Pristimantis piceus

Pristimantis piceus is a species of frog in the family Craugastoridae. It is endemic to Colombia and occurs in the Cordillera Central between the Antioquia Department in the north and the Cauca Department in the south.[1][2][4] Many specimens are black in color, and the specific name piceus[3] is Latin meaning "pitch-black".[5]

Description

Adult males measure 29–41 mm (1.1–1.6 in) and adult females 40–50 mm (1.6–2.0 in) in snout–vent length. The snout is long, subacuminate in dorsal view, and rounded in lateral profile. The tympanum is distinct, but the supra-tympanic fold obscures its upper edge. Skin of the dorsum has numerous minute, low warts. The dorso-lateral fold is not present. The venter is areolate. The fingers have lateral keels and discs. The toes have fleshy keels and discs that are smaller than the finger discs. Coloration is variable, usually uniformly black, reddish-brown, or dark brown with a pale blue peri-ocular ring. Many specimens have orange spots on the flanks. The margin of the mandible shows usually some White flecks. The iris is black, chocolate, or dull bronze, with yellowish flecks. Males have large, sub-gular vocal sac.[3]

When disturbed, these frogs may secrete a white or blue-white mucus. Presumably, this sticky secretion serves defensive purposes.[3]

Habitat and conservation

Pristimantis piceus occur in cloud forest, sub-páramo, and páramo habitats[1][4] at elevations of 2,400–3,400 m (7,900–11,200 ft) above sea level.[4] They are at active night when they can be found on vegetation, especially in open areas on top of weeds. During the day, they occur on the ground, among low grass, or under logs and rocks.[1]

It is a relatively widespread and common species that can locally suffer from habitat loss caused by deforestation, agriculture development, and illegal crops. It occurs in several protected areas.[1]

gollark: Yes.
gollark: Like mine. Want a link?
gollark: Besides, it would be about the same between everyone, presumably.
gollark: What? No. You can't measure that.
gollark: Someone truncated it because it was long.
