Pristimantis acerus
Pristimantis acerus is a rain frog in the family Craugastoridae (order Anura), recorded as Endangered and tied to Ecuador.
Appearance
Three males in the type series measure 25–34 mm (0.98–1.34 in), and the only female measures 45 mm (1.8 in) in snout–vent length. The snout is subacuminate in dorsal view and pointed or protruding in lateral profile. The dorsum is black or dark grey. Dorsal skin is smooth.
Range and 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. 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. A likely threat to this species is deforestation caused by agriculture, logging, and human settlements.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Direct-developing rainfrogs live in wet forest. They do not need a pond, which is why a logged hillside can erase a species.
Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.
In crisis
This species is rated as Endangered by the IUCN.
Direct-developing frogs vanish with the forest floor. There is no pond population waiting off-site.
