We describe for the first time the call of Rhinella festae (Peracca, 1904), recording it in captivity inside a plastic bag. The call is composed of 1 to 2 multi-pulsed notes (2–5 pulses), has an average duration of 0.72 s, and a dominant frequency of 1.40 kHz. This species is characterized by the absence of vocal slits and sacs, so the emission of...

We provide several lines of evidence to delimit a new species of Hyloscirtus and define its phylogenetic position inside the Hyloscirtus bogotensis group. The new species is the sister taxon to Hyloscirtus mashpi and is related to a clade formed by H. alytolylax and a putative new species from the province of El Oro in, southwestern Ecuador. Hylosc...

The Province of Carchi is a strategic area, where the most important remnants of tropical forests of the Ecuadorian Chocó come together. These contact the western foothills of the Andes, between the Mira and San Juan river basins, and ascend to the paramo platforms above 3400 meters in altitude and all the way to 4800 meters. This impressive altitu...

This note describes the advertisement calls of Rhaebo haematiticus, recorded in Tobar Donoso, province of Carchi‒Ecuador, providing for the first time a quantitative analysis of its spectral and temporal variables. The calls of three populations were analyzed and compared with calls of Rhaebo blombergi and Rhaebo guttatus, two species of the genus...

A new species of frog of the genus Pristimantis is described from the paramos of the Nudo de Cajanuma, Podocarpus National Park, on the border between the provinces of Loja and Zamora-Chinchipe, Ecuador. The new species is readily distinguished from all other species of Pristimantis by its large body size (snout-vent length: 50.0–50.5 mm in adult f...

p>We describe a new species of terrestrial frog of the genus Pristimantis , located in the south Andes of Ecuador. The new species is characterized by: presence of dentigerous processes of vomer that are triangular in outline; ulnar tubercles flattened and disposed in a longitudinal, fold-like row; and a distinctive ventral coloration light to dark...

A new frog in the genus Pristimantis is described from a cloud forest on the western flanks of the Cordillera del Cóndor and eastern Andean slopes in the province of Zamora Chinchipe, southeastern of Ecuador. We inferred its phylogenetic position using DNA sequences of mitochondrial and nuclear genes. The new species is strongly supported as part o...

Pristimantis es el grupo más diverso de vertebrados a nivel mundial, ya que aglutina alrededor del seis por ciento de la diversidad total de anfibios del mundo (587 especies) y el 15% de las especies del Neotrópico. En Ecuador, de 587 especies de anfibios reportadas, más de un cuarto (200 especies) son Pristimantis. Se describen un promedio de 4 es...

We describe a small frog of the genus Pristimantis inhabiting bromeliads (snout-vent length 20.3‑23.3 mm in females, 16.1‑17.4 mm in males), from a remote sandstone plateau of the Cordillera del Condor, in southeastern Ecuador, with an altitudinal range of 2,045‑2,860 m. A phylogeny based on sequences of DNA (mitochondrial and nuclear genes) suppor...

We provide information about the composition of the terrestrial frogs of the genus Pristimantis in the upper basin of the Upano River, located on the Eastern slope of the Andes Mountain range in the Morona Santiago province, south-east of Ecuador. The compendium of the 37 species comes from collections conducted on an altitudinal gradient of betwee...

We describe a new species of frog of the genus Chiasmocleis from the montane forests of southeastern Ecuador, at the western slopes of Cordillera del Cóndor, between 1,224‑1,630 m of elevation. Based on new sequences of mitochondrial and nuclear DNA we present phylogenetic relationships of the new species and its congeners. The phylogeny shows a cl...

We describe a new species of climbing rat of the genus Rhipidomys based on cranial and external morphology, morphometrics, and phylogenetic analyses of cytochrome b gene. This taxon was compared with species of Rhipidomys present in Ecuador, principally R. latimanus, which is a closely related species based on molecular analysis, and with several s...

En los meses de diciembre y febrero del 2010-2011 se realizaron estudios en el complejo lacustre de Sardinayacu, localizado en el Parque Nacional Sangay, en los cuales se trabajó 10 días. El objetivo de este estudio fue analizar y describir bioacústicamente las vocalizaciones de los anuros en la laguna Cormorán (una de las lagunas del complejo lacu...

We describe Pristimantis tinguichaca sp. nov., a member of the Pristimantis unistrigatus species group, from the cloud forests of Sangay National Park located on the eastern slopes of the Andes in southeastern Ecuador. The new species was collected in cloud forests and cattle pastures at 2,750–2,830 m elevation. It differs from other members of the...

We described the vocalizations of Pristimantis ganonotus, from recordings made in June 2014 in Complejo Lacustre de Sardinayacu (Parque Nacional Sangay, Ecuador). We analyzed the spectral and temporal parameters of seventy calls recorded from five individuals. Based on the quantifications, we designate P. ganonotus as a species with a wide vocal re...

We report two new localities for Podiceps major in Ecuador: La Tembladera wetland and the Tahuín dam. At the last locality we found the first nest from Ecuador, for which we describe its structure and the building behaviour of the couple. Furthermore, we describe the courtship and territorial calls of the species. Resumen Reportamos dos nuevas loc...

We describe a new species, a medium size terrestrial frog (LRC 21.7‑24.9 mm in females, and 15.2‑17.8 mm in males); belong to the Pristimantis genus, from the sandstone plateau of the Cordillera del Condor at southeastern Ecuador, at 2300 m high. The new species differs from its congeners in Ecuador for its distinctive coloration pattern, ochraceou...
