Fifty years after: A taxonomic revision of the amphibian species from the Ecuadorian biodiversity hotspot Abra de Zamora, with description of two new Pristimantis species

‘‘Eleutherodactylus” flavomaculatus: Heinicke, Duellman, and Hedges, 2007 Lynchius flavomaculatus: Hedges, Duellman, and Heinicke, 2008 Common English name. Yellow-spotted Andes Frog Common Spanish name. Rana andina de manchas amarillas Etymology. The specific name is derived from the Latin adjective flavus, meaning “yellow” and the Latin noun maculatus, meaning “spots” and refers to the yellow spots on the venter [25]. Fig 3. Maximum likelihood phylogram of the Lynchius species based on 2925 base pairs of concatenated DNA from 12S, 16S, and RAG-1 gene fragments. Bootstrap values (%) and Bayesian posterior probabilities (decimal) are shown except when they are below 50 (bootstrap) or 0.5 (posterior probability); asterisks indicate support values of 100% or 1 (posterior probabilities). Outgroup is not shown; the tree was routed with Strabomantis anomalus. With green are marked the newly generated sequences for the present study. The collection number, species name, province and short locality name (for the Ecuadorian samples) or country (for the Peruvian samples) of the samples are shown next to each terminal (associated data listed in S2 Table). https://doi.org/10.1371/journal.pone.0238306.g003 Fig 4.
