Comparative phylogeography allow us to understand how shared historical circumstances have shaped the formation of lineages, by examining a broad spectrum of co-distributed populations of different taxa. However, these types of studies are scarce in the Neotropics, a region that is characterized by high diversity, complex geology, and poorly understood biogeography. Here, we investigate the diversification patterns of five lineages of amphibians and reptiles, co-distributed across the Choco and Andes ecoregions in northwestern Ecuador. Mitochondrial DNA and occurrence records were used to determine the degree of geographic genetic divergence within species. Our results highlight congruent patterns of parapatric speciation and common geographical barriers for distantly related taxa. These comparisons indicate similar biological and demographic characteristics for the included clades, and reveal the existence of two new species of Pristimantis previously subsumed under P. walkeri, which we describe herein. Our data supports the hypothesis that widely distributed Chocoan taxa may generally experience their greatest opportunities for isolation and parapatric speciation across thermal elevational gradients. Finally, our study provides critical information to predict which unstudied lineages may harbor cryptic diversity, and how geology and climate are likely to have shaped their evolutionary history.

“…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.…”

“…Tadpole: Not described. Distribution (Figure 94): Espadarana durrellorum is known from few localities on the foothills of Cordillera Oriental and the Amazonian lowlands of Ecuador, at elevations of 300-1267 m [176,180]. Conservation status: Globally, E. durrellorum is Least Concern by the IUCN [181]; the species is known from few confirmed records, and a re-evaluation of its conservation status may be required.…”

Glassfrogs of Ecuador: Diversity, Evolution, and Conservation

et al. 2020

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.
