“…These islands may have allowed colonization of the Darié n from the north or south in advance of the completion of the land bridge in the Pliocene (Wang et al, 2008;Weigt et al, 2005). The increasing number of known Darié n endemic species of amphibians (e.g., Ibáñ ez and Crawford, 2004) and reptiles (e.g., Myers, 2003) supports the hypothesized old age of the fauna of eastern Panama.…”

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.

“…). Moreover, the 11 amphibian species endemic to EP (Ibáñez & Crawford, ; Crawford, Ryan & Jaramillo, ; Crawford, Lips & Bermingham, ; Batista et al ., ; this paper) support the hypothesis of EP being a centre of endemism rather than just a pathway between two continents during the Great American Biotic Interchange (GABI; Crawford et al ., ,b).…”

An integrative approach to reveal speciation and species richness in the genusDiasporus(Amphibia: Anura: Eleutherodactylidae) in eastern Panama

et al. 2016

We have applied an integrative taxonomic approach, including bioacoustics, ecology, morphology, and molecular genetics (barcoding and phylogeography), to explore species richness in the genus Diasporus in eastern Panama, from where only Diasporus quidditus (Lynch, 2001) was previously known. During fieldwork in eastern Panama in 2011 and 2012 we found six additional species, four of which we are describing here as new to science, plus two species that are new for this region. We have evaluated the presence of Diasporus diastema (Cope, 1875) in eastern Panama by comparing morphological, genetic, and bioacoustic characters of specimens from near the type locality in central Panama with specimens from eastern Panama. We further describe and compare male advertisement calls of most Diasporus species. The phylogeographic analysis suggests the allopatric speciation of Diasporus species in eastern Panama following the completion of the Panamanian isthmus in the middle Miocene. Subsequent geological events concur with the vicariant evolution of different lineages in situ, suggesting eastern Panama to be a centre of endemism for this group of frogs. We present an integrative analysis of the species from eastern Panama and include an identification key for all species of the genus.

“…Our molecular data suggest that this toe character, one of the few morphological characters available to build our taxonomy of Pristimantis and other eleutherodactyline frogs, may be subject to more homoplasy than previously thought. Some of the conflict between traditional taxonomy and our phylogeny we can relieve by recognizing the P. pardalis species group as distinct from the P. cruentus group (Ibáñez and Crawford, 2004). However, the P. cruentus group is still not a monophyletic group unless at least three strictly South American species are included (Heinicke et al 2007).…”

“…Research on New World fossil mammals from the Pliocene and Pleistocene has made famous the role of the Isthmus of Central America as a land bridge and a driver of expansion, extinction, and diversification of lineages moving between continents (Marshall et al, 1982;Simpson, 1940;Webb and Rancy, 1996). However, mounting evidence suggests that isthmian Central America itself has a rich biotic history and hosts many endemic species (e.g., Bermingham and Martin, 1998;Ibáñez and Crawford, 2004;Myers, 2003;Smith and Bermingham, 2005;Reeves and Bermingham, 2006). Even at the intraspecific level, widespread Neotropical plants and animals may harbor more genetic diversity within Panama alone than within much larger continental areas (e.g., Dick et al, 2003;Weigt et al, 2005).…”
