Listed as Critically Endangered because its extent of occurrence (EOO) is 93 km2, it occurs in one threat-defined location and there is continuing decline in the extent and quality of its habitat in northern Oaxaca, Mexico.
|Previously published Red List assessments:|
|Range Description:||This species is only known from one threat-defined location of the northern slopes of the Sierra de Juarez, northern Oaxaca, Mexico, between 730-1,500 m asl (Lamoreux et al. 2015). Its extent of occurrence (EOO) and area of occupancy are 93 km2.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is very poorly known and only a few specimens have ever been recorded, despite much fieldwork having been carried out in its range. However, due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It lives in cloud forest, where it is terrestrial and fossorial, and does not survive in seriously disturbed habitats. It breeds by direct development and is not dependent upon water.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||The main threats are habitat loss due to logging, human settlement and expanding agriculture.|
It does not occur in any protected areas.
Habitat protection a priority to ensure the long-term survival of this species.
Further survey work is needed to determine its current population and taxonomic status.
