Pristimantis acerus is a species of frog in the family Craugastoridae. It is endemic to Ecuador and only known from the Napo Province, in the area of its type locality between Papallacta and Cuyujúa.[3][4] This species is rated as Endangered by the IUCN.[1] Common name Papallacta robber frog has been coined for it.[3]
Etymology
The specific name acerus is Greek and refers to the absence of tubercles on the eyelid, heel, and tarsus.[2]
Description
Three males in the typw series measure 25–34 mm (0.98–1.34 in) and the only female 45 mm (1.8 in) in snout–vent length.[2][4] The snout is subacuminate in dorsal view and pointed or protruding in lateral profile. The canthus rostralis is relatively sharp. The tympanum is distinct. Both fingers and toes bear broad discs; the fingers have ill-defined lateral fringes and the toes indistinct lateral keels. The dorsum is black or dark grey; dorsal skin is smooth. The venter is dark grey to dark greyish brown. Males have creamy brown throats.[2]
Habitat
Pristimantis acerus is known from the cloud forests of the Andes at elevations between 2,660–2,750 m (8,730–9,020 ft) asl.[1][4] A specimen was found under a log at daytime, while the others were found at night on bushes 0–2 m (0.0–6.6 ft) above the ground.[2] Likely threat to this species, not known from any protected area, is deforestation caused by agriculture, logging, and human settlements.[1]
