Cruziohyla sylviae, also known as Sylvia's tree frog, is a large colourful species of tree frog from Central America. [2] [3] People have seen it between 30 and 1600 meters above sea level. [1]
The species was described in 2018 by zoologist Andrew Gray, [4] and is named after his granddaughter. It can be distinguished from the closely related C. calcarifer (Splendid Tree Frog) by having small green lichen-like markings on its dorsal surfaces rather than white or pale blue spots and lacking characteristic dark ventral markings found on the under-thighs of C. calcarifer which are characteristic of only that species of Cruziohyla. The species is also easily identified by having a large external eardrum (tympanum), which is almost the same size as the eye, compared to an eardrum half its size, as seen in C. calcarifer. DNA analysis places C. sylviae genetically closer to its sister species, C. craspedopus , than to the true C. calcarifer described by George A. Boulenger in 1902. [4] The adult male frog measures 44.3 to 67.0 mm in snout-vent length and the adult female frog 73.5 to 88.2 mm. [3]
C. sylviae occurs from Panama to Honduras, where it lives in primary forest. The type locality for the species is Guayacán in Limón province of Costa Rica. Until 2018 the species was confused with the splendid tree frog ( C. calcarifer ), which occurs from Ecuador to Costa Rica. [4]
This frog lives high in the canopy in forests and flood plains. It descends to lower branches to breed. The female frog lays eggs in water collected in dead trees. People have also seen tadpoles in reservoirs with trees nearby, suggesting that tree cover is more relevant to this frog's survival than undisturbed habitat. [1]
The northern sheep frog is native to Central America, Mexico, and extreme south Texas, United States. It occurs in the lowlands from Sonora, Mexico, to northern Costa Rica on the Pacific coast, and south Texas to Honduras on the Gulf of Mexico and Caribbean coasts. The sheep frog inhabits semiarid thornscrub, savannas, pasturelands, and open woodlands, as well as more humid, moist forest in the canyons, basins, foothills, and lower elevations of mountains slopes. It is a fossorial, burrowing frog that is seldom seen on the surface except at night after heavy rains when they emerge to breed. The sheep frog gets its name from its distinctive call that resembles a sheep's bleat. It is a diet specialist primarily feeding on termites and ants.
Cruziohyla is a genus of frogs in the subfamily Phyllomedusinae. They occur from Honduras in Central America south to the Amazon Basin in South America. This genus was erected in 2005 following a major revision of the Hylidae and fully reviewed in 2018. Species in this genus were previously placed in the genera Agalychnis or Phyllomedusa.
The Panamanian golden frog, also known as Cerro Campana stubfoot toad and other names, is a species of toad endemic to Panama. Panamanian golden frogs inhabit the streams along the mountainous slopes of the Cordilleran cloud forests of west-central Panama. While the IUCN lists it as Critically Endangered, it may in fact have been extinct in the wild since 2007. Individuals have been collected for breeding in captivity in a bid to preserve the species. The alternative common name, Zetek's golden frog, and the epithet zeteki both commemorate the entomologist James Zetek.
Wallace's flying frog, also known as the gliding frog or the Abah River flying frog, is a moss frog found at least from the Malay Peninsula into western Indonesia, and is present in Borneo and Sumatra. It is named for the biologist, Alfred R. Wallace, who collected the first known specimen.
Atelopus senex is an extinct species of toad in the family Bufonidae. It was endemic to Costa Rica and known from the Cordillera Central and Cordillera de Talamanca at elevations of 1,100–2,200 m (3,600–7,200 ft) asl.
Sachatamia ilex is a species of frog in the family Centrolenidae. It is found in eastern Nicaragua, Costa Rica, Panama, western Colombia, and western Ecuador. Common name Limon giant glass frog has been coined for this species, apparently in reference to its type locality in the canton of Limón, Costa Rica, and it is also known as the ghost glass frog.
Teratohyla spinosa is a species of frog in the family Centrolenidae. It is found in the Pacific lowlands of northern and central Ecuador and western Colombia, northward on the Pacific slopes Panama and Costa Rica, as well as on the Caribbean slopes of Costa Rica, Nicaragua, and Honduras.
Hyalinobatrachium chirripoi is a species of frog in the family Centrolenidae. It is found in extreme northern Ecuador, northwestern Colombia, Panama, and Costa Rica, as well as in Honduras. The specific name chirripoi refers to the Chirripó Indians inhabiting the area of the type locality, Suretka in the Talamanca canton of Costa Rica. The common name Suretka glass frog has been coined for it.
The powdered glass frog or Chiriqui glass frog is a frog species in the glass frog family (Centrolenidae). The species is found from north-central Honduras south to northwestern Ecuador.
Agalychnis saltator, also known as the parachuting red-eyed leaf frog and misfit leaf frog, is a species of frog in the subfamily Phyllomedusinae. It is found in the Caribbean lowlands from north-eastern Honduras to eastern-central Costa Rica at elevations of 15–1,300 m (49–4,265 ft) asl.
Cruziohyla craspedopus, the fringed leaf frog or fringed tree frog, is a species of frog in the subfamily Phyllomedusinae. It is found in the Amazonian lowlands in Brazil, Colombia, Ecuador, and Peru, and possibly in Bolivia.
Agalychnis lemur, the lemur leaf frog or lemur frog, is a species of frog in the subfamily Phyllomedusinae. It is found in Costa Rica, Panama, and adjacent northwestern Colombia. It is classed as Critically Endangered and threatened by the fungal disease chytridiomycosis.
The Veragua cross-banded tree frog is a species of frog in the family Hylidae found in Colombia, Costa Rica, Honduras, Nicaragua, and Panama. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, plantations, rural gardens, urban areas, heavily degraded former forests, and canals and ditches. Scientists have observed it as high in the hills as 1525 meters above sea level.
Pristimantis inguinalis is a species of frog in the family Strabomantidae. It is found in Guyana, Suriname, French Guiana, and northern Brazil. The type locality is New River, in the disputed area claimed by both Guyana and Suriname. Common names New River robber frog and New River South American rain frog have been coined for it.
Megophrys parallela is a species of frog in the family Megophryidae. It is endemic to Sumatra and known from a number of localities on mountains along the island's western coast where it is expected to have a wide distribution.
Polypedates otilophus is a species of frog in the family Rhacophoridae. It is endemic to Borneo where it is widespread and found in Brunei, Indonesia, and Malaysia, typically in the lowlands but sometimes as high as 1,100 m (3,600 ft) above sea level. This species has prominent, sharp ridges behind the eye, above the ear, referred to in its names.
Cruziohyla calcarifer, the splendid leaf frog or splendid treefrog, is a species of tree frog of the subfamily Phyllomedusinae described in 1902 by George Albert Boulenger. It has a distribution from Esmeraldas Province in northwestern Ecuador, through western Colombia and Panama to the most southerly part of Costa Rica. It is a nocturnal, arboreal frog inhabiting primary humid lowland forest. The tadpole of this species was described in 2021
Hylodes fredi is a species of frog in the family Hylodidae, endemic to the island of Ilha Grande, Brazil.
