This species occurs in southern Amazonia, in the Rio Madeira drainage of western Brazil, although it is known definitively only from Rondônia and adjacent Amazonas, and also Iquitos, Peru.
Habitat and Ecology
It lives in the leaf-litter on the forest floor in the tropical rainforest. It lays its eggs out of the water on a leaf, and the tadpoles are carried to the seasonal water sources including bromeliads.
It is abundant.
Forest conversion, fire, logging and mining are threats to this species.
Conservation units are present within its range.
Most records of this species before 1990 refer to Dendrobates ventrimaculatus. Caldwell and Myers (1990) and Martins and Haddad (1990) independently concluded that the name Dendrobates (now Adelphobates) quinquevittatus Steindachner, 1864, had been misapplied in recent literature. It is currently restricted to a species that is neither as variable or widespread as previously thought, and which is known only from the upper Rio Madeira drainage of Rondonia and adjacent (southern) Amazonas, Brazil. In this account we follow the traditional, broader definition of the species.
