Abstract

We report the first record of the direct-developing frog Pristimantis museosus (Anura: Strabomantidae) in Costa Rica. We found an adult female near the Costa Rica-Panamá border in Alto Urén, Caribbean slope of Talamanca Mountain Range. This specimen agrees morphologically and phylogenetically with other P. museosus, including the type series. Pristimantis museosus is formed by two subclades, separated by genetic distances of 3.2 % in 16S and 7.1 % in cytochrome oxidase I (COI); the specimen from Costa Rica is grouped within the subclade including those specimens from eastern Panamá, nearest to type locality. Also, we found that other species in the P. ridens Species Group have a high-level of genetic variation with genetic distances reaching up to 14.5 % in 16S and 19.1 % in COI under current taxonomy. This may mask cryptic lineages under the currently recognized taxa.
