The largest gecko ever to have lived (Nielsen, Bauer, Jackman, Hitchmough & Daugherty 2011). Known from only a single specimen of unknown exact locality. It has been considered a member of the New Zealand endemic genus Hoplodactylus based on external morphological features. However, it has now been established that the species is most closely related to New Caledonian species, and probably originated from New Caledonia (Heinicke, Nielsen, Bauer, Kelly, Geneva, Daza, Keating & Gamble 2023). Distribution: New Caledonia (see remarks).
