This species is known from six geographical localities in eastern San Martín region and one locality in southwestern Loreto region, Peru. Each geographical locality is herein considered as one threat-defined location, so a total of seven threat-defined locations. This frog is found between 200-800 m asl. Its range, taken as a proxy for extent of occurrence (EOO), is approximately 10,059 km2, although it is possible that this species may be more widespread than currently understood as there are still areas of these two regions that have not yet been surveyed. However, this frog does appear to be restricted to areas adjacent to small and slow streams (Twomey and Brown 2009), which are unevenly distributed in the regions.
Habitat and Ecology
It inhabits old growth, secondary and riparian lowland tropical forest. It is active near small streams, and tadpoles appear to be deposited in slow-moving streams (Twomey and Brown 2009). It appears to be restricted to the vicinity of small and slow-moving streams (Twomey and Brown 2009).
Approximately 30 individuals were found over 20 person/day surveys between July 2005 and June 2007 (von May et al. 2008). An additional single individual was recorded in 2005 (D. Edmond pers. comm. in Amphibian Red List Assessment Forum April 2013). No further population information is available for this species, although a decline in the number of mature individuals is suspected in view of illegal export - and therefore harvesting - activities.
Its lowland rainforest habitat is being affected by encroaching agriculture due to farmers clearing new farms (Twomey and Brown 2009). It is also being illegally harvested and exported.
It is not known to occur in any protected areas, although it may possibly occur within Cordillera Azul National Park. Land protection in the areas where this species occurs is needed as is improved enforcement for preventing its illegal collection and export. Further research is needed into its distribution, population status and ecology, and targeted surveys are required to determine if it occurs within Cordillera Azul National Park.
Red List Status
Listed as Vulnerable given that its extent of occurrence (EOO) is estimated to be 10,059 km2, it is considered to occur in seven threat-defined locations, and there is a continuing decline in the extent and quality of its available habitat in northern Peru as well as a suspected decline in the number of mature individuals due to illegal collection and export for the pet trade.
This species is very similar to Ameerega petersi. There might be a need to re-examine the relationship between these two taxa.
