Gymnodactylus is a genus of gecko-like (Gekkota). This genus used to be directly part of the gecko family(Gekkonidae), but wasspun offtogether with other genera in a separate family Phyllodactylidae in2008. Gymnodactylus species are endemic to Brazil .
features
The name of the family Phyllodactylidae means "leaf finger" and is composed of the two Greek terms phyllos ( Greek φύλλος ) for "leaf" and dactylos (δάκτυλος) for "finger". This name refers to a prominent feature of some genera of these geckos, namely the widened sticky toes and fingers, for example in the genus fan finger ( Ptyodactylus ). The generic name Gymnodactylus indicates the opposite and means “naked finger” from gymnos (γυμνος) “naked” and dactylos for “finger”.
The head-trunk length of the species from the genus Gymnodactylus is 3 to 5 centimeters, the tail length 3 to 7 centimeters.
distribution
Gymnodactylus belongs to the Neotropical genera of the Phyllodactylidae family. It is known from the Brazilian ecoregions Cerrado , Caatinga and the Atlantic Rainforest .
Taxonomy and systematics
The species Gymnodactylus vanzolinii was described in 2009 as the last of the genus to date. Previously, specimens of this lizard from the northern part of the Serra do Espinhaço were kept for the southern expression of Gymnodactylus geckoides , the type species of the genus Gymnodactylus . Johann Baptist von Spix had brought a specimen of Gymnodactylus geckoides from his trip to Brazil on behalf of the King of Bavaria in the years 1817 to 1820 and described it in 1825, shortly before his untimely death.
species
Six types have been described:
- Gymnodactylus amarali Barbour, 1925, is only known from one specimen from Engenheiro Dodt , state of Piauí and one juvenile specimen from Alto Parnaíba state of Maranhão , both in the Cerrado.
- Gymnodactylus carvalhoi Vanzolini, 2005 is widespread in the Cerrado.
- Gymnodactylus darwinii (Gray, 1845) has so far only been found in the Atlantic rainforests of Brazil, from the northeast of the state of São Paulo to the state of Rio Grande do Norte .
- Gymnodactylus geckoides Spix, 1825 is endemic to the Caatinga in northeastern Brazil, but also occurs, together with Gymnodactylus darwinii, in the dune landscape around Natal , the capital of the state of Rio Grande do Norte.
- Gymnodactylus guttulatus Vanzolini, 1982 is only known from the rock grass in the south of the Serra do Espinhaço, a mountain range in the states of Minas Gerais and Bahia .
- Gymnodactylus vanzolinii Cassimiro & Rodrigues, 2009 is so far only known from the Serra do Sincorá , an area in the north of the Serra do Espinhaço with an altitude of up to more than 2000 meters.
