“…Pristimantis most likely originated in South America, where it is most diverse (Duellman, 1999;Heinicke et al, 2007;Lynch, 1971), and spread into Central America as far north as Honduras (Duellman, 2001;Savage, 1982) in the Pliocene with the completion of the Isthmus of Panama, or perhaps earlier (Wang et al, 2008).…”

“…However, no thirdposition sites from ND2 or COI were used in the analyses (see below). Twenty-two samples were taken from Crawford and Smith (2005) and 14 were taken from Wang et al (2008) and detailed molecular laboratory techniques are provided in these two publications.

We describe a new species of Pristimantis (Anura: Strabomantidae) from the Pacific coast of the Darié n Province, Panama. The type locality is on Cerro Piñ a, in the Serranía de Sapo, at 700-800 m elevation. This new species is readily distinguished from all other known congeners from the region based on external morphology. Despite the small size of the two type specimens, histological analysis of the gonads shows these individuals were potentially reproductive males. Molecular phylogenetic analyses based on the ND2-WANCY mitochondrial gene region reveal that this new species is genetically distinct. Molecular and morphological data place the new species in the Pristimantis (Hypodictyon) ridens species series, and suggest that P. cerasinus be moved to this group as well. Molecular analyses also reveal a potential synapomorphy of the genus Pristimantis relative to the other five genera sampled here: the loss of the D-stem of the tRNA CYS gene. Our finding of another endemic frog from eastern Panama lends further support to the concept of the Darié n as a center of endemism and not just a conduit between continents.RESUMEN: Describimos una nueva especie del gé nero Pristimantis (Anura: Strabomantidae) de la costa del Pacífico de la Provincia de Darié n en Panamá. La localidad tipo es Cerro Piñ a a 700-800 metros sobre el nivel del mar. Con base en la morfología externa esta nueva especie es fácilmente distinguible de todas las otras especies conocidas en la regió n. A pesar del pequeñ o tamañ o de los dos especímenes tipo, análisis histoló gicos de sus gó nadas muestran que estos individuos eran machos potencialmente reproductores. Los análisis de filogenia molecular basados en la regió n de ADN mitocondrial ND2-WANCY revelan que la especie nueva es gené ticamente distinta. Los datos moleculares y morfoló gicos sugieren asignar tentativamente a la nueva especie dentro de la serie de especies ''Pristimantis (Hypodictyon) ridens'' y que la especie, P. cerasinus, debe ser incluida en este grupo tambié n. Los análisis moleculares tambié n revelan una posible sinapomorfía del gé nero Pristimantis en comparació n con los otros cinco gé neros incluidos en este análisis: la pé rdida de la ''rama D'' del gen ARNt CYS . El descubrimiento y descripció n de otra especie endé mica del oriente de Panamá da más apoyo a nuestro concepto del Darié n como un centro de endemismo y no só lo como una vía entre dos continentes.

“…Cryptic diversity in terraranan lineages has been observed on multiple occasions (e.g., Miyamato, 1983;Crawford 2003a;Crawford and Smith, 2005;Elmer et al, 2007;Crawford et al, 2007;Wang et al, 2008;Padial and De la Riva, 2009). However, the C. podiciferus complex is atypical when compared to previous examples in that many of the divergent lineages described herein are syntopic with one another (Fig.…”

“…Although amphibian species composition in these Isthmian mountains is relatively well known (Campbell, 1999;Savage, 2002) our understanding of the phylogeographic relationships within these species is not. Previous molecular studies on montane bolitoglossine salamanders from this region have revealed extremely high levels of genetic diversity across a relatively small geographic area (Garcia-Paris et at., 2000;Wiens et al, 2007) hinting that levels of diversity in these uplands may mirror the high genetic diversity described for lowland amphibians in the region (e.g., Crawford, 2003a;Weigt et al, 2005;Crawford et al, 2007;Wang et al, 2008). To our knowledge, no molecular study has extensively examined the intraspecific relationships of any anuran species that is restricted to the highlands of Costa Rica and western Panama, despite >20 frog and toad species sharing this distribution (Savage, 2002).…”

“…Given the frequency of cryptic lineages among Panamanian amphibians (41,42), we estimated amphibian diversity using DNA Barcode of Life protocols (18,43) to establish the number of lineages and quantify PD. We combined molecular genetic data with long-term field surveys to describe the change in abundance of each amphibian species, the change in community composition at El Copé including known and cryptic lineages, and the resulting loss of evolutionary history as measured by PD.…”

Amphibian populations around the world are experiencing unprecedented declines attributed to a chytrid fungal pathogen, Batrachochytrium dendrobatidis. Despite the severity of the crisis, quantitative analyses of the effects of the epidemic on amphibian abundance and diversity have been unavailable as a result of the lack of equivalent data collected before and following disease outbreak. We present a community-level assessment combining long-term field surveys and DNA barcode data describing changes in abundance and evolutionary diversity within the amphibian community of El Copé, Panama, following a disease epidemic and mass-mortality event. The epidemic reduced taxonomic, lineage, and phylogenetic diversity similarly. We discovered that 30 species were lost, including five undescribed species, representing 41% of total amphibian lineage diversity in El Copé. These extirpations represented 33% of the evolutionary history of amphibians within the community, and variation in the degree of population loss and decline among species was random with respect to the community phylogeny. Our approach provides a fast, economical, and informative analysis of loss in a community whether measured by species or phylogenetic diversity.amphibian decline | biodiversity | chytridiomycosis | DNA barcoding | phylogenetic diversity
