Listed as Critically Endangered (Possibly Extinct) on the basis that this species is known from a single inter-Andean valley which has been almost wholly converted for agricultural use; if it survives at all, it is in small habitat fragments under continuing pressure from this activity and from predation by several invasive species. This species is perhaps the lizard that is closest to extinction in Ecuador; as several surveys have failed to record it over the past 55 years, it is possible that it is already extinct.
This species is endemic to Ecuador where is is known only from the region of Santa Isabel, Azuay Province (Peters 1964). The elevational range is from 1250-1700 m asl. This is the only member of the genus that is known from inter-Andean valleys.
This species is known from seven specimens collected in 1959 (Peters 1964). Since then, the region has been completely transformed. The species has not been recorded again, despite several extensive efforts to collect herpetofauna in the area of the original collection. These efforts used pitfall traps, which are usually effective for this kind of lizard (J. Brito. pers. comm. 2016).
