This species was originally known from three localities in Mazaruni-Potaro District, Guyana. In his description of the species, Heyer (1975) gave the type locality of Chinapoon River (at about 300m asl) on the upper Potaro River, and a second locality as Demerara Falls (it has not been possible to map this locality in this assessment as its exact location is unknown). Additional specimens were recently collected in October 2000 at 1,500m asl on Mount Ayanaganna in the Pakaraima Mountains, also in Potaro-Mazaruni District, Guyana (MacCulloch and Lathrop 2002). Heyer (1975) suggested that the Chinapoon River in the description of the type locality probably referred to Chenapowu River. Chenapowu (also referenced as Chenapou and Chenapau) is a river and a village on the upper Potaro River. Kok et al. (2007) recently reported records from Kaieteur National Park, Mount Ayanganna, Mount Wokomung and the Merume Mountains in the Pakaraima Mountains region of Guyana.
Habitat and Ecology
It inhabits lowland and montane tropical primary forest.
It is a mostly nocturnal species, inhabiting leaf litter. Reproduction seems to be constrained to the wettest months of the year. Gravid females have been found to contain 3-10 large white eggs (Kok et al., 2007).
It may be locally common (Kok et al., 2007).
There are no known threats to this species, and it occurs in a large area of undisturbed remote forest.
The known locality in the Chinapau River area is within an indigenous reserve, affording some level of protection. It also occurs in Kaieteur National Park (Kok et al., 2007).
