RESUMEN
Colombia is the country with the highest bird diversity in the world. Despite active research in ornithology, compelling morphological information of most bird species is still sparse. However, morphological information is the baseline to understand how species respond to environmental variation and how ecosystems respond to species loss. As part of a national initiative, the Instituto Alexander von Humboldt in collaboration with 12 Colombian institutions and seven biological collections, measured up to 15 morphological traits of 9,892 individuals corresponding to 606 species: 3,492 from individuals captured in field and 6,400 from museum specimens. Species measured are mainly distributed in high Andean forest, páramo, and wetland ecosystems. Seven ornithological collections in Colombia and 18 páramo complexes throughout Colombia were visited from 2013 to 2015. The morphological traits involved measurements from bill (total and exposed culmen, bill width and depth), wing (length, area, wingspan, and the distance between longest primary and longest secondary), tail (length and shape), tarsus (length), hallux (length and claw hallux), and mass. The number of measured specimens per species was variable, ranging from 1 to 321 individuals with a median of four individuals per species. Overall, this database gathered morphological information for >30% of Colombian bird diversity.

We describe two new species of the genus Pristimantis from the western margin of the Eastern Cordillera of Colombia. The species have a sympatric distribution and are found in the humid tropical forests of the lower part of the Tamá National Natural Park (PNN Tamá) and its buffer zone. The new species were described from morphological comparisons and phylogenetic reconstruction from the sequencing of three mitochondrial and two nuclear genes. With these two new species, the number of Pristimantis species known in the department of Norte de Santander has increased to 10. In addition, we included new sequences for the species P. anolirex, P. nicefori, P. mondolfii, and P. yukpa. Our explorations in the last decade indicate that there are probably between five and 10 species that have not been described in the northeastern part of Colombia, especially in areas where the armed conflict has predominated in the last five decades.

The Neotropical genus Allobates Zimmerman Zimmerman (1988) is a large monophyletic clade composed of 54 described species distributed between Central America and South America (Frost, 2019; Grant et al., 2017). Twelve species have been recorded in Colombia, mostly distributed in the eastern flank of the Eastern Cordillera and Amazonian Region, although some species reach the Magdalena Valley and the Central and Western Cordillera (Acosta-Galvis, 2017).
