Altitudinal range. Precise localities are in the range 350-1150 m.
Ecology. Recorded from Magdalena Valley and Cordillera Oriental montane forests ecoregions. The species occurs in arid habitats among species of Lippia (Verbenaceae), Stenocereus (Cactaceae) and Prosopis (Fabaceae).
Remarks. The colouration and shape of this species is somewhat variable. Within a single population, specimens may show interruptions in the colour bands to different degrees; within the same region specimens may also vary in shell elongation. In contrast, the sculpture of (slightly) oblique axial elements appears to be constant within the material studied.
