Stefania
''Stefania'' is a genus of frogs in the family Hemiphractidae. They are native to the highlands of the Guiana Shield in southern Venezuela, Guyana, and adjacent far northern Brazil. Most are restricted to the tepui highlands, but '' S. evansi'' also occurs in lowlands. On most mountains there are only 1–2 species from this genus, but five are known from Mount Ayanganna and the neighbouring Mount Wokomung has six species. They are usually found near streams at low levels on branches/leaves or on the ground among vegetation/rocks. They are famous for their breeding strategy where the development from eggs to froglets is completed on the back of the female (the eggs hatch to froglets; there is no free-swimming tadpole A tadpole or polliwog (also spelled pollywog) is the Larva, larval stage in the biological life cycle of an amphibian. Most tadpoles are fully Aquatic animal, aquatic, though some species of amphibians have tadpoles that are terrestrial animal, ... stage). Th ...

Frog
A frog is any member of a diverse and largely semiaquatic group of short-bodied, tailless amphibian vertebrates composing the order (biology), order Anura (coming from the Ancient Greek , literally 'without tail'). Frog species with rough skin texture due to wart-like parotoid glands tend to be called toads, but the distinction between frogs and toads is informal and purely cosmetic, not from taxonomy (biology), taxonomy or evolutionary history. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest and associated wetlands. They account for around 88% of extant amphibian species, and are one of the five most diverse vertebrate orders. The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar (250Myr, million years ago), but molecular clock, molecular clock dating suggests their divergent evolution, divergence from other amphibians may exte ...

Cryptobatrachus
''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''. Description ''Cryptobatrachus'' have a treefrog-like habitus. Males measure and females in snout–vent length. Fingers have no webbing whereas the toes are webbed. The finger and toe tips bear disks that are larger on the former. Also adhesive pads are present on the penultimate subarticular tubercles on the fingers. Males lack vocal sac and these frogs appear not to vocalize. Species There are six species in the genus ''Cryptobatrachus'': * '' Cryptobatrachus boulengeri'' Ruthven, 1916 * '' Cryptobatrachus conditus'' Lynch, 2008 * '' Cryptobatrachus fuhrmanni'' (Peracca, 1914) * '' Cryptobatrachus pedroruizi'' Lynch, 2008 * '' Cryp ...

Hyloidea
Hyloidea is a superfamily of frogs.R.Alexander Pyron, John J.Wiens, 2011, ''A large-scale phylogeny of Amphibia including over 2800 species, and a revised classification of extant frogs, salamanders, and caecilians'' Hyloidea accounts for 54% of all living anuran species. The superfamily Hyloidea branched off from its closest relative, the Australobatrachia, during the mid-Cretaceous. The fossil evidence found during the Cretaceous-Paleogene extinction event could not determine the effects upon the frogs, due to the lack of fossils. Increased forestation erupted after this extinction, possibly leading to more arboreal adaptations of these anurans to be best suited for this habitat. Taxonomy Hyloidea contains the following subgroups: * Allophrynidae – Tukeit Hill frogs (3 species) * Alsodidae – (26 species) *Batrachylidae – (14 species) *Bufonidae – true toads and harlequin frogs (700 species) *Brachycephaloidea **Brachycephalidae – saddleback toads, flea toads an ...
