In Colombia, the de Santa Marta in Colombian Andes (Santander, Norte Andes Mountains are divided into three major mountain de Santander, and La Guajira departments) between ranges: Cordillera Occidental, Cordillera Central, and August 2012 and April 2016 resulted in the finding of Cordillera Oriental; with the later harbouring the lower unreported populations of eight anuran species belonging anuran diversity (155 species; 21% of the national to five families: Aromobatidae (1 species), Bufonidae anuran diversity; Acosta-Galvis, 2017) but the higher (1 species), Centrolenidae (1 species), Craugastoridae level of endemism (77 species; ca. 50%; Lynch et al., (4 species), and Dendrobatidae (1 species). Specimens 1997; Bernal and Lynch, 2008; Armesto and Señaris, were identified based on the original species descriptions 2017). While most anuran species from the Cordillera (Günther, 1869 “1868”; Lynch and Duellman, 1973; Oriental of Colombia have been described just over Lynch, 1984, 1996; Kaplan, 1997; Barrio-Amorós et the last 50 years, mainly thanks to the taxonomic work al., 2007; Anganoy-Criollo, 2012; Ospina-Sarria et by J.D. Lynch, P.M. Ruiz Carranza, and M.C. Ardila al., 2015). Voucher specimens were deposited in the Robayo, the recent discovery of new species (e.g., herpetological collection of Universidad Industrial de Anganoy-Criollo, 2012; Acosta-Galvis, 2015; Ospina- Santander (UIS-A) and herpetological collection of Sarria et al., 2015; Rivera-Correa et al., 2016; Rojas- Universidad de Pamplona (MCNUP-H). We provide Runjaic et al., 2018) and the report of new localities for updated distributional maps for the reported species described ones (e.g., Duarte-Cubides and Cala-Rosas, based on relevant literature and specimens housed at 2012; Acevedo et al., 2014; Meza-Joya, 2016), suggest herpetological collections. Records containing uncertain that additional surveys in poorly known areas of this or inconsistent geographic information were excluded cordillera and the careful examination of specimens from the maps. Collection acronyms followed Frost (2017).

During fieldwork, combination of the following characteristics (Anganoy- from 13:00 to 17:00 h, we recorded one female, six Criollo, 2012): (1) disks on finger III and toe IV, males, five tadpoles, and two metamorphic specimens. slightly expanded; (2) faintly differentiated lateral keels Males were found calling under rocks in the margins of on all fingers; (3) fringes on all toes, slightly expanded; the river, suggesting reproductive activity.

In Colombia, R. glaberrimus (7) gular-chest region cream, sexually dimorphic; with has been registered from several localities on the scarce brown stippling in adult females and uniformly eastern piedmont of the Cordillera Oriental in Boyacá, dark, brown to greyish brown, in adult males; (8) cloacal Casanare, Cundinamarca, and Meta departments, tubercles absent; and (9) pattern of coloration on dorsum between 520 and 1470 m elevation (Lynch, 2006; brown to dark brown, with one diffuse wide band from Mueses-Cisneros et al., 2012; but see Ruiz-Carranza et snout to urostyle. We consider that variation in the al., 1996). The type locality of this species (i.e., “, dorsolateral and oblique lateral stripes in the specimens Cundinamarca”) is probably in error because Bogotá city and its surroundings are about 1100 m above the upper altitudinal limit of the species (1470 m a.s.l.), this region harbour habitats very different of those where the species occurs, and herpetological surveys in this region has not been recorded the species (Mueses-Cisneros et al., 2012). Likewise, the record from (Puerto Rastrojo, Mirití-Paraná river; IAvH 2502) reported by Acosta-Galvis (2017) was assigned to Rhaebo guttatus by Mueses-Cisneros et al. (2012) based on the morphological examination of the specimen. The specimens reported here (MCNUP-H 0423, 0433, 0441) comes from three sites along an elevational gradient at vereda San Antonio, San Lorenzo river, Toledo municipality, Parque Nacional Natural Tamá, Norte de Santander department, Colombia (7.1604°N, 72.2286°W, 646 m a.s.l.; 7.1503°N, 72.2218°W, 780 m a.s.l.).

Here we report this species from San Lorenzo river, vereda San Antonio, National Natural Park Tamá, Toledo municipality, Norte de Santander department, Colombia (7.1569°N, 72.2125°W, 714 m a.s.l; 7.1572°N, 72.2231°W, 829 m a.s.l). Collected specimens (MCNUP-H 0231, 0233) account for the first records of R. flavopunctata at foothills of Tamá Massif in Colombia and extends its distributional range ca. 224 km NNE from the closest known record (La Limonita stream, Pajarito municipality, Boyacá department; Fig. 3). Figure 2.

Individuals were recorded between 14:00 and 17:00 h, over rocks and on the base of shrubs (Miconia sp.) at the margins of San Lorenzo river. Vegetation at the study site corresponds to riparian Sub-Andean forest associated with large cattle grazing areas.

We consider that colour differences in the specimens reported here (see above) are probable due to intraspecific variation. However, further studies (morphological, acoustic, and genetic) should be conducted for this widely-distributed and highly-variable taxon as cryptic diversity may occur (Cisneros-Heredia, 2009). Some adult males were found calling from stones and perching on leaves (Cyclanthaceae) at heights until 3 m, indicating reproductive activity. Vegetation at the study site corresponds to riparian Sub-Andean forest associated with large cattle grazing areas. Figure 4.

This species is currently considered part of the Bernal and Lynch, 2008). Most of the specimens newly recognized “Colostethus” ruthveni group, a reported herein (UIS-A 6020 – 6022, MCNUP-H 0125 clade more closely related to all dendrobatines, except – 0126) come from three paramo zones on both flanks of Cordillera Oriental in Colombia. Two sites from an elevation gradient on the western flank at paramo de Berlín, vereda Esparta, Santa Bárbara municipality, Santander department (7.0330°N, 72.8878°W, 3001 m a.s.l.; 7.0353°N, 72.8862°W, 3112 m a.s.l.), and two paramos on the eastern flank at Parque Nacional Natural Tamá: (i) paramo La Cabrera, vereda El Molino, Herrán municipality, Norte Santander department (7.4364°N, 72.4672°W, 2980 m a.s.l.) and (ii) paramo del Tamá, vereda Siberia, Herrán municipality, Norte Santander department (7.3962°N, 72.4267°W, 3109 m a.s.l.). These specimens account for the first records of this species for páramo habitat and extend its upper distributional range from 2670 (Bernal and Lynch, 2008) to 3112 m elevation.

This group is composed of two species inhabiting the SNSM: “Colostethus” ruthveni and “Colostethus” sp. ruthveni-like, an undescribed species that strongly resembles “C.” ruthveni (Grant et al., 2017).

Colostethus ruthveni differs from other members and poorly known. This region is located near to the of this genus by the combination of the following international border with Venezuela, sharing with this characters (Kaplan, 1997): (1) narrow dorsolateral pale country a series of massifs and mountain ranges that stripe present; (2) upper part of flank dark stripe-like; represents an ecological and geological continuum (3) oblique lateral stripe, throat collar, chest spots, (e.g., Serranía or Sierra de Perijá and Tamá Massif), absent; (4) basal webbing on feet, absent on hands; thus, anuran species previously thought to be restricted and (5) expanded finger and toe discs.
