It is endemic to the northern slopes of Sierra de Juárez in northern Oaxaca, Mexico.[1][4] The specific name sabrina is Latin for river nymph and refers to the close association of this species with streams.[2] TaxonomyA revision of the family Hylidae from 2016 places this species in the genus Sarcohyla,[6] but this classification is not yet widely adopted[1] and as of late 2016, the Amphibian Species of the World labels it as "provisional".[4] It belongs to the "Plectrohyla bistincta group" with the genus Plectrohyla,[2][4] all of them moved to Sarcohyla in the 2016 revision.[6] DescriptionPlectrohyla sabrina is a small, slender-limbed frog. Males measure {{convert|27|-|30|mm|abbr=on}} and females {{convert|34|-|41|mm|abbr=on}} 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 conservationThe natural habitats of this species are cloud forest in the highlands of the Sierra de Juárez at elevations of {{convert|1580|-|2020|m|abbr=on}} 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] References1. ^1 2 3 4 {{cite journal | author1 = Santos-Barrera, G. | author2 = Canseco-Márquez, L. | author3 = Mendelson III, J. | title = Plectrohyla sabrina | journal = IUCN Red List of Threatened Species | volume= 2006 | page = e.T55639A11345830 | publisher = IUCN | year = 2006 | doi = 10.2305/IUCN.UK.2006.RLTS.T55639A11345830.en }} [2][3][4]>2. ^1 2 3 4 {{cite journal|last1=Caldwell|first1=J.|title=A re-evaluation of the Hyla bistincta species group, with descriptions of three new species (Anura: Hylidae) |journal=Occasional Papers of the Museum of Natural History, the University of Kansas |date=1974 |volume=28 |pages=1–37 |doi=10.5962/bhl.part.14776}} 3. ^1 2 {{cite journal|last1=Duellman |first1=William E. |last2=Marion |first2=Angela B. |last3=Hedges |first3=S.
