Rhacodactylus is a genus of medium to large geckos of the family Diplodactylidae. All species in this genus are found on the islands that make up New Caledonia. Genus characteristics include long limbs and toes with well-developed lamellae. Some webbing occurs on the hind limbs and toes. Rhacodactylus possess prehensile tails which also have lamellae to assist in climbing. These are for the most part arboreal geckos. Rhacodactylus are nocturnal geckos. Males tend to be stockier than females with the exception of R. auriculatus in which species the males are much slimmer than the females.
