This species is endemic to Peru and known from the type locality of Myaria, District of Echarate, Province of La Convención (Cusco Region; Lehr et al. 2007), Cocha Cashu Field Station (Madre de Dios Region), and two localities in the Río Abujao watershed (Ucayali Region). It occurs at elevations from 320–400 m asl.
Habitat and Ecology
This species inhabits primary lowland rainforest. Individuals have been found on leaves ca 150–800 cm above ground. It is suspected that the species could be a canopy dweller. It is expected to reproduce by direct development, as with other congeners. Other species of Pristimantis found at Myaria are P. diadematus, P. fenestratus, P. ockendeni and P. peruvianus (Lehr et al. 2007).
The species is known only from the type series. However, this is a canopy dweller and the forest canopy in this area has not been studied thoroughly, therefore it is likely more common than surveys have revealed (E. Lehr pers. comm. 2008, December 2017).
Deforestation for small-holder agriculture has been observed in the region where the species occurs (E. Lehr pers. comm. 2008), however it is a widespread species with suitable lowland habitat remaining throughout its range.
It has been recorded from within Manu National Park.
More information is needed on this species' distribution, population status, and trends.
Red List Status
Data Deficient (DD)
Listed as Least Concern in view of its wide distribution, presumed large population, and remaining suitable habitat across its range.
Included in the genus Pristimantis sensu Heinicke et al. (2007) (Frost 2007). In the Eleutherodactylus unistrigatus group according to the original description (Lehr et al. 2007). The species is distinguished from other similar species by a combination of morphological features and colour patterns (Lehr et al. 2007).
