Ctenophryne geayi (common name: brown egg frog, Spanish : sapito apuntado de Geay) is a species of frog in the family Microhylidae. It is widely distributed in the northern parts of South America, in the Guianas (Guyana, Suriname, French Guiana) and in the Amazon Basin in Venezuela, Colombia, Ecuador, Peru, Bolivia, and Brazil. [1] [2] [3] It might actually represent two species. [2] [4]
Adult males measure 32–43 mm (1.3–1.7 in) and adult females 42–55 mm (1.7–2.2 in) in snout–vent length. The body is rotund, and the head is narrower than the body. The snout is blunt from above and rounded, slightly projecting in profile. The tympanic ring is barely visible externally. The fingers have rounded tips. The toes have flattened tips and webbing that is more extensive in males than in females. Coloration is pale brown dorsally, with darker brown flanks and anterior and posterior surfaces of the thighs. The throat is dark grayish brown, and other ventral surfaces are dark brown with white flecks. A vertebral line might be present. There are two ventral color patterns. Specimens from the northern and western part of the range have pale flecks or very small spots, no more than 1 mm (0.04 in) in diameter but typically less. Southern specimens have larger spots, at least some of them 1.5 mm (0.06 in) or larger, up to a maximum of about 5 mm (0.2 in). [4]
Ctenophryne geayi occurs near flooded depressions and semi-permanent or seasonal ponds of old growth tropical rainforests at elevations up to 600 m (2,000 ft) above sea level. It is a secretive species that is nocturnal and fossorial, found above ground only during brief explosive periods of reproduction in pools. It can locally suffer from habitat loss but is not overall threatened; it occurs in many protected areas. [1]
Ctenophryne is a genus of microhylid frogs. They occur in southern Central America and South America. Their common names are egg frogs and Nelson frogs, the latter applying to species in the formerly recognized Nelsonophryne.
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.
Atlantihyla panchoi, also known as the Guatemala stream frog, is a species of frog in the family Hylidae. It is endemic to eastern Guatemala and is only known from three localities in the Sierra de las Minas and Montañas del Mico ranges. The specific name panchoi honors Laurence Cooper "Don Pancho" Stuart, an American herpetologist.
Sphaenorhynchus lacteus, the Orinoco lime treefrog or greater hatchet-faced treefrog, is a species of frog in the family Hylidae. It is a widely distributed species found in the Orinoco and Amazon basins in Venezuela, the Guianas, Colombia, Brazil, Ecuador, Peru, and Bolivia. It also occurs in Trinidad and Tobago.
Ctenophryne carpish is a rare and little-known species of microhylid frogs endemic to Peru. It is known from its type locality on the Cordillera de Carpish, Huánuco, and from near Juanjuí in the San Martín Region. It lacks eardrums, and at a cursory glance it resembles leptodactylid frogs of the genus Phrynopus, in which it was initially placed.
Choerophryne sanguinopicta is a species of frogs in the family Microhylidae. It is endemic to southeastern Papua New Guinea and only known from the vicinity of its type locality, the northern slope of Mt. Simpson in the Owen Stanley Range, Milne Bay Province, although it is expected to occur more widely. The specific name sanguinopictus, from Latin for sanguis ("blood") and pictus ("painted") refers to the distinctive red blotching and punctations characteristic for this species.
Austrochaperina basipalmata is a species of frog in the family Microhylidae. It is endemic to the mountain ranges of northern New Guinea and is found between Tawarin River in Papua, Western New Guinea (Indonesia) and Torricelli Mountains in Papua New Guinea.
Barygenys nana is a species of frog in the family Microhylidae. It is endemic to New Guinea and is known from the mountains of Eastern Highlands and Western Highlands Provinces, Papua New Guinea. The specific name nana refers to the small size of this species. Common name highland Papua frog has been proposed for it.
Callulops boettgeri, also known as Boettger's Callulops frog, is a species of frog in the family Microhylidae. It is endemic to Halmahera in the Maluku Islands of Indonesia. It is only known from the holotype collected from Galela in 1894. The genus-level placement of this little known frog has changed many times, and it is still unclear whether it should be placed in some other genus.
Chiasmocleis alagoana is a species of frogs in the family Microhylidae. It is endemic to remnants of the Atlantic rainforest in the states of Alagoas, Paraíba, and Pernambuco in north-eastern Brazil. The specific name alagoana refers to Alagoas, the state where this species was first found.
Chiasmocleis anatipes is a species of frog in the family Microhylidae. As currently known, it is endemic to northeastern Ecuador, but it is likely to occur also in adjacent parts of Peru and perhaps Colombia too. The specific name anatipes refers to the "duck-like" feet of this frog, characterized by extensive webbing between the toes. Common name Santa Cecilia humming frog has been proposed for this species.
Ctenophryne minor is a species of frog in the family Microhylidae. It is endemic to Colombia and only known from its type locality in the upper Río Saija drainage, Cauca Department. Common name Colombian egg frog has been coined for it.
Hamptophryne boliviana, also known as the Bolivian bleating frog or Amazon sheep frog, is a species of frogs in the family Microhylidae. It is found in the northern and western sides of the Amazon basin in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Genetic analysis suggests hidden diversity within the nominal species.
Ctenophryne aterrima is a species of frog in the family Microhylidae. It is found in northwestern Ecuador, the Andes of Colombia, and lowland and premontane zones of Panama and Costa Rica to about 1,600 m (5,200 ft) above sea level.
Oreophryne notata is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and known from two localities, Ialibu, its type locality in the Southern Highlands Province, and Tabubil in the Western Province. It might occur more widely. The specific name notata is from Latin nota meaning a "mark" or "letter" and refers to the diagnostic U-like pattern on the lores.
Oreophryne wolterstorffi is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and only known from a single specimen collected from "Deutsch-Neu-Guinea", in what now is Madang Province. Common name Wolterstorff's cross frog has been coined for it.
Copiula alpestris is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and known from the Western Highlands, Chimbu, and Eastern Highlands Provinces at elevations of 1,800–2,800 m (5,900–9,200 ft) above sea level. The specific name is a Latin adjective meaning "living in high mountains", in reference to its relatively high-altitude habitats. Based on molecular evidence, the species was transferred from Oxydactyla to Copiula in 2016.
Chiasmocleis antenori, also known as the Ecuador silent frog, is a species of frog in the family Microhylidae. It is found in eastern Ecuador, eastern Peru, and western Brazil (Acre). It might be a species complex.
Ctenophryne barbatula is a species of frog in the family Microhylidae. It is endemic to Peru and only known from the Yanachaga–Chemillén National Park, its type locality in the Pasco Region.

Pristimantis attenboroughi, also known as Attenborough's rubber frog, is a species of frog in the family Strabomantidae. It is endemic to the Peruvian Andes and has been recorded in and near the Pui–Pui Protection Forest. It is the first amphibian named after David Attenborough. It was discovered by Edgar Lehr and Rudolf von May during a period of two years of studying the forests of Peru. The species description was based on 34 specimens caught at elevations of 3,400–3,936 m (11,155–12,913 ft) above sea level.
