This species from southern and eastern Brazil ranges from the southern part of the State of Paraná, north to the State of Bahia, inland to the eastern part of the State of Minas Gerais. It occurs up to 1,100m asl.
Habitat and Ecology
It is found in rocky areas in forest, above forest, or near forest, living on wet rock walls near streams or waterfalls. The egg clutch is deposited in rock fissures. The tadpoles have been found on wet rock walls where water drains. The species feeds mostly on invertebrates, especially ants, beetles, grasshoppers, caterpillars, and spiders (Siqueira et al., 2006).
It is a common species. It was once common in Estação Biológica de Boracéia, but has not been recorded there since 1979 and is now considered to be locally Extinct (Eterovick, et al., 2005). This appears however to be a very localized decline and it is still found in the rest of the state as well as in other states.
Major threats are probably related to habitat loss due to clear-cutting, human settlement, tourism and dams. In addition, this species has tested positive for Batrachochytrium dendrobatidis (Carnaval et al., 2006).
It occurs in many protected areas. In view of the declines observed in some of the species of Thoropa in southeastern Brazil and the confirmed presence of the chytrid fungus in this species, populations should be monitored for possible declines.
