Linnaen Classification Animalia Chordata Reptilia Squamata Sauria Gekkonidae Gekko Type information When an organism is first described by a taxonomist, the physical specimen that is used is known as a holotype. The holotype and the description based on this holotype are important, because they would be used by other taxonomists in the future to identify if what they have discovered is a new species. Type locality: ''Indiis'' in error, ''Java'', Indonesia designated by Mertens (1955) The Tokay Gecko was first described by Carolus Linnaeus in his work, the Systema Naturae, page 205.
