From the IUCN Red List Species Account:


Range Description

This species is known only from the type locality, Sao Lorenco do Sul, in the state of Rio Grande do Sul, Brazil, at approximately 50m asl.

Habitat and Ecology

It occurs in a seasonally inundated habitat, in which its breeding habits are unknown, though it presumably breeds in water by larval development, like other species of its genus.


Its population status is unknown. It is known from only two specimens, which were collected in 1905. Because it was only recently removed from synonymy there have been few recent attempts to locate the species, which might explain the lack of recent records.

Population Trend


Major Threats

Rice farming is possibly a threat to its habitat.

Conservation Actions

Research to determine the current status of this species is needed. It does not occur in any protected areas.

Red List Status

Data Deficient (DD)


Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.

Taxonomic Notes

The species was revalidated by Caramaschi and Cruz (2002).
