Plectrohyla sabrina, also known as the Sierra Juarez treefrog, is a species of frog in the family Hylidae. It is endemic to the northern slopes of Sierra de Juárez in northern Oaxaca, Mexico.[1][3] The specific name sabrina is Latin for river nymph and refers to the close association of this species with streams.[2]

Taxonomy

A revision of the family Hylidae from 2016 places this species in the genus Sarcohyla,[4] but this classification is not yet widely adopted[1][5] and as of late 2016, the Amphibian Species of the World labels it as "provisional".[3] It belongs to the "Plectrohyla bistincta group" with the genus Plectrohyla,[2][3] all of them moved to Sarcohyla in the 2016 revision.[4]

Description

Plectrohyla sabrina is a small, slender-limbed frog. Males measure 27–30 mm (1.1–1.2 in) and females 34–41 mm (1.3–1.6 in) in snout–vent length. The tympanum is absent. The fingers lack webbing whereas the toes are about three-fourths webbed. The dorsum is light chocolate brown with mostly green and some dark brown mottling. There is a dark brown stripe running from nostril along the canthus to back of arm. At night, they might be a bright leaf green. Breeding males do not have nuptial spines.[2]

Habitat and conservation

The natural habitats of this species are cloud forest in the highlands of the Sierra de Juárez at elevations of 1,580–2,020 m (5,180–6,630 ft) above sea level. It occurs along streams in moist and rocky habitats with abundant aquatic vegetation.[1]

Population of Plectrohyla sabrina is declining. It is threatened by habitat loss and chytridiomycosis.[1]
