The species is known only from the right bank of the Florestão river (22 55’ S, 44 21’ W; near sea level), Ariró, Municipality of Angra dos Reis, state of Rio de Janeiro, Brazil (Weber et al., 2006).
Habitat and Ecology
Individuals of Physalaemus angrensis were collected near sea level, associated with ponds or leaf litter from the coastal plain in the Atlantic Forest domain. They are often found under dead leaves on the edge of temporary ponds at very disturbed sites near the border of secondary forests. Males call at late afternoon during the rainy season (October to February) in this region (Weber et al., 2006).
It is possible that P. signifer (and probably also P. spiniger) occur in the same habitat. Two species of the P. signifer group are geographically close to P. angrensis: P. atlanticus and P. moreirae, known respectively from a lowland and a mountain locality in northeastern São Paulo state (Weber et al., 2006).
No population status information is available for this species.
No major threats are known for this species.
No conservation measures are known for this species.
Red List Status
Data Deficient (DD)
A member of the Physalaemus signifer group according to the original publication. The new species can be differentiated from similar species by a combination of morphological characters and advertisement call features (Weber et al., 2006).
