Loxopholis percarinatum ( Müller, 1923)

Distribution: In the Amazonia of Bolivia, Peru, Brazil, Colombia, Venezuela, Suriname, and Guyana (Ribeiro-Júnior & Amaral 2017). In Colombia there are records from Guaviare, Caquetá and Vaupés departments ( Fig. 4D ).

Similar species: Loxopholis percarinatum is different from other sympatric and similar species of the genus in Colombia in having an upper dark stripe on the flanks 1–3 scales wide (flanks completely covered by a wide dark band in L. parietalis and L. snethlageae ); sharply keeled ventral scales (smooth or weakly keeled in L. caparensis , smooth in L. hexalepis ); fourth pair of chin-shield reduced (not reduced in L. parietalis and L. snethlageae ); and second and third supraocular subequal and larger than the others (third supraocular larger than the second in L. snethlageae ). For a more detailed description see Ávila-Pires (1995).

Remarks: In this work, we extend the known distribution of L. percarinatum in Colombia to the municipality of Acacias, Meta department, ca. 175 km NW from its most northern previous record in San José del Guaviare, Guaviare.

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.
