Amalosia is a tree-dwelling genus of gecko-like from the family of the double- fingered geckos (Diplodactylidae). It isnativeto Australia .

features

The species of this genus reach a head-trunk length of a maximum of 63 millimeters. This makes them one of the relatively small geckos. The animals are mostly gray-violet to red-brown in color, sometimes with dark transverse bands, but these can vary within the same species. The back scales are smaller than the ventral scales . The adhesive lamellas on the feet are widened.

distribution

The genus is only common in the southeast and southwest of Australia. It lives on trees and is therefore, unlike some other genera of the double-fingered geckos, dependent on wooded areas of Australia.

Systematics

In their work A synopsis of the class Reptilia in Australia , published in 1983, Wells and Wellington proposed that four smaller species of the genus Oedura should be separated as a separate genus Amalosia . The work was controversial and hardly implemented by the scientists studying Australia's geckos. In 2012, after molecular genetic studies by Oliver et al. the view of Wells and Wellington with regard to the genus Amalosia largely confirmed, since three of the four species they identified could be combined as a separate clade . However, Oedura reticulata was not placed in the genus Amalosia , as suggested by Wells and Wellington , but as the only species in the newly established monotypical genus Hesperoedura . The species Oedura jacovae , which was newly described in 2007, was also placed in the genus Amalosia due to morphological similarities .

The genus Amalosia currently comprises four species.
