Population [top]

Population:It is known only from five specimens collected in 1989, which constitute the type series (Duellman 2004). No population information is available for this species at there are no known recent surveys for this frog.
Current Population Trend:Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:Individuals were found in small, rocky streams near or within cultivated land (Duellman 2004). Frogs were active in the streams by day (Duellman 2004). It presumably breeds by larval development.
Systems:Terrestrial; Freshwater
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no reports of this species being utilized. However, Peruvian species of Hyloxalus, in common with other poison dart frogs, may be at risk from smuggling to support the international pet trade (von May et al. 2008).

Threats [top]

Major Threat(s): This species is only known from a tiny area, but there is no information on major threats. The fungal disease chytridiomycosis was first reported from Peru in 1998 (Lips et al. 2008), and has been associated with severe declines and extinctions among Andean amphibians, especially of high-elevation, stream-breeding frogs with small ranges (Whittaker and Vredenburg 2010). It is, however, unknown whether this disease represents a specific threat to this species. This species is known only from an agricultural landscape, but it is unknown whether it is at risk from agricultural development.

Conservation Actions [top]

Conservation Actions: Conservation Actions
This frog may occur in Cutervo National Park (Aguilar et al. 2010), however more surveys are needed to confirm this. No species-specific conservation measures are known to be in place. 

Research Needed
More information is needed on this species' distribution, population status, natural history and threats.
