This species is known only from the type locality of Río Sihuas, in the department of Ancash, in the Peruvian Andes. It was originally reported from an elevation of 2,700 m asl, but this elevation refers to the town of Sihuas and not the actual site where the species was found, which was at a higher elevation (C. Aguilar pers. comm. December 2010). The approximate elevation at the type locality is 2,940 m asl. Its distribution is very poorly known, thus it is may occur more widely.
Habitat and Ecology
This is a riparian semi-aquatic species. It has been found under rocks in a fast-flowing stream through alder forest. It is also found under rocks in pools and moist soil during dry periods. Reproduction occurs in streams. It is not known whether it occurs in degraded habitats.
There is little information on the population status of this species, yet the population is suspected to be decreasing due to ongoing decline in the quality and extent of its habitat. In 1992, the type series, consisting of 10 adult frogs, was collected from Rio Sihuas (Salas and Sinsch 1996). A survey in August 2008 did not reveal any individuals, although this survey took place at 2,800 m asl and it is not known whether this species occurs at this elevation (C. Aguilar pers. comm. December 2010).
It is possible that the species may be impacted by forest loss due to agricultural expansion. The Río Sihuas is used for the irrigation of adjacent agricultural areas. Similar to its congeners, this species is likely to be very susceptible to chytridiomycosis caused by Batrachochytrium dendrobatidis. The pathogen has yet to be reported from this species; however there are several reports of infections in congeners in southern Peru (Seimon et al. 2005, Catenazzi et al. 2011).
It is not present in any protected areas.
Habitat protection is urgently needed to ensure the maintenance of suitable habitat for this species.
Further surveys need to be undertaken to relocate this species, and additional research into its distribution, population status, natural history and threats is needed.
Red List Status
Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.
