Cryptobatrachus ruthveni is a species of frogs in the family Hemiphractidae. It is endemic to the western flank of the Sierra Nevada de Santa Marta in northern Colombia. [1] [3] [4] The specific name ruthveni honors Alexander Grant Ruthven, an American herpetologist who was the first one to study . [2] [5]

Description

Adult males measure 33–45 mm (1.3–1.8 in) and adult females, based on a single specimen, 64 mm (2.5 in) in snout–vent length. The head is wider than it is long and wider than the body in females but not in males or juveniles. The snout is subacuminate in dorsal view but rounded in profile. The tympanum is larger in males than in females; the supratympanic fold is prominent. The dorsolateral folds are thin. Skin on the dorsum is finely granular with scattered larger warts. The fingers have no webbing. The finger and toe tips bear expanded disks. Subarticular adhesive pads are present. Alcohol-preserved specimens are dorsally brown with pale brown blotches on the back and cream spots on the flanks. The limbs are pale brown with darker brown bands. [2]

Cryptobatrachus ruthveni is externally nearly indistinguishable from Cryptobatrachus boulengeri , but has more enlarged tubercles on its dorsum. An osteological difference is that C. ruthveni lacks the lateral expansion of the anterior part of the braincase seen in C. boulengeri. [2]

Female frogs carry the eggs on their back. [2] The eggs have direct development [1] (i.e., there is no free-living larval stage [6] ).

Habitat and conservation

Cryptobatrachus ruthveni occurs in riparian habitats in creeks at elevations of 1,000–1,600 m (3,300–5,200 ft) above sea level. It is abundant within its small known range. It is threatened by habitat loss and agrochemical pollution mainly caused by coffee plantations. It is not known to occur in protected areas. [1]

<i>Cryptobatrachus</i> Genus of amphibians

Cryptobatrachus is a genus of frogs in the family Hemiphractidae. They are found in Colombia and Venezuela. They are also known as backpack frogs, 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.

"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. The generic placement of this species within the subfamily Centroleninae is uncertain. The specific name medemi honors Fred Medem, collector of the holotype. Common name Medem giant glass frog has been coined for it.

Osteocephalus cabrerai is a species of frog in the family Hylidae. It is found in the Amazon Basin in Brazil (Manaus), northeastern Peru, Ecuador, Colombia, Guyana, and French Guiana, possibly wider. Some earlier records refer to Osteocephalus buckleyi.

Atopophrynus is a genus of frogs. It is monotypic, being represented by a single species, Atopophrynus syntomopus, also known as the Sonson frog. Its taxonomic placement within the superfamily Brachycephaloidea is uncertain, although many sources place it in the family Craugastoridae. It is endemic to Colombia and only known from its type series from Sonsón, in the Cordillera Central, Antioquia Department.
