Pristimantis waoranii is only known from the type locality: ca 2.5 km west-northwest of Tiputini Biodiversity Station (0 38' 18.49" S, 76 08' 56.69" W, 217 masl), near the border of Yasuni National Park, along the Tiputini River, Province of Orellana, Ecuador (McCracken et al., 2007).
Habitat and Ecology
The species inhabits the sub- to upper canopy strata of lowland evergreen broadleaf rain forest of the upper Amazon Basin. Individuals of this species have been found in the water-filled outer bracts of tank bromeliads at heights ranging between 23.5 and 38.0 m, on branches or trunks of trees in terra firme forest. Another syntopic anuran species is Pristimantus aureolineatus (McCracken et al., 2007).
This is considered to be a common species (S. McCracken, pers. comm. 2008).
Deforestation and forest fragmentation caused by petroleum operations and subsequent colonization were observed in the region where this species occurs (S. McCracken, pers. comm. 2008).
The species occurs at Tiputini Biodiversity Station and Yasuni National Park.
In the Eleutherodactylus lacrimosus assemblage of the greater unistrigatus group according to the original publication. It is also suggested that the species is likely placed within the genus Pristimantis (McCracken et al., 2007). Pristimantis waoranii can be distinguished from other similar species by a combination of morphological features and different colour patterns (see McCracken et al., 2007).
