This species is listed as Least Concern because of its occurrence in a number of protected areas, and because it is unlikely to be declining at nearly the rate required to qualify for listing it in a threatened category.

Geographic Range [top]

Range Description:The species is known from the central forests (i.e., distant from the coasts) of Panamá, from the Darién throughout central Panamá to Bocas del Toro and Chiriquít, from ca. 400 to 1.500 m. Although there is no verified record for this species in Colombia (Gardner and Creighton 2008, Solari et al. 2013), given its distribution in Panama it could actually occur in there (see Cuartas Calle and Arango 2003).

Habitat and Ecology [top]

Habitat and Ecology:This species is found in mid-elevation dense evergreen forests, primary and second growth, between 400 and 1.500 m (Emmons and Feer 1997, Reid 2009). It inhabits the jungle understory in very humid habitats, and is frequently found in fallen trees, on the ground in moist areas or among rocks, apparently being more terrestrial than other co-generic species (Pine 1981). It is occasionally caught on logs up to 2 m above ground. The diet includes insects and plant material. Little is known of its ecology, a lactating female was noted in March (Reid 2009).

Threats [top]

Major Threat(s): No major threats exist for this species. Despite this, its limited range within forested environments could change its conservation status rather quickly, especially if the protected areas where the species has been recorded/trapped are deforested.

Conservation Actions [top]

Conservation Actions: The species is found in several protected areas in Panamá (e.g., Darién National Park, Chagres National Park, and Fortuna forest reserve).

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
