Scientific Name:

Pseudoeurycea tenchalli

Species Authority:

Adler, 1996

Common Name/s:

Spanish

–

Tlaconete Con Barba

Assessment Information [top]

Red List Category & Criteria:

Endangered A2ac+4ac ver 3.1

Year Published:

2008

Assessor/s:

Gabriela Parra-Olea, David Wake, James Hanken

Reviewer/s:

Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)

Justification:
Listed as Endangered, because recent population reductions of greater than 50% have been experienced and these declines are expected to continue. All individuals are known from a single location (presumed to be slightly greater than 100km2), which is being reduced in size and quality. The species has become very hard to locate. Increased information may in fact demonstrate Critically Endangered as a more appropriate listing.

History:

Population [top]

Population:	There is little information; it is known from very few collecting events. Last recorded in 2000 (T. Papenfuss, M. García-París, G. Parra-Olea, pers. comm., 2007). There is suspected to have been a significant decline in this species.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It lives in pine-oak forests, and is terrestrial, hiding in logs and other debris. Reproduction is by direct development.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	Although it lives in a remote area, logging has apparently been taking place on Cerro Teotepec, and this might constitute a threat to it. There is also pressure on this species' habitat from expanding small-scale agriculture.
