New species of skink discovered on Socotra Archipelago

Unique biodiversity
May 2012. The Socotra Archipelago, in the north-west Indian Ocean off the coast of Somalia, is considered to be one of the most biodiversity rich group of islands in the world, thanks to a very distinct fauna and flora with a high level of endemicity at both species and generic levels. 

UNESCO World Heritage Site
For this reason, it has been designated as UNESCO World Heritage Natural site in 2008. Nevertheless, the natural history of most groups is still not clear, and their origin and evolution remain unknown. 

A team of researchers from the Department of Animal Biology (Universit√† di Pavia, Italy), the Institute of Evolutionary Biology (CSIC-UPF, Barcelona, Spain), the Museo Civico di Storia Naturale di Carmagnola (Italy) and the Museum of Science of Trento (Italy), have been investigating the herpetofauna of the archipelago since 2007, in the framework of the ‘Socotra Conservation and Development Project' funded by the Cooperazione Italiana and under the auspices of the United Nations Development Project (UNDP) to collect ecological data on the reptiles of the Socotra Archipelago in order to improve the sustainable development and conservation of the Socotra Archipelago's biodiversity.

In a recent paper, the team presented some new highlights on the systematics, biogeography and evolution of Trachylepis socotrana, the only endemic reptile (a skink) supposed to live in all four islands (Socotra, Darsa, Samha and Abd Al Kuri). By comparing the skinks of the archipelago with representatives of the genus Trachylepis from Middle East, Africa and Madagascar plus some individuals from each of the other three genera of Mabuya skinks sensu lato (Chioninia, Eutropis and Mabuya), they have been able to trace back the history of the Socotran skinks.
