This species is known only from central coastal Guerrero, Mexico, in north-western Acapulco city.
Habitat and Ecology
The primary habitat is xeric and deciduous forest, and it has never been recorded out of the lowlands near Acapulco. It is a stream-breeding amphibian.
It is thought to be rare.
The main threat is habitat loss due to agricultural expansion, wood extraction, and the expansion of plantations.
Protection of the suburban and tropical dry areas around Acapulco represents the only chance for the survival of this species. It is protected by Mexican law under the "Special Protection" category (Pr).
This species is currently under taxonomic review.
