Mantellinae
Mantellinae is a subfamily of frogs in the family Mantellidae. These frogs are native to Madagascar and Mayotte. The species vary in size from under 25 mm (e.g. some species of ''Blommersia'') to over 100 mm (e.g. ''Mantidactylus guttulatus''). The subfamily is most famous for the genus ''Mantella'', which contains species that superficially resemble poison dart frogs of the tropical Americas, and have converged on similar aposematic colouration and toxins. As of 2 May 2016, there are 128 described species in this subfamily, but several more are described each year. Systematics Historically only two genera were recognized within the Mantellinae: ''Mantella'' and ''Mantidactylus''. Several subgenera were recognized within the genus ''Mantidactylus''. These were elevated to genus level in 2006 and are now universally accepted. These are ''Blommersia'', ''Boehmantis'', '' Gephyromantis'', '' Guibemantis'', ''Spinomantis ''Spinomantis'' is a frog genus in the mantell ...

Boehmantis
''Boehmantis'' is a genus of frogs in the mantellid subfamily Mantellinae. It is monotypic, being represented by a single species, ''Boehmantis microtympanum''. The genus is endemic to Madagascar. Taxonomy ''Boehmantis microtympanum'' was originally described in the genus ''Mantidactylus'' by Fernand Angel. The species was transferred to its own genus, ''Boehmantis'', by Frank Glaw and Miguel Vences. This was justified using molecular data as well as by the lack of femoral glands, which are present in all other species in the subfamily Mantellinae. Etymology The generic name honours , German herpetologist. Description ''Boehmantis microtympanum'' are relatively large frogs, with adults measuring in snout–vent length. The tympanum is rather indistinct and small. The finger and toe tips bear well-developed discs; the fingers have no webbing whereas the toes are fully webbed. Dorsal skin is smooth. The dorsal colouration varies from olive greenish to—especially in subadults� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gephyromantis
''Gephyromantis'' is a frog genus in the mantellid subfamily Mantellinae. This genus is restricted to Madagascar. At present it contains 45 species divided into six subgenera. Taxonomy The genus ''Gephyromantis'' was erected by Methuen in 1920 for the species '' Gephyromantis boulengeri''. Blommers-Schlösser considered this group as a subgenus of ''Mantidactylus'', but it was re-elevated to genus-level in 2006. Species This genus is divided into six subgenera: * ''Gephyromantis'' Methuen, 1920 :* '' Gephyromantis blanci'' Guibé, 1974 :* '' Gephyromantis boulengeri'' Methuen, 1920 :* '' Gephyromantis verrucosus'' Angel, 1930 :* '' Gephyromantis leucocephalus'' Angel, 1930 :* '' Gephyromantis decaryi'' Angel, 1930 :* '' Gephyromantis hintelmannae'' Wollenberg, Glaw, and Vences, 2012 :* ''Gephyromantis enki'' (Glaw and Vences, 2002) :* ''Gephyromantis eiselti'' Guibé, 1975 :* ''Gephyromantis thelenae'' (Glaw and Vences, 1994) :* '' Gephyromantis mafy'' Vieites, Wollenberg, and ...

Spinomantis
''Spinomantis'' is a frog genus in the mantellid subfamily Mantellinae. This genus is restricted to Madagascar. At present it contains 13 species. They are arboreal or terrestrial frogs and occur in or along small streams. Most species are nocturnal. Taxonomy The genus ''Spinomantis'' was erected as a subgenus of ''Mantidactylus'' by Dubois in 1992. It was elevated to genus-level in 2006. Description ''Spinomantis'' are small to medium-sized frogs, with adults measuring in snout–vent length. The toes have rudimentary to moderate webbing. The finger tips are distinctly enlarged. Males have subgular vocal sac The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way o ...s.

Guibemantis
''Guibemantis'' is a frog genus in the mantellid subfamily Mantellinae. This genus is restricted to Madagascar. At present it contains 16 species divided into two subgenera. Taxonomy The genus ''Guibemantis'' was erected as a subgenus of ''Mantidactylus'' by Dubois in 1992 with the type species '' Guibemantis depressiceps''. It was elevated to genus-level in 2006. In 1994, the subgenus '' Pandanusicola'' was erected for a group of species that are strongly associated with Pandanus screw-palms. It was originally proposed as an additional subgenus of ''Mantidactylus'', but when ''Guibemantis'' was elevated to genus-level in 2006, ''Pandanusicola'' was made a subgenus of it.

Mantella
''Mantella'' (also known as golden frogs or Malagasy poison frogs) are a prominent genus of aposematic frogs in the family Mantellidae, endemic to the island of Madagascar. Members of ''Mantella'' are diurnal and terrestrial, with bright aposematic coloration or cryptic markings. Natural history ''Mantella'' are an example of convergent evolution—the independent evolution of a similar trait with species of a different lineage—with the Latin American family Dendrobatidae in size, appearance, and some behavioral characteristics. During the description of the first specimens from 1866 to 1872, Alfred Grandidier described both the brown mantella (''Mantella betsileo'') and Malagasy mantella (''Mantella madagascariensis'') and placed them within the genus ''Dendrobates'' based on their close resemblance. This placement was heavily debated until 1882, when George Albert Boulenger created the genus ''Mantella'' after describing both Cowan's mantella (''Mantella cowanii ...

Mantidactylus
''Mantidactylus'' is a frog genus in the mantellid subfamily Mantellinae. This genus is restricted to Madagascar. The genus is divided into several subgenera that form monophyletic genetic clusters and are ecologically similar. Taxonomy ''Mantidactylus'' was erected by Boulenger in 1895 with the type species '' Rana guttulata''. For a long time the genus contained a wide variety of mostly terrestrial Madagascan frogs, that were divided into species groups and/or subgenera. Several of these groups were subsequently erected to genus level: ''Blommersia'', ''Boehmantis'', '' Gephyromantis'', '' Guibemantis'', ''Spinomantis'' and '' Wakea''. Today, six subgenera remain within the genus ''Mantidactylus'': *''Mantidactylus'' Boulenger, 1895 *'' Hylobatrachus'' Laurent, 1943 *'' Brygoomantis'' Dubois, 1992 *'' Ochthomantis'' Glaw & Vences, 1994 *'' Chonomantis'' Glaw & Vences, 1994 *'' Maitsomantis'' Glaw & Vences, 2006 Species New species of ''Mantidactylus'' are described at ...

Mantellidae
The Mantellidae are a family of the order Anura. These frogs are endemic to the islands of Madagascar and Mayotte. Systematics The family Mantellidae is composed of three extremely ecologically diverse groups of frogs, divided into three subfamilies: the Mantellinae Laurent, 1946 are typically terrestrial or semi-aquatic frogs; the Laliostominae Vences & Glaw, 2001 are terrestrial, typically fairly large-sized frogs; and the Boophinae Vences & Glaw, 2001 are arboreal tree frogs. Apart from the genera assigned to the three subfamilies, the placement of '' Tsingymantis'' Glaw, Hoegg & Vences, 2006 is still uncertain. As of 22 September 2022, 237 species are recognized in this family. DNA barcoding research has shown however that more than 100 distinct genetic lineages remain taxonomically undescribed. Evolution and island biogeography The Mantellidae are Madagascar's most diverse frog family. It has been shown that there is a negative correlation between body size ...

Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy. The recurrent evolution of flight is a classic example, as flying insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas ''homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different traits. Convergent evolution is similar to paralle ...

Americas
The Americas, which are sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with their associated islands, the Americas cover 8% of Earth's total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon, St. Lawrence River– Great Lakes basin, Mississippi, and La Plata. Since the Americas extend from north to south, the climate and ecology vary widely, from the arctic tundra of Northern Canada, Greenland, and Alaska, to the tropical rain forests in Central America and South America. Humans first settled the Americas from Asia between 42,000 and 17,000 years ago. A second migration of Na-Dene speakers followe ...
