The gargoyle gecko, knob-headed giant gecko, New Caledonia bumpy gecko, or New Caledonian bumpy gecko (Rhacodactylus auriculatus) is a species of gecko found only on the southern end of the island of New Caledonia. Its habitat is threatened by deforestation on the island. This species of gecko is the smallest of the six recognized species in its genus where they often reach about 125 mm in size. This gecko, along with several other Rhacodactylus species are being considered for protective measures by CITES, which would put restrictions on their exportation. This gecko was first described by Bavay in 1869.
