Gigarcanum delcourti, formerly Hoplodactylus delcourti, is an extinct species of gecko in the family Diplodactylidae. It is the largest known of all geckos, with a snout-to-vent length (SVL) of 37 cm (14.6 in) and an overall length (including tail) of at least 60 cm (23.6 in).[2] It is only known from a single taxidermied specimen collected in the 19th century that was rediscovered unlabelled in a museum in France. The origin of the specimen was undocumented.[1] While originally suggested to have been from New Zealand and the kawekaweau of Māori oral tradition,[3][4][5] DNA evidence from the specimen suggests that it originates from New Caledonia.[6]
