Oedura cincta, or inland marbled velvet gecko, is an Australian species of gecko.

Contents

Description

The inland marbled velvet gecko measures with a snout-vent length an average of 90mm but up to 108mm, with a thick tail and five or six light bands across the body over a purplish brown background. These bands are especially evident in juveniles. Light yellow flecking appears as they mature into adults, making the banding less distinct. [1] The tail may become thinner in times of stress and lowered body condition. [2] The base colour of purple brown appears in adults during the day, with a more dull grey appearance at night. [1] They can be distinguished from the morphologically similar O. marmorata by a longer body length and a longer and slimmer tail which is never thicker than the head. [1]

Etymology

Cinctus is the Latin singular masculine form of cingo, which means to go around, surround or encompass. This is likely in relation to the bands present on the tail of the Oedura cincta. [3] Oedura means swollen tail, in reference to the significantly enlarged tail common to most Oedura spp.. [4]

Taxonomy and evolution

Divergence of Oedura cincta from other species occurred in the plio-pleistocene for isolated populations, and early pliocene for central populations. [2] The species was recently brought out of synonymy by Oliver and Doughty (2016) from Oedura marmorata , a close relative, from which four distinct species have now been detailed; O. cincta, O. fimbria, O. bella and the originally described O. marmorata . [1] As saxicoline (rock-dwelling) lizards, singular species such as O. cinta can encompass multiple distinct lineages as their habitats differ and can be considered two evolutionary significant units (ESUs). [1] In the case of O. cincta, this species encompasses both the eastern and central lineages. [1] O. derelicta is considered a synonym of O.cincta in junior form. [1]

Distribution and habitat

Oedura cincta have been found to have a wide distribution in central Australia and inland eastern Australia. [2] Oedura cincta are tree and rock dwelling geckos found to inhabit mostly granite, quartz, sandstone and limestone rocks as well as trees. [2] The eastern ESU (evolutionary significant units) have been found to inhabit western New South Wales and Queensland woodland areas throughout the Cooper and Darling basins, residing mostly in tree hollows and bark of small trees, predominantly Casuarina spp.. [1] They are also known to inhabit rocks when available and have been found in this habitat in the Flinders Ranges. [1] Proportionately more arboreal (tree-dwelling) O. cincta are found throughout inland eastern Australia (eastern ESU) while the rock dwelling lineages are less widely distributed and found mostly in central Australia (central ESU). [2] Two isolated populations of the central ESU have been identified in the South of the Northern Territory in the Macdonell and Reynolds Ranges foraging, and these have been predominantly rock-dwelling. [1]

Reproduction

Oedura cincta are oviparous, meaning they lay eggs rather than give birth to live young, and are thought to have a clutch size that averages two young. [4]

Diet

Oedura spp. forage for arthropods over vertical surfaces such as rocks and trees as well as on the ground. [5] Oedura spp. have also been seen lapping sap from trees, usually wattles. [5]

The Carphodactylidae, informally known as the southern padless geckos, are a family of geckos, lizards in the infraorder Gekkota. The family consists of 32 described species in 7 genera, all of which are endemic to Australia. They belong to the superfamily Pygopodoidea, an ancient group of east Gondwanan geckos now only found in Australasia. Despite their well-developed limbs, molecular phylogenies have demonstrated that Carphodactylidae is the sister group to Pygopodidae, a highly specialized family of legless lizards.

The Diplodactylidae are a family in the suborder Gekkota (geckos), with over 150 species in 25 genera. These geckos occur in Australia, New Zealand, and New Caledonia. Diplodactylids are the most ecologically diverse and widespread family of geckos in both Australia and New Caledonia, and are the only family of geckos found in New Zealand. Three diplodactylid genera have recently been split into multiple new genera.

S.williamsi has been grouped within a clade of seven other species that are believed to have diverged from their ancestors around 16 million years ago S.williamsi can be distinguished from closer relatives by arboreality and diurnal (day-active) activity.

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.
