Nymphargus bejaranoi

Adult males measure 23.6–24.4 mm (0.9–1.0 in)[3][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[3] 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.[3] Males in reproductive state[5][7][8] have the dorsum covered by spicules.[3] The dorsum is dark green;[3] the spicules appear off-white in living specimens.[8]

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]

Despite being ranked as Least Concern on the IUCN Red List, this status may be outdated, as it is now incredibly rare.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]
