Ctenophryne barbatula

Ctenophryne barbatula is a species of frog in the family Microhylidae. It is endemic to Peru and only known from the Yanachaga–Chemillén National Park, its type locality in the Pasco Region.[1][2] The specific name barbatula is the diminutive of the Latin barbatus, meaning "bearded". It refers to the beard-like spines under the lower jaw of males.[3]

Description

Adult males measure 22–25 mm (0.87–0.98 in) and adult females 26–27 mm (1.0–1.1 in) in snout–vent length. The head is nearly as broad as the body. The snout is truncate. The eyes are relatively large. The supra-tympanic fold is moderate. Males have white spines in most parts of the body while females have spines only in the region of tympanum (tympanic annulus and tympanic membrane are absent). The dorsum and venter of preserved specimens are uniform brown and lack pattern; the color of live individuals is not known. The fingers and toes have rounded tips; the toes have basal webbing.[3]

Habitat and conservation

Ctenophryne barbatula inhabits forested areas at around 2,500 m (8,200 ft) above sea level. Its diet consists of various arthropods; the composition suggests that it is a leaf litter frog.[1][3]

Despite occurring within a protected area, Ctenophryne barbatula is considered Endangered because of its small known range and habitat loss in the area.[1]

gollark: Did you know? Our bees are representing you as a product of prime numbers as we speak.
gollark: Fascinating. Maybe it treats me not defining a cloak mask thing as denying it. How strange.
gollark: As far as I can tell it was *always* available.
gollark: Define the type and have it automatically write it out.
gollark: Those are only 10% of demand.
