This species occurs in the Amazon drainage basin of Colombia, Ecuador, Peru and Brazil, from the foothills of the Andes east to the mouth of the Amazon and north into eastern French Guiana, at below 400m asl.
Habitat and Ecology
This diurnal frog has been found in tropical rainforest, in epiphytes growing on trees, and in leaf-litter on the forest floor (Ron, 2001). At Lago Agrio, Ecuador, individuals have been collected on the ground in primary forest (Duellman, 1978). The eggs are laid on the ground, and the tadpoles are carried to the water in bromeliads. It has been seen 40m above the forest floor.
Its abundance varies throughout its range, it is common in Colombia while it is rare in Ecuador.
Clear cutting, forest conversion, logging, fire, human settlement and water pollution (near Belem city) are threats to this species.
Conservation units are present within its range. In Ecuador, its geographic range overlaps with Reserva Biológica Limoncocha and Parque Nacional Yasuní.
Red List Status
Least Concern (LC)
Caldwell and Myers (1990) formally revived Ranitomeya ventrimaculata from the synonomy of Adelphobates quinquevittatus, where it had been placed by Silverstone (1975), but urged caution in dealing with it systematically. They emphasized that R. ventrimaculata contains an unknown number of undiagnosed species, some of which might be difficult to separate even when sympatric, but the name serves to accommodate certain populations previously assigned to A. quinquevittatus.
