Date Assessed: 2012-05-06
Assessor(s): Campbell, J.A. & Muñoz-Alonso, A.

Geographic Range [top]

Range Description:This species is present in southwestern Guatemala and southeastern Chiapas, Mexico. In Guatemala, it is known only from two localities on the Pacific versant near San Marcos. In Mexico, this species is known only from Volcan Tacana. It is found at elevations between 1,950 and 2,630 meters.

Population [top]

Population: Owing to the species' arboreal habits, it is difficult to determine its abundance. The species was recorded in Mexico during 2004.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species is present within cloud forest and is also found close to the pine-cypress zone. It is an arboreal species, and populations require forest with mature, tall trees. It is unlikely that this species can occur in heavily deforested habitat. The species is known to persist, where tall trees remain, in areas used by indigenous peoples to produce shade-grown coffee.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): There has been large-scale deforestation within the species' range, generally through the conversion of land to agricultural use. Populations can, however, persist where large trees remain.

Conservation Actions [top]

Conservation Actions: These lizards have been found within the protected areas of Volcan Tacana Biosphere Reserve. This species is protected by Mexican law under the category Pr (Special Protection); it is not protected in Guatemala. This species would benefit from habitat protection and management, and better information is needed on distribution, abundance, population trend, life history, and threats.
