Alopoglossus buckleyi (O’Shaughnessy, 1881) Distribution: Western Amazonia in Brazil, Peru, Ecuador and Colombia (Ribeiro-Júnior & Amaral 2017). In Colombia along the southern Amazonian region, in the departments of Putumayo, Caquetá, Vaupés and Amazonas (Fig. 4A). Similar species: Alopoglossus buckleyi can be differentiated from other similar species due to the lack of occipital scales (present in A. bicolor and A. brevifrontalis); in having small granular scales on the sides of the neck, similar in shape to those near the tympanic aperture (non-granular, keeled and imbricated resembling those in the dorse in A. avilapiresae and A. carinicaudatus); and for possessing smooth ventral scales (strongly or weakly keeled in A. atriventris). For a more detailed description see Ribeiro-Júnior et al. (2020).
