English Names

Distribution

Lower Amazonian slopes of Andes from Colombia (1400–2000 m elevation) to Provincia Morona Santiago, Ecuador, and 203 km to the southeast in the Cerro Kampankis area of Loreto, Peru and into Caqueá, Colombia. See comment about cryptic species. 

Comment

Almendáriz C. and Orcés, 2004, Rev. Politécnica, Quito, 25: 118, provided distributional data for Ecuador. Ron, Toral, Venegas, and Barnes, 2010, ZooKeys, 70: 67–92, provided an mtDNA which showed samples of Osteocephalus verruciger being noninclusive with respect to Osteocephalus buckleyi, suggesting either introgressive hybridization or cryptic species; they also suggested (p. 85) that records from Peru are based on misidentified Osteocephalus mimeticus. In the Osteocephalus buckleyi species group of Jungfer, Faivovich, Padial, Castroviejo-Fisher, Lyra, Berneck, Iglesias, Kok, MacCulloch, Rodrigues, Verdade, Torres-Gastello, Chaparro, Valdujo, Reichle, Moravec, Gvoždík, Gagliardi-Urrutia, Ernst, De la Riva, Means, Lima, Señaris, Wheeler, and Haddad, 2013, Zool. Scripta, 42: 351–380. Catenazzi and Venegas, 2012, in Pitman et al. (eds.), Rapid Biol. Social Invent. Rep. 24 268, provided the Peruvian record and dicussed the range. Batallas-R. and Brito, 2016, Rev. Mexicana Biodiversidad, 87: 1292–1300, reported on vocalizations from Sangay National Park, southeastern Ecuador. Chasiluisa, Caminer, Varela-Jaramillo, and Ron, 2020, Neotropical Biodiversity, 6: 21–36, noted that this nominal species is composed of four lineage-species of which the name-bearing clade is found in  Napo and Morona-Santiago, Ecuador. Presumably the other species will be named in other papers.
