Cryptobatrachus is a genus of frogs in the family Hemiphractidae. They are found in Colombia and Venezuela.[1][2] They are also known as backpack frogs,[1] as the females have the habit of carrying their egg clutch on their backs until the young hatch; this behavior also occurs in the related hemiphractid genera Hemiphractus and Stefania.[3][4]
Description
Cryptobatrachus have a treefrog-like habitus.[3] Males measure 27–52 mm (1.1–2.0 in) and females 48–75 mm (1.9–3.0 in) in snout–vent length.[2] Fingers have no webbing whereas the toes are webbed. The finger and toe tips bear disks that are larger on the former.[5] Also adhesive pads are present on the penultimate subarticular tubercles on the fingers.[2][5] Males lack vocal sac[2] and these frogs appear not to vocalize.[5]
Species
There are six species in the genus Cryptobatrachus:[1][2]
- Cryptobatrachus boulengeri Ruthven, 1916
- Cryptobatrachus conditus Lynch, 2008[5]
- Cryptobatrachus fuhrmanni (Peracca, 1914)
- Cryptobatrachus pedroruizi Lynch, 2008[5]
- Cryptobatrachus remotus Infante-Rivero, Rojas-Runjaic, and Barrio-Amorós, 2009
- Cryptobatrachus ruthveni Lynch, 2008[5]
The AmphibiaWeb lists the six species above, but also Cryptobatrachus nicefori,[6] which the Amphibian Species of the World places in the hylid subfamily Cophomantinae as "Hyla" nicefori, indicating uncertain generic affiliation.[7]
Habitat and ecology
Cryptobatrachus occur on humid forested slopes in the mountain ranges of northern Colombia and northeast Venezuela at elevations of 360–2,400 m (1,180–7,870 ft) above sea level. They are nocturnal and perch on low bushes or cling to rocks and cliffs in spray zones of waterfalls.
