This Mexican endemic is known only from the northern state of Puebla, in the vicinity of Huauchinango city and adjacent Río Necaxa.
Habitat and Ecology
The main habitat in Río Necaxa, and the surroundings of Huauchinango, is pine and pine-oak forest. This frog is highly associated with permanent river systems where it breeds.
This species has not been seen since it was first collected almost 50 years ago. Several recent field surveys in the Huauchinango area reported no individuals of this frog, and it is probably extinct.
The disappearance of these permanent rivers has contributed to its decline, and perhaps extinction, and the damming of the Nexaca River for hydroelectric power, in particular, is believed to have affected this species.
The species is not known to occur in any protected areas. An extensive search within the known range of this species is needed to determine whether or not it still survives. It is listed as "Endangered" by the Mexican government.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Extent of Occurrence is less than 100km2 and its Area Of Occupancy is less than 10km2, all individuals are only known from a single location, and there has been a continuing decline in the extent and quality of its habitat, and in the number of mature individuals, in northern Puebla.
