Listed as Critically Endangered because its extent of occurrence is 40 km2, it is currently only known from one threat-defined location, and there is continuing decline in the extent and quality of its habitat and in the number of mature individuals. The population is known to be much, much smaller than some decades ago. Because of poor management of the area where it occurs, it is unclear whether this location will remain suitable in the near future.
|Previously published Red List assessments:|
|Range Description:||This species was previously known only from a cave near Durango town, in northern Hidalgo, Mexico, at 2,160 m asl. However, recently it has been found in another location nearby; both within the Parque Nacional Los Mármoles. There is no a priori reason to assume that the species is endemic from Hidalgo and more cave exploration is needed to determine its range. Its extent of occurrence (EOO) and area of occupancy (AOO) is 40 km2.|

|Population:||The population trend is unknown as this species had not been seen for 73 years. However, in 2010, this species was recorded again from a cave near the type locality. It is no longer found at the type locality, which has become uninhabitable due to pollution and dessication.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It is a crevice-dweller that apparently requires humid caverns in pine-oak forest in order to survive. It is a terrestrial species that breeds by direct development.|
|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 forest habitat surrounding the caves is under severe pressure from expanding agriculture, slash and burn agricultural methods and wood extraction. Like Chiropterotriton magnipes, this species seems to have disappeared from its type locality due to the drying of its caves following the removal of forest and from pollution - the cave is currently filled with trash.|
It is found in a cave and it could occur at other caves in Parque Nacional Los Mármoles. It is protected by Mexican law under the "Special Protection" category (Pr).
Improved management of the park is required, with special attention to the caves where this and other salamanders could occur. Ideally some caves should be put off limits given their fragility.
Research is needed on its natural history, population size and distribution. A species recovery plan needs to be developed and implemented preferably together with the park's authorities, and a monitoring program is recommended to follow population trends.
