Arthrosaura reticulata (O’Shaughnessy, 1881)

Distribution: Widespread along the Amazonia in Brazil, Suriname, Guyana, Peru, Ecuador, and Colombia (Ribeiro-Júnior & Amaral 2017). In Colombia in the south and eastern Amazonia region, including Putumayo, Caquetá, Amazonas, Vaupés and Guainía departments (Fig. 4D).

Similar species: Arthrosaura . reticulata can be misidentified with sympatric cis-Andean species from the genera Loxopholis and Alopoglossus . However, it is easily distinguished from the former as the posterior margin of the interparietal and parietals scales form a straight line (posterior margin of interparietal and parietals rounded in Loxopholis). In addition, it differs from species of Alopoglossus by the presence of occipital scales (absent in Al. atriventris, Al. avilapiresae, and Al. buckleyi); prefrontal scales present (absent in Al. bicolor); four pairs of chinshields, three supraocular scales, and sharply keeled dorsals (three pairs of chin-shields, four supraoculars, and weakly keeled dorsals in Al. brevifrontalis).
