Geographic Range [top]

Range Description:This species was previously only known from Cerro Munchique on the Pacific slopes of the Cordillera Occidental, Cauca Department, Colombia. It is now also known from Vereda Santa Elena, Popayán, in the Cordillera Central, also in Cauca Department, Colombia (Colombia Red List Assessment Workshop August 2016). The elevational range is between 2,170–2,768 m asl (Duellman 1987, Guerrero-Vargas et al. 2007). Its EOO is 575 km2.

Population [top]

Population:The species was reported to be relatively common in Cerro Munchique. Surveys in the area in 2014, 2015, and 2016 failed to record the species (Colombia Red List Assessment Workshop August 2016). A second subpopulation was discovered in Vereda Santa Elena in 2005 when five individuals were found (Guerrero-Vargas et al. 2007; specimen identification verified by J. Lynch). An intensive search in this area in 2016 (three people over three nights) recorded a single individual (J. Guerrero-Vargas, unpubl. data 2016). Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs on vegetation and next to streams inside forest and at the forest edge, and seeks refuge in bromeliads. It can occur in habitat such as páramo as long as there are bromeliads, and it has also been found in a pasture next to a stream (Guerrero-Vargas et al. 2007). Breeding is by direct development, with the eggs kept in the pouch of the female until hatched.
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species been utilized.

Threats [top]

Major Threat(s): Although the species occurs within a protected area, cultivation of illegal crops is causing destruction of native habitat where the species was found in the park. Intensive spraying of glyphosate from 2002–2010 to eradicate illicit crops may also have impacted the species (Colombia Red List Assessment Workshop August 2016). In Vereda Santa Elena, the species is threatened by the establishment of eucalyptus plantations and pesticides used on these plantations (Colombia Red List Assessment Workshop August 2016).

Conservation Actions [top]

Conservation Actions: Conservation Actions
The type locality is entirely within Munchique National Park. The Vereda Santa Elena locality was declared in 2012 to be a watershed protection area (Fundación Pro-Cuenca Río Las Piedras-Empresa de Acueducto y Alcanterillado de Popayán) (Colombia Red List Assessment Workshop August 2016).

Conservation Needed
There is a need to combat activities that result in the loss of native habitat within the national park boundaries. 

Research Needed
More research is needed to better determine the range of the species and population size and trends.
