Habitat and Ecology
This species is believed to be an explosive breeder (E.M. Lucas pers. comm. June 2010), and it is thought to reproduce in temporary streams. It may also reproduce in temporary pools (P. Garcia pers. comm. June 2009). It is not known whether this species may occur in disturbed habitats.
There have been limited survey efforts in the area where it occurs (E.M. Lucas pers. comm. June 2010). Until recently, the last reported collection dated back to August 1965 (D. Baldo pers. comm. June 2009). In the course of monitoring activities for hydroelectric power stations, recent records for this species have emerged by way of pitfall traps in other sites along the Upper Rio Uruguai (E.M. Lucas pers. comm. June 2010). A lack of records along the higher limits (730 m asl) of the municipality of Chapecó suggests that the species may be associated with lower elevations (E.M. Lucas pers. comm. June 2010).
Populations from Misiones formerly associated to this species are believed to pertain to Melanophryniscus aff. tumifrons (Baldo and Basso 2004).
