Diago-Toro, María F., García-Cobos, Daniela, Brigante-Luna, Giovanni D. & Vásquez-Restrepo, Juan D., 2021, Fantastic lizards and where to find them: cis-Andean microteiids (Squamata: Alopoglossidae & Gymnophthalmidae) from the Colombian Orinoquia and Amazonia, Zootaxa 5067 (3), pp. 377-400 : 384

Bachia gr. flavescens

Distribution: Widespread in the Amazonian region of Brazil, French Guiana, Suriname and Guyana (Ribeiro-Júnior & Amaral 2017). In Colombia there are some records in the eastern Amazonia region, in the departments of Guaviare and Vaupés ( Fig. 4B ).

Similar species: Bachia flavescens may be differentiated from other cis-Andean species of the B. heteropa group ( B. alleni , B. guianensis , B. heteropa , B. pallidiceps , B. trinitatis ) and B. bresslaui group ( B. bresslaui , B. cacerensis , B. panoplia , B. psamophila , B. pyburni , and B. scolecoides ) in having quadrangular dorsal scales (hexagonal to lanceolate in B. bresslaui and B. heteropa groups). See Dixon (1973), Ávila-Pires (1995), and Ribeiro-Júnior et al. (2016) for a detailed description and comparisons.

Remarks: Bachia flavescens has been suggested as a species complex given its broad morphological variation ( Kizirian & McDiarmid 1998; Ribeiro-Júnior & Amaral 2017). Previously, Dixon (1973) suggested that the individuals from Colombia belonging to the B. flavescens group may correspond to an undescribed species.

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.
