Josefa Celsa Señaris
Josefa Celsa Señaris (born 2 November 1965) is a Venezuelan herpetologist. She has published information about frogs and she has identified new genera and species. Señaris is the director of the La Salle Foundation's Natural History Museum (Spanish: ''Museo de historia natural La Salle - MhnLS'') in Caracas. Life Señaris was born in 1965 and she obtained a degree in biology at the Central University of Venezuela and her doctorate in 2001 at the University of Santiago de Compostela in Spain. She is interested in the fauna of Venezuela, in particular the Guayana Region where table-top mountains called tepuis provide habitats for endemic plant and animal species: some amphibians are known only from a single tepuy. From a geological point of view, the tepuis have been isolated for approximately 120 million years, and it has been suggested that the tepuy habitats are a "lost world" that could support relictual populations.

Caracas
Caracas (, ), officially Santiago de León de Caracas, abbreviated as CCS, is the capital and largest city of Venezuela, and the center of the Metropolitan Region of Caracas (or Greater Caracas). Caracas is located along the Guaire River in the northern part of the country, within the Caracas Valley of the Venezuelan coastal mountain range (Cordillera de la Costa). The valley is close to the Caribbean Sea, separated from the coast by a steep 2,200-meter-high (7,200 ft) mountain range, Cerro El Ávila; to the south there are more hills and mountains. The Metropolitan Region of Caracas has an estimated population of almost 5 million inhabitants. The center of the city is still ''Catedral'', located near Bolívar Square, though some consider the center to be Plaza Venezuela, located in the Los Caobos area. Businesses in the city include service companies, banks, and malls. Caracas has a largely service-based economy, apart from some industrial activity in its metropolitan ar ...

Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Hyalinobatrachium Mondolfii
''Hyalinobatrachium mondolfii'' is a species of frog in the family Centrolenidae from northern South America. Distribution Its distribution is poorly known but has two main areas: western Amazonian basin in Leticia in southeastern Colombia, Acre in western Brazil, and Pando Department in northern Bolivia, and the Guiana Shield region in Pará in northern Brazil, southern Suriname, Guyana, and Delta Amacuro and Monagas states in northeastern Venezuela. It is very similar to ''Hyalinobatrachium munozorum'' and ''Hyalinobatrachium ruedai'', and it may be impossible to distinguish these species on the basis of morphological characteristics alone. Description ''Hyalinobatrachium mondolfii'' has snout that is rounded in dorsal and lateral view. The tympanumic membrane is not visible. The belly and parietal peritoneum are transparent, whereas pericardium The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessel ...

Hyalinobatrachium Guairarepanense
''Hyalinobatrachium guairarepanense'' is a species of frog in the family Centrolenidae. It is endemic to Venezuela, where it is found in locations in the Coastal Range at elevations between above sea level. Its natural habitats are seasonal ( semi-deciduous) forests where it occurs along streams. The eggs are laid on leaves overhanging a stream to which the hatched larvae drop and where they continue their development. It is threatened by habitat loss. However, it has declined also in pristine habitats, suggesting that chytridiomycosis (or other disease) may be at play. Its range includes the El Ávila National Park and the Macarao National Park The Macarao National Park ( es, Parque nacional Macarao) Is a protected area with the status of a national park located in the Macarao, San Pedro and Jarillo rivers, in the north of the South American country of Venezuela.

Taxon
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 Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celsiella
''Celsiella'' is a small genus of glass frogs endemic to Venezuela. It was established in 2009 and named in honour of Josefa Celsa Señaris, nicknamed "Celsi", a Venezuelan herpetologist who had worked with glass frogs. Description The ventral parietal peritoneum is white anteriorly and transparent posteriorly. The bones are pale green or green. Male ''Celsiella'' call from, and females deposit their eggs on the underside or upper side of leaves. Tentative evidence suggests that males guard their eggs. Taxonomy Monophyly of ''Celsiella'' is strongly supported by genetic data. It is also morphologically distinct from the closely related genus ''Hyalinobatrachium''species of which have completely transparent venters, white liver, and white bones. It was erected in 2009; its species composition has not changed afterwards. Species There are two species: * ''Celsiella revocata ''Celsiella revocata'' is a species of frog in the family Centrolenidae. It is endemic to the Venezuel ...
