Allobates granti is currently known from French Guiana, at elevations between 100-730 masl.
Habitat and Ecology
This is a diurnal, forest-dwelling species not closely associated with bodies of water. Males are territorial and call from the leaf litter. Reproduction does not seem to be seasonally constrained, as courtship and tadpoles were observed in February and March, and females collected in February, April, May July and November contained mature eggs. An egg clutch was found to have 9 fertile eggs (Kok et al., 2006).
This is considered to be an uncommon species, and found in small isolated populations at Arataye and Nouragues, French Guiana (Kok et al., 2006).
There are no major threats known for this species.
Most of the species' distribution lies within the “Amazonian Park” of French Guiana. However, there are problems with illegal mining and associated pollution in the park (P. Kok, pers. comm. 2008).
Allobates granti can be distinguished from other congeners by a combination of morphological, bioacoustical and behavioural features (Kok et al. 2006).
