Geographic Range
This species occurs on the Guiana Shield, from Mount Roraima in Western Venezuela, to nearby Guyana (Mt Ayanganna, Mt. Wokomung, Kaieteur National Park and northern Pakaraima region), reaching to Serra do Veado, in Amapá state, Brazil. It is found between 40 and 2,200 masl.
Population
It is not a common species. It is probably locally abundant, but its secretive habits make it hard to find (R. MacCulloch pers. comm. 2009).
Habitat
This tiny diurnal frog is found in the leaf-litter on the forest floor of rainforests near streams. Often associated with formations of Monotagma spicatum, males call from the base of plants, hidden among rootlets and among dead leaves at the base of plants (MacCulloch et al. 2008). The deposition of eggs takes place at the beginning of the rainy season, and they develop directly. One female was found to deposit a single, large egg among dead leaves (MacCulloch et al. 2008).
Threats
There are no known threats to the species at present, and it occurs in a region of minimal human impact.
Red List Rationale
Listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.
