Sarcohyla cembra

The specific name cembra is Latin for "timber" and refers to the pine-oak forest this species inhabits.[2]

It was initially thought that the female specimen that became the holotype of Sarcohyla miahuatlanensis could be a female Sarcohyla cembra, but it was eventually identified as a new, distinct species. Nevertheless, the two species are morphologically similar.[6]

The holotype is a male that measures 37 or 36.1 mm (1.46 or 1.42 in) in snout–vent length, depending on the source.[2][4] The second specimen, also a male, measures 40.4 mm (1.59 in) SVL.[4] The body is moderately robust. The tympanum is small and indistinct. Skin is smooth on the dorsum and limbs, weakly granular on venter, chin, and ventral surfaces of thighs. The fingers are without webbing whereas the toes are moderately webbed. The dorsum was bright greenish yellow upon capture, changing to dull green. There is brown and green reticulations along sides. The throat and chest are white. The ventral sides of limbs and belly are pinkish tan. The iris is brownish yellow.[2]

Male advertisement call is a short "wrack", often followed by a series of low "chuckles". Tadpoles found at the type locality, provisionally allocated to this species, measured up to 51 mm (2.0 in) in total length.[2]

The natural habitats of this species are pine-oak forest.[1] The holotype was found calling at night from under a piece of bark on a large log in a small stream at 2,160 m (7,090 ft) above sea level.[2] The second specimen was found inside an arboreal bromeliad on a fallen oak tree at 2,850 m (9,350 ft) asl.[4]

This species was only known from two specimens collected in 1969 and 1993,[1] until it was again found in 2011–2012.[5] Its habitat, the pine-oak forests, are under threat caused by logging and agriculture. Also chytridiomycosis might have impacted the species.[1]
