This species is known from the south of Bahia State, southwards through Espirito Santo State and into Rio de Janeiro State, in southeastern Brazil. It occurs up to only about 100m asl.
Habitat and Ecology
This species is found only on floating vegetation in swamps (deep water >50cm) in open areas. The eggs are deposited on a leaf surface above the water. They can also live in disturbed habitats that have deep pools of water, such as cattle ponds.
It is a very common species.
Habitat loss due to the drainage of wetlands for the creation of agricultural land, and pollution from agriculture are threats to the species.
The range of the species includes several protected areas. More research into the species' Extent of Occurrence is needed.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
