Listed as Least Concern since, although its extent of occurrence (EOO) is 18,344 km2, it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, and has a presumed large and stable population.
|Previously published Red List assessments:|
|Range Description:||This species' geographic range is the northeastern slope of the Andes of Peru, within the Cordillera Central (Departments of Amazonas and San Martin). Its known localities lie within the Río Cainarachi drainage (two sites) and the Río Marañón valley (two sites) (Duellman 2004), and it has an estimated altitudinal range of 400–1,700 m asl (Aguilar et al. 2010). It might occur more widely. Its EOO is 18,344 km2.|

|Population:||In the Cainrachi area, this species is abundant in both primary and secondary forested areas in both mid and low elevations (J. Brown pers. comm. April 2017). It is considered to be the most abundant Dendrobatid (J. Brown pers. comm. April 2017) and the population is thought to be stable.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It is a diurnal, terrestrial species known from both humid and dry pre-montane and lowland forest (Duellman 2004), which is associated with streams. It has been recorded from disturbed (partially cutover) rainforest (Duellman 2004), implying tolerance of some degree of habitat modification. Larvae are carried to streams by the female.|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records 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).|
|Major Threat(s):||Because of the large areas of suitable habitat available in protected areas to this species there are no major threats. Outside protected areas, there is some localized habitat loss through different human activities, principally agriculture.|
This species occurs within the Santiago Comaina Reserved Zone and the Alto Mayo protected area. No species-specific conservation measures are known.
More information is needed on EOO, area of occupancy (AOO), population status, natural history and threats.
