Diplodactylinae

Diplodactylinae is a subfamily of geckos within the family Gekkonidae. This group is primarily found in Australasia and the Pacific Islands, with a significant diversity of species across Australia, New Zealand, New Caledonia, and various smaller islands. They are characterized by a wide range of physical adaptations reflecting their diverse habitats, which include rainforests, woodlands, deserts, and rocky outcrops.

Many species within Diplodactylinae are nocturnal, possessing large eyes and specialized toe pads that allow them to climb on various surfaces, including smooth vertical ones. Their diet typically consists of insects and other invertebrates, though some larger species may also consume plant matter or small vertebrates. Reproduction in this subfamily is varied, with most species laying eggs, though some are viviparous, giving birth to live young.

Notable genera within Diplodactylinae include Diplodactylus, often referred to as "prickle-back geckos" or "stone geckos," known for their rough, textured skin. Another prominent genus is Rhacodactylus, which includes the well-known New Caledonian giant geckos such as the crested gecko (Correlophus ciliatus, formerly Rhacodactylus ciliatus) and the New Caledonian giant gecko (Rhineura macracanthus, formerly Rhacodactylus leachianus). The subfamily showcases a remarkable array of evolutionary adaptations, making it a significant group for studying gecko biology and biogeography.
