A new small golden frog of the genus Pristimantis (Anura: Craugastoridae) from an Andean cloud forest of Colombia

Abstract: A new species ofPristimantisis described from an Andean cloud forest at 2650 m in the Cordillera Oriental of Colombia.Pristimantis doradosp. nov. is similar to and could be closely related toP. acutirostris, but can be readily distinguished from this latter species by the absence of a tympanic annulus, vocal slits, vocal sac and reticulations on concealed surfaces, and by having a metallic gold iris with a brown horizontal streak. The phylogenetic position of the new species is recovered and we provide its adv… Show more

“…In the last decade, 155 new species of Pristimantis have been described for South America, mainly from the Andean regions of Peru, Colombia, Ecuador and the Guianas Shield. The heterogeneity in the topography of the Andes, accompanied by the life history of Pristimantis (direct development, high endemism and ability to colonize various habitats, including high altitudes) could be partly responsible for this notorious biodiversity [4]. The regions with the most homogeneous topography (Amazon Basin) present a high number of species that undergo a process called morphological stasis [16], where species that suffer strong selection by the environment or physiological characters for adaptation in a specific habitat, may not present morphological changes between species [63].…”

“…Most species of this genus occur in the western part of the Amazon [3]. The topographic heterogeneity of the Andes, accompanied by the life history of Pristimantis (direct development, high endemism and the ability to colonize a wide variety of habitat types, including highlands) could be partially responsible for this great diversity [4]. In the eastern Amazon, few studies have focused on taxonomic aspects of Pristimantis populations, and most of the information about this genus comes from faunal inventories [5][6][7][8], of which many do not present specific identification of existing lineages [9].…”

“…No obstante, sólo 18 especies (el 6.8%) han sido evaluadas acústicamente. Los estudios en Colombia que incluyen análisis de señales acústicas en especies de esta familia se han centrado en describir sus cantos de anuncio (Bernal et al, 2004;Romero-García et al, 2015; Ríos-Soto y Ospina-L. 2018; Duarte-Marín & Arango-Ospina, 2019) o en utilizar atributos de dichas señales como evidencia en la delimitación de nuevas especies (Ospina-Sarria et al, 2015;Rivera-Correa et al, 2016;Ospina-Sarria & Angarita-Sierra, 2020). El 72% de las investigaciones en señales acústicas de los anuros de Colombia se ha desarrollado en especies con distribución andina.…”

“…), patrón también registrado por Bernal & Lynch (2008). Esto podría ser causado porque todavía es una cordillera poco explorada, ya que aún existen áreas con bajo esfuerzo de muestreo en relación con las unidades fisiográficas vecinas, o carece de inventarios sistemáticos; muestra de ello son las recientes descripciones de nuevas especies en distintas zonas de esta cordillera, como en la Sierra de Perijá (p.e., Barrio-Amorós et al, 2008, Infante-Rivero et al, 2008, Barrio-Amorós et al, 2010, Rojas-Runjaic et al, 2011, en la Sierra del Cocuy en el departamento de Boyacá (Guarnizo et al, 2012), en las montañas del departamento de Nariño (Mueses-Cisneros et al, 2013) y parte central de esta cordillera (Rivera-Correa et al, 2016). A esto se puede sumar el hecho de que ésta es una cadena montañosa geológicamente joven en relación con las otras cordilleras colombianas y ecuatorianas, por lo FIGURA 2: Número de especies, endemismo y porcentaje de endemismo de anuros en las unidades fisiográficas del norte de los Andes.…”
