Cryptobatrachus ruthveni | |
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]
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] ).
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]
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.
Cryptobatrachus boulengeri, also known as Boulenger's backpack frog, is a species of frogs in the family Hemiphractidae. It is endemic to Sierra Nevada de Santa Marta in northern Colombia. The specific name honours George Albert Boulenger, an eminent herpetologist.
Cryptobatrachus fuhrmanni commonly known as Fuhrmann's backpack frog is a species of frog belonging to the family Hemiphractidae. It is endemic to Colombia and occurs on all three Andean cordilleras: the eastern slope of the Cordillera Occidental, the northern and eastern flanks of the Cordillera Central, and the western slope of the Cordillera Oriental. The specific name fuhrmanni is in honor of Otto Fuhrmann, a Swiss zoologist and helminthologist.
Pristimantis factiosus is a species of frog in the family Strabomantidae. It is endemic to the eastern slopes of the Cordillera Central in Colombia and only known from near its type locality, El Estadero in Samaná, Caldas Department, and from Anorí, Antioquia Department. The IUCN SSC Amphibian Specialist Group, however, has mapped its distribution as continuous between these locations. The specific name factiosus refers to sexual dimorphism in coloration of the flanks.
Pristimantis leptolophus is a species of frog in the family Strabomantidae. It is endemic to Colombia and known from the páramos of the Colombian Massif and Cordillera Central in the departments of Cauca and Huila. The specific name leptolophus is derived from Greek leptos ("thin") and lophos ("crest") and refers to the low dorsolateral folds of this frog. Common name volcano robber frog has been coined for it.
Pristimantis myops is a species of frog in the family Strabomantidae. It is endemic to Colombia and known from the Cordillera Occidental in Antioquia, Chocó, and Valle del Cauca Departments. The specific name myops is Greek meaning "near-sighted", in allusion to the interocular fold that resembles the bridge of a pair of glasses, as well as to the small size of these frogs, which forced the species describer to wear reading glass while collecting them.
Pristimantis ocreatus is a species of frog in the family Craugastoridae. Although often reported as being endemic to the Andes of northern Ecuador, it has also been reported from extreme southern Colombia ; the possibility of range extension to Colombia has been acknowledged. Its type locality is the west slope of volcano Chiles in the Carchi Province, and common name Carchi robber frog has been coined for it. These frogs have pale hands and feet, as if wearing gloves and socks—hence the specific name ocreatus, which is Latin and means "wearing leggings" or "booted".
Pristimantis piceus is a species of frog in the family Strabomantidae. It is endemic to Colombia and occurs in the Cordillera Central between the Antioquia Department in the north and the Cauca Department in the south. Many specimens are black in color, and the specific name piceus is Latin meaning "pitch-black".
Pristimantis polemistes is a species of frogs in the family Strabomantidae. It is endemic to Colombia and only known from the vicinity of its type locality in Urrao, Antioquia Department, on the western flank of the Cordillera Occidental. The specific name polemistes is Greek for "warrior" and refers to the insurgents that operated in the area of the type locality.
Serranobatrachus ruthveni is a species of frog in the family Craugastoridae. It is endemic to the north-western slope of the Sierra Nevada de Santa Marta in the Magdalena Department, northern Colombia. The specific name ruthveni honors Alexander Grant Ruthven, an American herpetologist. Common name Ruthven's robber frog has been coined for this species.
Pristimantis scoloblepharus is a species of frog in the family Strabomantidae. It is endemic to Colombia and is only known from three localities in the Cordillera Central in the Antioquia Department. The specific name scoloblepharus is derived from Greek skolos (=pointed) and blepharis (=eyelash) and refers to the large tubercle in its eyelid. Common name Los Patos robber frog has been coined for it.
Pristimantis scopaeus is a species of frog in the family Strabomantidae. It is endemic to Colombia and occurs in the Cordillera Central in the Tolima and Quindío Departments. Pristimantis scopaeus is a dwarf species: adult males in the type series were first mistaken for juveniles of Pristimantis simoteriscus, which itself already is a small species. The specific name scopaeus is Latinization of the Greek skopaios, meaning "dwarf".
Pristimantis tribulosus is a species of frog in the family Strabomantidae. It is endemic to Colombia and is only known from the vicinity of its type locality near Samaná in the Caldas Department, on the eastern slope of the Cordillera Central. The specific name tribulosus, meaning "thorny", refers to the numerous tubercles that cover the upper surfaces of this species.
Pristimantis veletis is a species of frog in the family Strabomantidae. It is endemic to Colombia and is only known from the vicinity of its type locality in Samaná and Pensilvania municipalities in the Caldas Department, on the eastern slope of the Cordillera Central. The specific name veletis is Latin from "skirmisher". It alludes to the resemblance of the color pattern of this frog to the camouflage clothing of the guerillas that were present in the area of the type locality, as well as to the chin pattern that loosely resembles the chevrons in some military uniforms.
Gastrotheca abdita is a species of frog in the family Hemiphractidae. It is endemic to Peru and only known from the Cordillera Colán in the Amazonas Region. The specific name abdita is Latin for "exiled" or "removed" and refers to the geographic isolation of the Cordillera Colán. Common name Cordillera Colan marsupial frog has been coined for it.
Gastrotheca dunni is a species of frog in the family Hemiphractidae. It is endemic to the northern part of the Cordillera Occidental in northern Antioquia, Colombia. The specific name dunni honors Emmett Reid Dunn, an American herpetologist. Common name Dunn's marsupial frog has been coined for it.
Gastrotheca excubitor is a species of frog in the family Hemiphractidae. It is endemic to southern Peru and occurs in the Amazonian slopes and crests of the Cordillera Oriental in the Cusco Region; records from the Cajamarca Region are likely erroneous. It is likely to include cryptic species. Common name Abra Acanacu marsupial frog has been coined for it.
Pseudophilautus singu is a species of frog in the family Rhacophoridae, endemic to southwestern Sri Lanka. It is known from the Kanneliya-Dediyagala-Nakiyadeniya, Kitulgala, and Kottawa Forest Reserves and from the Sinharaja World Heritage Site.
