Pristimantis orcesi is a species of frog in the family Strabomantidae. It is endemic to the Andes of central and northern Ecuador.[1][3][4] The specific name orcesi honors Gustavo Orcés [es], an Ecuadorian naturalist.[2][4][5] Common names Orces robber frog[4] and Bolivar robber frog have been proposed for this species.[3]

Description

Adult males measure 24–30 mm (0.9–1.2 in) and adult females 35–36 mm (1.4–1.4 in) in snout–vent length.[6] The snout is short and rounded. The tympanum is visible. The fingers and toes bear lateral fringes as well as discs at their tips. The dorsum is dark chocolate-brown or black with white warts. The venter is paler than the dorsum. The iris is deep chocolate-brown. Males have a vocal sac.[2][6]

Habitat and conservation

Pristimantis orcesi is associated with terrestrial bromeliads and rocks in dry páramo grassland at elevations of 3,160–3,800 m (10,370–12,470 ft) above sea level near small steams that retain some moisture.[6][4] Development is direct[1] (i.e., there is no free-living larval stage[7]). It is potentially threatened by feral cows and fire. It is known from the Llanganates and Sangay National Parks and its range overlaps with some other protected areas.[1]
