This species ranges from extreme south-eastern Chiapas, Mexico, along the Pacific versant to Volcán Atitlán, south-western Guatemala. Its altitudinal range is 1,500-2,100m asl.
Habitat and Ecology
It is an arboreal species, inhabiting pristine cloud forest habitats, and is often found in bromeliads. It breeds by direct development and is not dependent upon water.
Although it used to be common, it appears to have undergone declines and is now uncommon. It was common on Volcan Tacana in the 1970's, but no recent surveys have been made. It was rare, but still present in Departamento San Marcos in 2005.
The major threat is the loss of cloud forest due to extensive agricultural activities (including agro-industry crop farming), logging, and human settlement.
It has been recorded from the 'Quetzal Reserve' close to Finca Insula in Chiapas, Mexico (Ted Papenfuss and Sean Rovito pers. comm., 2007), and from the proposed protected area of Volcán Atitlán. Surveys are urgently needed to establish the current population status of this species. It is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat along the Pacific versant of Guatemala and Mexico.
