Stumpffia Analanjirofo
''Stumpffia'' is a genus of microhylid frogs that are endemic to Madagascar. They are mostly brown frogs that typically live among leaf litter. ''S. contumelia'' has a snout–vent length of about , making it one of the world's smallest frogs, and several others in the genus are only slightly larger. The largest species is no more than . The majority of the species have only been described since 2010. Each species has a small range and many are seriously threatened. Taxonomy ''Stumpffia'' was first described from the single species '' Stumpffia psologlossa'' Boettger, 1881, based on a single specimen collected on Nosy Be, a large island off the northwest coast of Madagascar, by Antonio Stumpff. By 2017, 15 species were recognised. In late 2017, a major revision of the genus was published. This study used integrative taxonomy, i.e. the combination of multiple different datasets, to delimit and describe new species: it combined morphological, morphometric, chromatic (color), ...

Oskar Boettger
Oskar Boettger (; 31 March 1844 – 25 September 1910) was a German zoologist who was a native of Frankfurt am Main. He was an uncle of the noted malacologist Caesar Rudolf Boettger (1888–1976). From 1863 to 1866 he studied at the Bergakademie Freiberg, then worked for a year in a chemical factory in Frankfurt am Main."Boettger, Oskar" p. 410. In: (1955). ''Neue Deutsche Biographie (NDB). Band 2''. Berlin: Duncker & Humblot. . (in German). In 1869 he received his doctorate from the University of Würzburg. The following year (1870), he became a paleontologist at the Senckenberg Museum in Frankfurt, where in 1875 he became the curator of the museum's department of herpetology. He is credited for making Senckenberg's herpetological collection among the best in Europe. Boettger had agoraphobia and rarely left home, never setting fo ...

Monophyly
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A ''polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andolalao Rakotoarison
Andolalao Rakotoarison (born 1982 in Mahajanga) is a Malagasy herpetologist. Life and research Rakotoarison conducted her Master's thesis at the University of Antananarivo in 2011. She then conducted her PhD at the Technical University of Braunschweig on the systematics of the frogs of the Madagascar-endemic narrow-mouthed frog subfamily Cophylinae, under the supervision of Professor Miguel Vences. As of mid-2020, she has co-authored the description of 52 frog species and two reptiles (one gecko and one chameleon). In particular, Rakotoarison has contributed to knowledge of Madagascar's smallest frogs. In 2017, she led a study published as a monograph with sixteen other coauthors, describing 26 new species of the genus '' Stumpffia'', including several frogs that number among the smallest in the world, and in 2020, she was also involved in the description of five more miniaturised frogs, including the new genus ''Mini'' and its three diminutive species.

Mini (frog)
''Mini'' is a genus of tiny microhylid frogs that are endemic to southeastern Madagascar where they live among leaf litter in lowland forests. The three species and the genus itself were only scientifically described in 2019; although not yet rated by the IUCN, they have very small ranges and it has been recommended that two qualify as critically endangered and ''M. ature'' as data deficient. At about in snout–vent length, ''M. mum'' and ''M. scule'' are two of the world's smallest frogs, and the larger ''M. ature'' is only . They were formerly confused with ''Stumpffia'', another genus of tiny frogs from Madagascar. All are well-camouflaged brown frogs. Species The genus name is derived from English prefix "mini-", denoting a small version of an object. All the binomials names are examples of wordplay as they sound like words for small in English. There are currently 3 species: * ''Mini ature ''Mini ature'' is a species of very small microhylid frog endemic to Madag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...
