Cruziohyla Sylviae
''Cruziohyla sylviae'', also known as Sylvia's tree frog, is a large colourful species of tree frog from Central America. Description and taxonomy The species was described in 2018 by zoologist Andrew Gray, 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.

Andrew Gray (zoologist)
Andrew Gray is a British zoologist, teacher and conservationist. Biography Andrew Gray was appointed Curator of Herpetology at Manchester Museum in September 1995. Here he established ‘The Vivarium’, a free to the public purpose-built facility dedicated to the conservation of tropical amphibians. Gray's interest in amphibians and reptiles began from a very early age. During his career as a professional herpetologist he has discovered new species and established conservation initiatives to save some of the rarest frogs in the world, for example the critically endangered lemur leaf frog. Gray is an authority on frogs of the Phyllomedusinae genus ''Cruziohyla''. He described the tadpole of ''Cruziohyla calcarifer'' and in 2018 described the new species ''Cruziohyla sylviae'' which is named after his first grandchild Sylvia Beatrice Gray. Gray's conservation efforts have mainly focused in Central America, where he has initiated multi-disciplined collaborative projects, develope ...

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'' †...

Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Cruziohyla Craspedopus
''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. Description Adult males measure and adult females in snout–vent length. The head is slightly wider than it is long. The snout is sharply truncate in lateral view. The fingers and toes are webbed. The hind margin of the tarsus bear extensive dermal appendages forming irregular spurs. The dorsum has uniform dark green dorsal background coloration interspersed with irregular-shaped large pale blue-grey lichenose blotches. The flanks have narrow black lines. The undersides and concealed surfaces of the flanks and legs are yellow. Habitat and conservation ''Cruziohyla craspedopus'' is a high-canopy frog of primary tropical lowland rainforest at elevations of above sea level. It only descends to lower branches for breeding, which takes place in falle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Limón Province
Limón (), commonly known as Puerto Limón, is a district, the capital city and main hub of Limón province, as well as of the Limón canton in Costa Rica. It is the seventh largest city in Costa Rica, with a population of over 55,000, and is home of the Afro-Costa Rican community. Part of the community traces its roots to Italian, Jamaican and Chinese laborers who worked on a late nineteenth-century railroad project that connected San José to Puerto Limón. Until 1948, the Costa Rican government did not recognize Afro-Caribbean people as citizens and restricted their movement outside Limón province. As a result of this "travel ban", this Afro-Caribbean population became firmly established in the region, which influenced decisions not to move even after it was legally permitted. Nowadays, there is a significant outflow of Limón natives who move to the country's Central Valley in search for better employment and education. The Afro-Caribbean community speaks Spanish and Limones ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 2018
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 ...

Cruziohyla
''Cruziohyla'' is a genus of frogs in the subfamily Phyllomedusinae. They occur from Nicaragua and 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''. These frogs are characterized by extensive hand and foot webbing. Their eye has a bicoloured iris. Tadpoles develop in water-filled depressions on fallen trees. The name ''Cruziohyla'' honors Brazilian herpetologist Carlos Alberto Gonçalves da Cruz. Species There are three ''Cruziohyla'' species: * ''Cruziohyla calcarifer'' (Boulenger, 1902) — splendid leaf frog * ''Cruziohyla craspedopus'' (Funkhouser, 1957) — fringe tree frog * ''Cruziohyla sylviae ''Cruziohyla sylviae'', also known as Sylvia's tree frog, is a large colourful species of tree frog from Central America.
