Pristimantis w-nigrum, also known as the Zurucuchu robber frog or w rainfrog, is a species of frog in the family Strabomantidae. It is found on both Pacific and Amazonian slopes of the Andes in Colombia, Ecuador, and northern Peru. [2] The species is divided to at least eight clades that are genetically highly divergent but morphologically similar; it may be a species complex. [3]

Description

Pristimantis w-nigrum males measure 29–47 mm (1.1–1.9 in) in snout–vent length and females measure 44–57 mm (1.7–2.2 in). Live specimens are easily recognized by a colour pattern of yellow with black markings on the groin, anterior and posterior surfaces of thighs, and concealed shank. Tympanum is distinct. [4]

Habitat

The natural habitats of Pristimantis w-nigrum are cloud forest and sub-páramo, but it occurs also in deforested and disturbed areas. [1] It is a nocturnal species [4] that can be found perched on vegetation up to 3 metres above ground; during the day it can be found on fallen leaves. It is a common species although it has declined in many areas. [1]
