Atlantihyla
''Atlantihyla'' is a genus of frogs in the family Hylidae. It is endemic to Central America, specifically to Honduras and Guatemala. The generic name refers to its distribution on the Atlantic side of the isthmus (from ''Atlantis''+''hyla''). The members of the genus are known as stream frogs. Taxonomy The genus was established based on molecular data in a revision of the subfamily Hylinae by Julián Faivovich and colleagues in 2018. In order to obtain a monophyletic '' Ptychohyla'', Faivovich and colleagues moved two former ''Ptychohyla'' species to ''Atlantihyla'' and four former ''Ptychohyla'' species to '' Quilticohyla.'' ''Atlantihyla'' has a sister group relationship to a poorly-supported clade that includes ''Bromeliohyla'', '' Duellmanohyla'', and ''Quilticohyla''. A third ''Atlantihyla'' species was described in 2020. Description The only, tentative phenotypic synapomorphy of this genus is the presence of a well-defined ventrolateral white stripe. A vertical rostra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guatemala Stream Frog
''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 , an American herpetologist. Description Adult males measure and adult females, based on a single specimen, in snout–vent length. The snout is rounded but has a pointed tip in dorsal view because of a vertical rostral keel. The tympanum is round but its upper edge is obscured by the heavy supratympanic fold. The fingers bear large discs and are up to about half webbed. The toes are almost fully webbed and bear discs somewhat smaller than the fingers ones. The dorsal ground color is grayish tan with green flecks (especially prominent on the eyelids, sometimes completely ringed by them) and darker brown mottling, or dark brown with darker gray brown markings. There is a white stripe on the edge of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hylidae
Hylidae is a wide-ranging family of frogs commonly referred to as "tree frogs and their allies". However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Taxonomy and systematics The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. The common name of "tree frog" is a popular name for several species of the family Hylidae. However, the name "treefrog" is not unique to this family, also being used for many species in the family Rhacophoridae. The following genera are recognised in the family Hylidae: * Subfamily Hylinae ** Tribe Cophomantini *** '' Aplastodiscus'' – canebrake treefrogs *** ''Boana'' – gladiator treefrogs *** ''Bokermannohyla'' *** ''Hyloscirtus'' *** ''Myersiohyla'' *** ''Nesorohyla'' *** '' "Hyla" nicefori'' ** Tribe Dendropsophini ***''Dendropsophus'' *** '' Julianus'' *** ''Lysapsus'' †...

Hylinae
Hylinae is a large subfamily of "tree frogs", family Hylidae. Classification The contents of this subfamily vary substantially according to the source. The Amphibian Species of the World follows the revision by Duellman and colleagues from 2016 based on molecular data and delimits the subfamily more narrowly than before, treating parts of former Hylinae as their own subfamilies. Following this classification, there were 18 genera totaling 174 species in the end of 2020. They are found North, Central, and the northmost South America, much of temperate Eurasia, Japan, and extreme northern Africa, however, only ''Hyla'' is found outside the Americas. The Wikipedia is following this classification. The AmphibiaWeb follows an older classification defining Hylinae more broadly, with several hundred species. At the end of 2020, the AmphibiaWeb lists 42 genera totaling 737 species. Amphibian Species of the World At the end of 2020, the Amphibian Species of the World includes the follo ...

Synapomorphy
In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor. ) In cladistics, synapomorphy implies homology. Examples of apomorphy are the presence of erect gait, fur, the evolution of three middle ear bones, and mammary glands in mammals but not in other vertebrate animals such as amphibians or reptiles, which have retained their ancestral traits of a sprawling gait and lack of fur. Thus, these derived traits are also synapomorphies of mammals in general as they are not shared by other vertebrate animals. Etymology The word —coined by German entomologist Willi Hennig—is derived from the Ancient Greek words (''sún''), meaning "with, together"; (''apó''), meaning "away from"; and (''morphḗ''), meaning "shape, form".

Taxa Named By Darrel Frost
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphibians Of Central America
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...
