New Record of the Leopard Gecko Goniurosaurus araneus (Squamata: Eublepharidae) for China and Habitat Partitioning between Geographically and Phylogenetically Close Leopard Geckos

Abstract

Two specimens of the Leopard Gecko Goniurosaurus araneus (Squamata: Eublepharidae) were collected from Nonggang National Nature Reserve, Chongzuo Prefecture, Guangxi Zhuang Ethnicity Autonomous Region, China, in October 2011. This species is a new record for China and this report is a range extension for the species from northern Vietnam to southern Guangxi. A phylogenetic study demonstrated that Goniurosaurus araneus and G. luii are a species pair. We show for the first time that they coexist broadly but are narrowly allopatric in a small area in southern Guangxi, separated only by a river, similar to what had been reported previously for G. yingdeensis and Goniurosaurus indet. from northwestern Guangdong. A river as a geographical barrier, elevation, and aspect may have contributed to habitat partitioning between G. araneus and G. luii.
