Habitat and Ecology
The species is associated to streams, where individuals can be found on rocks near streams, in shallow water, soil and leaf litter (Jordão-Nogueira et al., 2006), in primary and secondary forest. It breeds in streams.
Individuals are mostly active by day, but also exhibit some nocturnal activity. The species feeds on arthropods, with beetles, ants, dipterans and insect larvae being the predominant items. Females have been found to contain between 70-127 unpigmented vitelogenic eggs (Jordão-Nogueira et al., 2006).
Jordão-Nogueira et al. (2006) report on 37 individuals collected between late September and early October 2004.
The main threat to this species is loss of habitat as a result of clear-cutting, human settlement and tourism.
It occurs in several protected areas.
