The kawekaweau (Hoplodactylus delcourti), also commonly known as Delcourt's sticky-toed gecko[3] or Delcourt's giant gecko, is an extinct species of lizard which is one of the largest known of all geckos with a snout-to-vent length of 370 mm (14.6 in) and an overall length of at least 600 mm (23.6 in),[4] surpassed only in size by the 40 centimetres (16 in) Rodriguez Island night gecko, Phelsuma gigas.[5] The Kawekaweau was endemic to New Zealand, and is now believed to be extinct.[1][a]

History[edit]

According to his own report, in 1870, a Māori chief killed a kawekaweau he found under the bark of a dead rata tree in the forests of the Waimana Valley[8] (now protected as part of the northern section of Te Urewera National Park[9]). This is the only documented report of anyone ever seeing one of these animals alive.[8] He described it as being "brownish with reddish stripes and as thick as a man's wrist." Whether his story was true or not is unknown. A single stuffed museum specimen was "discovered" in the basement of the Natural History Museum of Marseille in 1986;[7] however, the origins and date of collection of the specimen remain a mystery, as when it was found, it was not labelled.[8] Scientists examining it eventually concluded it was from New Zealand and was in fact the lost "kawekaweau", a giant and mysterious forest lizard of Maori oral tradition.

Etymology[edit]

This animal's specific epithet is taken from the surname of French museum worker Alain Delcourt, who discovered the forgotten specimen in the basement of the Natural History Museum of Marseille.[3][7]

Notes[edit]

  1. ^ The largest extant species of gecko is Leach's giant gecko of New Caledonia, at 360 mm (14.2 in) long;[6] the Duvaucel's gecko is the largest surviving species of gecko in New Zealand, also one of the largest in the world.[7]
