Information for Rhacodactylus (New Caledonian Geckos)
Rhacodactylus are medium to large geckos of the sub-family Diplodactylinae. 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.
The species are egg layers with the exception of Rhacodactylus trachyrhynchus which gives live birth. Rhacodactylus geckos are sexually dimorphic, with the males possessing larger preanal pores than the females as well as a distinct hemipenis pocket.
With the exception of Rhacodactylus auriculatus, Males tend to be stockier than females. (in R. auriculatus the males are much slimmer than the females.)
