Treatment

Bachia heteropa lineata ( Boulenger, 1903)

Distribution: Probably along the east face of the Cordillera de Los Andes and adjacent foothill in west Venezuela, southward Colombia. In Colombia there is a record from the northern Orinoquia in the Arauca department ( Fig. 4B View FIGURE 4 ).

Similar species: This species can be differentiated from the Bachia flavescens species group in having hexagonal to lanceolate dorsal scales (quadrangular in B. flavescens group), and from those species in the B. bresslaui group by the presence of smooth dorsal scales (keeled in B. bresslaui species). Within the B. heteropa group it can be diagnosed in having two digits on the hindlimbs (normally four in B. alleni and B. trinitatis , and three in B. h. heteropa ); for possessing interparietal scale (absent in B. guianensis and B. remota ); and in having seven rows of gular scales (five in B. h. marcelae). For a detailed description and additional information see Dixon (1973) and Murphy et al. (2019).

Remarks: Here we are treating it as subspecies since we consider its erection to a specific level is not-conclusive (see Discussion section). Some phylogenies have suggested groups within Bachia are non-monophyletic ( Galis et al. 2010; Kohlsdorf et al. 2010), but here we are using them for practical identification purposes. Furthermore, this specimen corresponds to the first report of the subspecies for Colombia.
