From the IUCN Red List Species Account:

 

Range Description

This species is found in xeric environments of north-western Peru (Departamento Tumbes) and the Gulf of Guayaquil, Ecuador (Guayas and Manabi Provinces). Two subspecies are recognized: C. s. scaphiopeza in Ecuador, and C. s. stolzmanni in Peru. It has an altitudinal range of 0-100m asl.

Habitat and Ecology

The habitat where some individuals have been collected can be described as tropical scrub, which is usually fairly open with a few trees, but remains green for about half the year. Other specimens have been collected in an open and sandy desert, with scattered, low, desert vegetation, and trees that are absent except in or near temporary streambeds (Peters 1967). It lives below ground when not breeding, but is an explosive breeder during good rains (with breeding taking place in water).

Population

It is a very rare species, but has been recorded in the last few years in Ecuador. There is no information on its population status in Peru.

Population Trend

Decreasing

Major Threats

The major threat is habitat loss due to agriculture (especially cattle ranching), logging, and human settlement. Soil pollution, due to agrochemicals, also represents a threat.

Conservation Actions

It occurs in Parque Nacional Machililla and Reserva Ecológica Manglares Churute in Ecuador, and the Zona Reservada de Tumbes in Peru. Further survey work is needed to determine the population status of this species in Peru.
