“…Calls are emitted in series; a typical call series has four or five calls (mean Tadpole: Not described. Distribution (Figure 87): Espadarana audax occurs through the Eastern Montane region of southeastern Colombia, Ecuador, and northern Peru at elevations between 800 and 1900 m. This species has been recorded from the provinces of Napo, Morona Santiago, Sucumbíos, and Zamora Chinchipe in Ecuador, the departments of Huila (eastern slope of Cordillera Central), Putumayo, Cauca, Caquetá, and Boyacá (eastern slope of Cordillera Oriental) in Colombia, and the Department of San Martín in Peru ( [19,22,[174][175][176], this work). In Ecuador, the species is found within the Eastern Foothill Forest and Eastern Montane Forest ecoregions.…”

“…Taxonomic Remarks: The morphological differences that separate Espadarana durrellorum and E. audax are subtle, but given the available genetic and morphological data, we consider them as valid species. "Centrolene" fernandoi was recently placed in the synonymy of E. audax [175].…”

Glassfrogs (family: Centrolenidae) represent a fantastic radiation (~150 described species) of Neotropical anurans that originated in South America and dispersed into Central America. In this study, we review the systematics of Ecuadorian glassfrogs, providing species accounts of all 60 species, including three new species described herein. For all Ecuadorian species, we provide new information on the evolution, morphology, biology, conservation, and distribution. We present a new molecular phylogeny for Centrolenidae and address cryptic diversity within the family. We employ a candidate species system and designate 24 putative new species that require further study to determine their species status. We find that, in some cases, currently recognized species lack justification; specifically, we place Centrolene gemmata and Centrolene scirtetes under the synonymy of Centrolene lynchi; C. guanacarum and C. bacata under the synonymy of Centrolene sanchezi; Cochranella phryxa under the synonymy of Cochranella resplendens; and Hyalinobatrachium ruedai under the synonymy of Hyalinobatrachium munozorum. We also find that diversification patterns are mostly congruent with allopatric speciation, facilitated by barriers to gene flow (e.g., valleys, mountains, linearity of the Andes), and that niche conservatism is a dominant feature in the family. Conservation threats are diverse, but habitat destruction and climate change are of particular concern. The most imperiled glassfrogs in Ecuador are Centrolene buckleyi, C. charapita, C. geckoidea, C. medemi, C. pipilata, Cochranella mache, Nymphargus balionotus, N. manduriacu, N. megacheirus, and N. sucre, all of which are considered Critically Endangered. Lastly, we identify priority areas for glassfrog conservation in Ecuador.

“…The range height of perching between 1.5 -2 m tend to provide favorable conditions to reduce predation by small terrestrial mammals on individuals or eggs. However, it does not represent a risk to the survival of tadpoles because of the impact when they hit the water (Hampton and Otto, 2014;Cisneros-Heredia and Guayasamin, 2014).…”

to determine the population status of Centrolene savagei (Centrolenidae) in the Western and Central Andes of Colombia. Scope: promotion of the population study of the endemic glassfrogs species of Colombia. Methodology: C. savagei (Centrolenidae) has only been registered in the Central and Western Andes of Colombia. We conducted a visual encounter survey in eight different localities where C. savagei was previously reported: Alto Bonito, Florencia, La Pastora, Santa Rosa de Cabal, Filandia, Boquía, Alto el Otoño and Chicoral, with an effective sampling effort of 54 h per locality. Each captured individual was marked, sexed and the height above water level of the perch was registered. Furthermore, all detected clutches in each survey were also marked and height above water level was recorded. We use a standard capture-recapture model to estimate the size of the population in each study site assuming closed population conditions. Main Results: C. savagei was absent at La Pastora and Florencia. In all localities where C. savagei was registered, male individuals and clutches were usually found between 1.5-2.0 m, while female individuals remain most of the time above 6 m height, and only go down for reproduction. The population size of C. savagei in the study area of Alto del Otoño was 132 ± 13 ind, in Chicoral was 41 ± 8 ind and in Santa Rosa de Cabal was 37 ± 6 ind. In Filandia, Boquia and Alto Bonito, recaptures were not carried out, so the size of the population could not be estimated. Conclusions: The presence of C. savagei in 75% of the localities where it had previously been reported suggests that the biotic and abiotic conditions in these sites are still adequate to sustain populations of this endemic species.

Peru is well known for amphibian diversity and endemism, yet there have been relatively few field studies of glassfrog (Centrolenidae) diversity in this country. Research in Colombia and Ecuador indicates that centrolenid diversity is higher in the northern Andes. However, part of this trend appears to be due to sampling effort. We conducted fieldwork throughout northern Peru, and based on phylogenetic analysis of DNA sequences, combined with bioacoustic and morphological analyses of new and available material we now recognize 33 species from the country (versus 30 species prior to this work). Field surveys led to the discovery of four remarkable species: Centrolene charapita new species is a large, ornamented glassfrog that appears to be sister to Ce. geckoideum; Chimerella corleone new species represents the second-known member of the genus Chimerella; Cochranella guayasamini new species is the second-known member of the genus with humeral spines; and Hyalinobatrachium anachoretus new species occurs in the cloud forest of the east-Andean versant in Peru. In addition to the new species described here, we provide new country records, new localities including range extensions of up to 875 km, information on diagnostic characters and phylogenetic relationships, call and larval descriptions, and observations on natural history for several Peruvian centrolenids. Our results also revealed several taxonomic problems concerning species of the genus Rulyrana, and we conclude that R. croceopodes and R. tangarana are junior synonyms of R. saxiscandens. By implication of our phylogenetic analyses, we recognize the following new combinations: Espadarana audax new combination, Espadarana durrelorum new combination, and Espadarana fernandoi new combination.
