Nymphargus bejaranoi is a species of frog in the family Centrolenidae. It is endemic to the eastern slopes of the Bolivian Andes in the Cochabamba, Chuquisaca, La Paz, and Santa Cruz departments.^[3] The specific name bejaranoi honors Gastón Bejarano,^[2] a Bolivian zoologist and Director of Forestry and National Parks, Ministry of Agriculture.^[4] Common name Bolivian Cochran frog has been coined for this species.^[1]^[3]

Description

[edit]

Adult males measure 23.6–24.4 mm (0.9–1.0 in)^[2]^[5] and adult females about 26.5 mm (1.04 in) in snout–vent length, the latter being based on the holotype of Centrolenella flavidigitata,^[6] later identified as the first female of Nymphargus bejaranoi.^[7] The snout is short^[2] and truncate or rounded in dorsal view and truncate or sloping in lateral profile.^[7] The eyes are moderately large. The tympanum is distinct but its upper part is concealed by the supra-tympanic fold. The fingers have broad discs and some webbing between the last two fingers. The toes are about one-half webbed and have discs that are slightly smaller than those on the fingers.^[2] Males in reproductive state^[5]^[7]^[8] have the dorsum covered by spicules.^[2] The dorsum is dark green;^[2] the spicules appear off-white in living specimens.^[8]

Habitat and conservation

[edit]

Nymphargus bejaranoi live in wet montane forest, including cloud forest and Yungas forest, at elevations of 1,600–2,400 m (5,200–7,900 ft) above sea level. It is an arboreal species found in vegetation close to streams and small waterfalls. It was formerly a common species, has massively decline as its habitat has become threatened by agricultural development and pollution as well as the development of roads. Its range includes several national parks.^[1]

Being ranked as "endangered" on the IUCN Red List, it is now incredibly rare. After a sighting in 2002, it was not seen for over 18 years. It was rediscovered in 2020 in Carrasco National Park during a mission to rescue reptiles and amphibians whose habitat would be threatened by a planned hydroelectric project. Three frogs were taken to an amphibian conservation center for the purpose of captive breeding.^[9]
