From the IUCN Red List Species Account:

 

Range Description

This species is only known from a small patch of forest around Tianguistengo in north-eastern Hidalgo, Mexico, between 1,900-2,100 m asl. It occurs in one threat-defined location and its extent of occurrence (EOO) and area of occupancy (AOO) is 14 km2.

Habitat and Ecology

It inhabits humid pine-oak or cloud forests, where it lives in bromeliads and reproduces by direct development.

Population

Only one individual of this species had been found by Parra-Olea et al. (1999) since the 1980s, until it was recorded again in 2010 (S. Rovito pers. comm. Red List Assessment Workshop December 2014). Due to ongoing declines in its habitat quality and extent, the population is suspected to be decreasing.

Population Trend

decreasing

Major Threats

Since this species is dependent upon bromeliads in trees, the major threat to it is deforestation and fragmentation, which is taking place at the site due to expanding agricultural development and extraction of wood. Fire is also a threat as most of the agricultural practices in the region use slash and burn methods (P. Arias Caballero pers. comm. August 2015).

Conservation Actions

Conservation Actions
This species occurs on private land and is not found in any protected areas. This species is protected by Mexican law under the "Special Protection" category (Pr).

Conservation Needed 
Protection of the forests in the Huasteca region is urgently required.

Red List Status

Critically Endangered (CR)

Rationale

Listed as Critically Endangered because its extent of occurrence (EOO) is 14 km2, it occurs in one threat-defined location and there is a continuing decline in its extent of occurrence, area of occupancy and quality and extent of its habitat.
