Dendropsophus arndti | |
Dendropsophus arndti is a species of "clown tree frogs" [3] described in 2017 [2] that lives in the Amazon basin of Bolivia, Peru, and Brazil. [1] [4] The specific name arndti honors professor Rudolf G. Arndt, in recognition of his financial support for research and nature conservation. Accordingly, common name Arndts' treefrog has been coined for it. [2]
This species is found in the Amazon basin of southeastern Peru, Bolivia (Beni and Santa Cruz Departments) [1] [4] and western Brazil (Rondônia, possibly east to Mato Grosso). [1]
Adult males measure 28–32 mm (1.1–1.3 in) and adult females, based on a single specimen, 33 mm (1.3 in) in snout–vent length. The head is broader than it is long. The snout is short and rounded in dorsal view, truncate in profile. The eyes are large and protuberant. The tympanum is concealed beneath skin, but the tympanic annulus is visible below skin. The supratympanic fold is faint but conceals the tympanic annulus dorsally. The fingers and toes are partially webbed and bear large discs (smaller on the toes than on the fingers). The skin is smooth with varying coloration. Most specimens have clear dorsolateral bands, but some have a reticulated dorsal pattern. The background color is dark brown to brown, and the bands, spots, and reticulations are white to bright yellow. [2]
Dendropsophus arndti has been recorded in Beni savanna, Chiquitano dry forests, and Bolivian Yungas at elevations of 148–529 m (486–1,736 ft) above sea level. Specimens have found perched in vegetation up to 1.4 m (4 ft 7 in) above the ground or water in range of habitat types, often near water (river shores, temporary swamplands, and artificial ponds) but also along forest edges. [2]
The IUCN Red List of Threatened Species classifies Dendropsophus arndti as of "least concern" because of its relatively wide distribution in mosty intact habitat. Human-induced fire is a localized threat that is getting more frequent. [1]
Rhinella lindae is a species of toad in the family Bufonidae. It is endemic to Colombia and known from its type locality, Murri in the municipality of Frontino, and from Las Orquídeas National Natural Park, both on the western slope of the Cordillera Occidental, Antioquia Department. The specific name lindae honors Linda Trueb, an American herpetologist. However, common name Murri beaked toad has been coined for this species.
Cochranella resplendens is a species of frog in the family Centrolenidae. It is found in the upper Amazon Basin in southwestern Colombia, eastern Ecuador, northern Peru, and Bolivia. There are also isolated records from the Cordillera Central in Antioquia, Colombia, and Amapá in northern Brazil. The specific name resplendens is derived from the Latin verb resplendo and hints to the jewel-like appearance of this frog. It is sometimes known as the resplendent Cochran frog or resplendent glassfrog.
Vitreorana ritae is a species of frog in the glass frog family (Centrolenidae). It is found in Amazonian Brazil, Colombia, Ecuador, and Peru, and in southern Guyana, eastern Suriname, and French Guiana. Its natural habitats are tropical moist lowland forests and rivers. It is threatened by habitat loss.
Dendropsophus garagoensis is a species of frog in the family Hylidae. It is endemic to the eastern slope of the Cordillera Oriental in Boyacá Department, Colombia. Common name Garagoa treefrog has been proposed for it.
Dendropsophus joannae is a species of frogs in the family Hylidae. It is known from the Pando Department, northern Bolivia, western Brazil, and Madre de Dios Region of southeastern Peru. It is similar to Dendropsophus leali but is smaller, has a shorter snout, more protuberant eyes, and more tuberculate dorsal skin. The specific name joannae honors Mrs. Jo Ann Oxley Foster, a BIOPAT patron supporting taxonomic research and nature conservation.
Dendropsophus marmoratus is a species of frog in the family Hylidae. It is found in the Amazon rainforest and montane forests in the eastern piedmont, in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, intermittent freshwater marshes, and heavily degraded former forest. "Marmoratus" in Latin means "marble," perhaps referring to the dorsal coloring pattern. It is threatened by habitat loss.
Dendropsophus riveroi is a species of frog in the family Hylidae. It is found in the upper Amazon Basin in western Brazil, Bolivia, Peru, Ecuador, and southern Colombia. In Ecuador it has been mixed with the newly described Dendropsophus shiwiarum. The specific name honours Juan A. Rivero.
Dendropsophus stingi is a species of frogs in the family Hylidae. It is endemic to Colombia and occurs on the eastern slope of the Cordillera Oriental in the Boyacá Department. The species was named after celebrity musician Sting in recognition of his "commitment and efforts to save the rain forest". Despite this, common name Kaplan's Garagoa treefrog has been coined for it.
Osteocephalus helenae is a species of frog in the family Hylidae. It is widely distributed in the Amazon Basin and is known from the lowlands of Bolivia, Peru, Brazil, Colombia, Venezuela, Guyana, and French Guiana. The specific name helenae honors Helen Beulah Thompson Gaige, an American herpetologist. Common name Helena's [sic] treefrog has been proposed for it.
Scinax fuscomarginatus is a species of frog in the family Hylidae. It is found in northwestern Argentina, Paraguay, eastern Bolivia, southern, central, and eastern Brazil, and in scattered localities in the lowlands of eastern Venezuela and savannas of Guyana and southern Suriname as well as adjacent Brazil. As currently defined, it is one of the most widespread Neotropical frogs; the northernmost records refer to what was formerly recognized as Scinax trilineatus. Common name brown-bordered snouted treefrog has been coined for this species.
Adelophryne pachydactyla is a species of frog in the family Eleutherodactylidae. It is endemic to the coastal area of south-central Bahia state, Brazil. Some specimens first identified as A. pachydactyla have later been found to represent a new species, Adelophryne mucronatus; the two species can occur in sympatry. The specific name pachydactyla is derived from Greek pachys (=thick) and daktylos (=finger), referring to the thick, short, swollen fingers of this frog.
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.

It is endemic to Peru and known from its type locality, the Río Cosñipata Valley, on the northeastern slopes of the Cadena de Paucartambo, a frontal range of the Cordillera Oriental in Cusco Region, and from the Apurímac River valley. Its range might extend into Bolivia. The specific name salaputium is Latin meaning "dwarf" and refers to the small size of this species. Common name river robber frog has been coined for it.

It is known from its type locality on the Cordillera de Carpish, Huánuco, and from near Juanjuí in the San Martín Region.

It is endemic to Bolivia and only known from the region of Unduavi in the Unduavi Valley, Sud Yungas Province, La Paz Department.
