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 ). For a more detailed description see Hoogmoed & Ávila-Pires (1992) and Ávila-Pires (1995).

FIGURE 4. Distribution maps for the cis-Andean microteiid lizards in Colombia (Alopoglossidae + Gymnophthalmidae). Circles are examined specimens, while squares are records from literature (see Supplementary Files for specific references). Red arrows indicate new records for Colombia. Black arrows show a zoom in to regions where several records overlap. The light green shadow indicates the Orinoco River basin, and the dark green the Amazon River basin.
