The harlequin gecko (Tukutuku rakiurae), [4] formerly Hoplodactylus rakiurae, [5] is a species of gecko, a lizard in the family Diplodactylidae. The species is endemic to Stewart Island/Rakiura in the far south of New Zealand, where it was discovered in 1969. [6] In terms of distribution it is one of the southernmost gecko species in the world. [7]

Contents

Etymology

The generic name, Tukutuku, refers to the Māori ornamental lattice work called Tukutuku, which the dorsal pattern of this species resembles. [3] The specific name, rakiurae, refers to Rakiura, the Maori name for Stewart Island. [3]

Habitat

The preferred habitats of T. rakiurae are shrubland and wetlands. [1]

Reproduction

T. rakiurae is viviparous. [3]

Conservation status and threats

The harlequin gecko has been assessed as Endangered by the IUCN since 2018, owing to its rarity, small range and declining population. Stewart Island is overrun with invasive predators such as cats ( Felis domesticus ) and rats ( Rattus rattus, R. exulans , and R. norvegicus ), which have also contributed to declines among native bird species. Like other New Zealand geckos, harlequin geckos breed and develop very slowly, with a female giving birth to only one offspring every two or three years. Each generation, which takes about 20 years to mature, appears to have about 30% fewer individuals than the previous generation. Poaching for the international pet trade is another potential threat: although the species has yet to be introduced into the pet trade, it is a known target of poachers acting within Rakiura National Park. [1]

As of 2012 the Department of Conservation (DOC) classified the harlequin gecko as Nationally Vulnerable under the New Zealand Threat Classification System. [8] The species is protected under Appendix III of the Convention on International Trade in Endangered Species (CITES), meaning international import/export is regulated by the CITES permitting system.

<i>Hoplodactylus</i> Genus of lizards

Hoplodactylus is a genus of geckos in the family Diplodactylidae. The genus is endemic to New Zealand, one of the seven genera of geckos found only in New Zealand. Hoplodactylus comprises two species of large to gigantic brownish lizards.

<i>Naultinus</i> Genus of lizards

Naultinus is a genus of geckos that are endemic to New Zealand. On account of their striking colouration, species in the genus Naultinus are commonly known as green geckos. There are nine described species in the genus. Species in the genus share a number of traits that set them apart as quite different from the rest of the world's two thousand odd gecko species, which are generally brown in colour, ovivaparous, short-lived and nocturnal. In contrast, Naultinus are green, ovovivaparous, live up to 30 years or more and are strictly diurnal. New Zealand has a temperate, maritime climate, and in terms of distribution Naultinus is one of the southernmost gecko genera in the world — some species live in habitats in the South Island which receive regular snowfall in winter. Animals in this genus possess several physiological and behavioural adaptations to cope with these periods of low temperatures and adverse weather.

<i>Gigarcanum</i> Extinct species of lizard

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 of at least 60 cm (23.6 in). 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. While originally suggested to have been from New Zealand and the kawekaweau of Māori oral tradition, DNA evidence from the specimen suggests that it originates from New Caledonia.

<span class="mw-page-title-main">Pygopodoidea</span> Superfamily of lizards

Pygopodoidea is a gecko superfamily and the only taxon in the gekkotan subclade Pygopodomorpha. The clade includes three Australasian families: Diplodactylidae, Carphodactylidae, and Pygopodidae. Traditional gekkotan systematics had considered Diplodactylidae and Carphodactylidae as subfamilies of the family Gekkonidae, but recent molecular work have placed Pygopodidae within Gekkonidae making it paraphyletic. These analyses have shown support of Pygopodidae and Carphodactylidae being sister taxa, with Diplodactylidae occupying a basal position in Pygopodoidea.

The Aupōuri green gecko, also known as the North Cape green gecko or yellow-lipped green gecko, is a species of gecko in the family Diplodactylidae. While the existence of the species was known for many years, it was undescribed until early 2021, with its scientific name being Naultinus 'North Cape' prior to description as N. flavirictus.
