S, SIA1, Tyr. araios sp. n., sister all other Elachistocleis. The finding this taxon highlights probability existence more Andes.

In the genus Pristimantis, species are often combined into taxonomic units called groups. The taxonomy of these groups is frequently inaccurate due to absence genetic data from type series and repeated misidentifications generated by high morphological resemblance between taxa. Here, we focus on P.orestes group, providing first assessment sensu stricto individuals collected locality, with a reviewed diagnosis description advertisement calls. We find that two lineages previously named...

A new species of Pristimantis is described from the highland paramos on eastern slopes Cajas Massif, southern Andes Ecuador, at 3400 m. This characterized by having a distinctive reddish color, cutaneous macroglands in suprascapular region and surfaces arm legs, lacking dentigerous processes vomers. The are similar to those exhibited several orcesi group, may suggest close phylogenetic relationship. could be latitudinal substitution Ecuador.ResúmenDescribimos una nueva especie de desde las...

Se describen dos especies nuevas de Pristimantis los bosques nublados y páramos protegidos por la Reserva Municipal Tinajillas-Gualaceño, provincia Morona-Santiago, vertiente suroriental Andes Ecuador. La primera especie habita entre 1900 a 2250 m se diagnostica presencia discos digitales espatulados colación marrón oscuro (machos con ingles naranja). segunda 3200 exhibe una distintiva coloración inguinal fondo amarillo manchas negras, un tubérculo subcónico en el hocico tímpano presente.

We present new records for Fleischmann's Glassfrog, Hyalinobatrachium fleischmanni (Boettger, 1893), which extend the distribution of this species into central and southwestern Ecuador thus represent southernmost known localities. These reports are based on specimens collected at Cerro de Hayas, province Guayas, Macul, Los Ríos. localities geographic range H. by approximately 250 km south previous occurrences.

We describe a new glandular terrestrial frog of the Pristimantis (Anura: Craugastoridae) genus. The species inhabits high montane forests Cañar province in southern Ecuador. It differs from other frogs by having striking dark gray and red dorsal coloration, skin with corrugated texture, small tubercle on eyelid heel, absence vomerine odontophores, large patches supratympanic area, arms limbs. Our molecular analyses show that is clade P. orcesi erythros. Based our results, we redefine group...

Abstract The genus Pristimantis diversified in the tropical Andes mountains and is most speciose of terrestrial vertebrates. are notable among frogs that they thrive at high elevations (>2,000 m) direct developers without a tadpole stage. Despite their ecological significance, little known about genetic physiological traits enabling success. We conducted transcriptomic analysis on seven species sampled across Ecuadorean to explore three hypotheses for success: (i) unique genes under...

We present new information on the distribution of marsupial frog Gastrotheca testudinea (Jiménez de la Espada, 1870) in Ecuador. provide first record from province Cañar, and southernmost locality for Ecuador (which also corresponds to third known report Zamora-Chinchipe). In addition, we review the elevation range species, propose change lowest elevation limit G. 1100 700 m.

RESUMENEn este estudio, basándonos en evidencias morfológicas y moleculares, describimos una nueva especie del género Pristimantis que habita las montañas valles áridos de la provincia Azuay, incluyendo zonas urbanas periurbanas ciudad Cuenca. La se destaca por presentar textura dermal externa fuertemente granulada, papilla proyectada punta hocico un canto advertencia consiste series combinadas tres dos notas, Morfológicamente, es similar con P. cajamarcensis, ceuthospilus, jimenezi,...

We present new information on the distribution of marsupial frog Gastrotheca testudinea (Jiménez de la Espada, 1870) in Ecuador. provide first record from province Cañar, and country’s southernmost locality (which also corresponds to third known report Zamora-Chinchipe). In addition, we discuss validity Loreto for this species. Based discussion, review elevation range species propose change lowest limit 1100 700 m.
