Kingdom Phylum Class Order Family

Scientific Name: Ptychohyla euthysanota
Species Authority: (Kellogg, 1928)

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2010
Date Assessed: 2009-01-06
Assessor(s): Georgina Santos-Barrera, Manuel Acevedo, Antonio Muñoz Alonso
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Near Threatened because its Extent of Occurrence is probably not much greater than 20,000km2, and the extent and quality of its habitat are declining, thus making the species close to qualifying for Vulnerable.
2004 Near Threatened

Geographic Range [top]

Range Description: This species ranges from south-eastern Oaxaca, Mexico, southward to Guatemala and eastern El Salvador (from 500-2200m asl). It probably occurs more widely than current records suggest.

Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: The subspecies Ptychohyla euthysanota euthysanota lives in cloud forests while the other subspecies (P. e. macrotympanum) lives in broadleaf forests and pine forests. Both subspecies are highly associated with mountain streams. Reproduction occurs by direct development.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): A major threat to this species is alteration of the original habitats and microhabitats due to smallholder agricultural activity and logging. Chytridiomycosis is also a potential threat to this species, particularly for high-altitude populations. Declines due to chytridiomycosis amongst species of this genus have already been detected in Guatemala (Mendelson, et al. 2004).

Conservation Actions [top]

Conservation Actions: It occurs in at least two Biosphere Reserves in Chiapas (La Sepultura and El Triunfo) and is listed as "threatened" (Amenazada) by the Mexican government, although improved protection of forest habitats in southern Mexico is needed. It also occurs in Parque Nacional Montecristo in El Salvador, but is not protected in Guatemala. Given the potential threat of chytridiomycosis populations of this species should be monitored closely.
