Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2011
Date Assessed: 2010-10-27
Assessor(s): IUCN SSC Amphibian Specialist Group
Reviewer(s): Lau, M. & Richards, S.
Contributor(s): Bowles, P.
Listed as Data Deficient since it has only recently been described, and there is still very little information on its extent of occurrence, status and ecological requirements. It is known from a very restricted area, but no information is available on possible or ongoing threats.

Geographic Range [top]

Range Description: The only known locality lies north of the Rio Huallaga in the upper reaches of the Amazon Basin, at an elevation of 360 m asl. This site is approximately 16 km ESE of Shapaja in San Martín Province, Region of San Martín, Peru (Duellman 2004).

Population [top]

Population: No population information is available for this species, which is known from only two specimens (Duellman 2004). There are no known recent surveys for this frog.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This diurnal species was found near a small stream in disturbed lowland rainforest, within a rocky ravine. This frog exhibits the reproductive mode typical of poison dart frogs, in which adults transport newly-hatched tadpoles to water to complete development. In the one recorded case, a male was observed carrying five larvae (Duellman 2004), but clutch size is unknown. Eggs are presumably laid in terrestrial situations, as is the case in most related species.
Systems: Terrestrial; Freshwater

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 has a very restricted range, but there is no information on major threats. Its occurrence in disturbed forest indicates a degree of resilience to habitat modification, but the extent of this tolerance is unknown.

Conservation Actions [top]

Conservation Actions: No conservation actions are currently known for this species. More information is needed on this species' distribution, population status, natural history and threats.
