From the IUCN Red List Species Account:


Range Description

This species is known from a single locality (El Pedregal Reserve) in the Southern Distrito Federal, central Mexico, in the lava fields of Volcán Xitle, in the southern part of Mexico City.

Habitat and Ecology

It inhabits dry shrubland, and breeds by direct development.


This is not a very common species and it is difficult to collect.

Population Trend


Major Threats

The extension of Mexico City has resulted in the disappearance of most of the available suitable habitat for this species, with the result that it is now believed to be restricted to a very small protected area, the Pedregal Reserve. The Pedregal has been subject to long-term disturbance (fragmentation and isolation), and is now little more than an isolated vegetation fragment of 160 ha with no natural corridors.

Conservation Actions

Survey work is urgently needed to establish the current population status of this species, subsequent to which a recovery program and strict protection of the species in the Pedregal Reserve and surroundings areas might need to be implemented. It is protected by Mexican law under the "Special Protection" category (Pr).

Red List Status

Critically Endangered (CR)


Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2 and its Area Of Occupancy is less than 10km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat south of Mexico City.

Taxonomic Notes

The taxonomic status of this species is uncertain.
