''Christinus marmoratus'' (synonym: ''Phyllodactylus marmoratus'') is a species of Gekkonidae (gecko) native to southern mainland of Australia, from Victoria to Western Australia. The species is well adapted to a variety of habitats, including city dwellings. Other related taxa in addition to this species are also known as Marbled Gecko. ==Taxonomy== The species was first formally described by John Edward Gray in 1845.〔Gray, J. E. 1845. Catalogue of the specimens of lizards in the collection of the British Museum. Trustees of die British Museum/Edward Newman, London: xxvii + 289 pp.〕 The name he gave placed this group in the genus ''Diplodactylus'' as ''Diplodactylus marmoratus''. Gray's description was based on four specimens that were preserved in spirits. They were collected on the Abrolhos islands (off Western Australia), and were donated to the British museum from the collection of a “Mr. Gilbert.” Gray examined another preserved specimen of ''D. marmoratus'' (from a different donor) which was discoloured, leading him to mistakenly describe it as a separate species (''Goniodactylus australis'') in the same publication. In 1885 Boulenger placed ''D. marmoratus'' in the genus ''Phyllodactylus'' (the leaf-toed geckos).〔Boulenger GA. 1885. Catalogue of the Lizards in the British Museum (Nat. Hist.) I. Geckonidae, Eublepharidae, Uroplatidae, Pygopodidae, Agamidae. London: 450 pp.〕 It remained in that genus until 1984, when a revision by Wells and Wellington placed it in the genus ''Christinus''.〔Wells RW, Wellington CR. 1985. A classification of the Amphibia and Reptilia of Australia. Australian Journal of Herpetology, Supplementary Series 1:1-61.〕 A study conducted by King in 1977 showed that ''C. marmoratus'' exhibits considerable geographic variation in karyotype across its range.〔King M. 1977. Chromosomal and morphometric variation in the gekko Diplodactylus vittatus (Gray). Australian Journal of Zoology 25:43–57.〕 Further investigation by Donnellan et al. (2000) led to the species being recognized as a composite of two subspecies; ''C. marmoratus marmoratus'' and ''C. marmoratus dactylus''.〔Donnellan SC, Aplin KP, Dempsey PJ (2000). Genetic and morphological variation in Australian Christinus (Squamata : Gekkonidae): preliminary overview with recognition of a cryptic species on the Nullarbor Plain. Australian Journal of Zoology 48:289–315.〕 The two subspecies are commonly referred to as the Western Marbled Gecko and the Southern Marbled Gecko. Their placement within the genus may be summarised as follows: *''Christinus'' * * ''Christinus alexanderi'' (endemic to Nullarbor Plain) * * ''Christinus guentheri'', (Lord Howe and Norfolk Island) * * ''Christinus marmoratus'', (widespread: southern mainland, northwest interior) * * *''Christinus marmoratus macrodactylus'' * * *''Christinus marmoratus marmoratus'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Christinus marmoratus」の詳細全文を読む スポンサード リンク
