"Centrolene" medemi is a species of frog in the family Centrolenidae. The species occurs in the Cordillera Oriental in the Tolima, Caquetá, and Putumayo Departments in Colombia and adjacent Napo in Ecuador.[3][4][5] The generic placement of this species within the subfamily Centroleninae is uncertain (incertae sedis).[3][6] The specific name medemi honors Fred Medem, collector of the holotype.[2] Common name Medem giant glass frog has been coined for it.[3]
Description[]
Adult males measure 26–31 mm (1.0–1.2 in) and adult females 35–44 mm (1.4–1.7 in) in snout–vent length.[5][7] The snout is rounded in dorsal profile and truncated to slightly protruding when viewed laterally. The tympanum is indistinct and partly covered by the supra-tympanic fold. The fingers have absent to extensive webbing (from inner to outer fingers). The toes are extensively webbed.[5] The dorsal surfaces of head, body, and limbs are olive green to grayish brown and bear large cream spots. The ventral parietal peritoneum is white. Adult males have a large humeral spine. The pre-pollical spine is not separated from the first finger. The iris is grayish brown and has dark reticulation.[7]
Habitat and conservation[]
This species lives on streamsides in montane cloud forests[1][5] at elevations of 790–1,800 m (2,590–5,910 ft) above sea level.[5] It also occurs in secondary forest, as long as there is good vegetation cover close to streams. The eggs are laid on leaves overhanging the water.[1]
It is locally common in Colombia, but only one specimen, collected in 1975, is known from Ecuador.[1][5] The specific threats are poorly known but probably include habitat loss, introduction alien predatory fishes, and pollution from the spraying of illegal crops. Chytridiomycosis might also be a threat.[1]
