Delma vescolineata, commonly known as the Hunter Valley Delma, is a species of legless gecko from the Pygopodidae family. [1] [2]

Taxonomy

Discovered in 2012, the species is endemic to the Hunter Valley and Liverpool Plains region of New South Wales, Australia, but was believed to be either a separated population of Striped legless lizard (Delma impar), or part of the local population of Leaden Delma (Delma plebeia). DNA analyses in 2022 confirmed its status as a sister species of the Striped legless lizard. The Hunter Valley Delma can be further differentiated from the Striped legless lizard due to its barred lips, weaker stripes and subtle differences in scale and head shape. [3]

Distribution and habitat

Delma vescolineata is the only species of Delma entirely endemic to New South Wales. Like other Delma, the Hunter Valley Delma prefers open grassland habitats, living in burrows, dense grass tussocks, and under rocks. [3]

Pygopodidae, commonly known as snake-lizards, or flap-footed lizards, are a family of legless lizards with reduced or absent limbs, and are a type of gecko. At least 35 species are placed in two subfamilies and eight genera. They have unusually long, slender bodies, giving them a strong resemblance to snakes. Like snakes and most geckos, they have no eyelids, but unlike snakes, they have external ear holes and flat, unforked tongues. They are native to Australia and New Guinea.

Scottsdale Reserve is a 1,328-hectare (3,280-acre) nature reserve on the Murrumbidgee River in south-central New South Wales, Australia. It is 79 kilometres (49 mi) south of Canberra, and 4 kilometres (2.5 mi) north of Bredbo. It is owned and managed by Bush Heritage Australia (BHA), which purchased it in 2006. The purchase was supportive of projects aiming to connect existing fragmented remnant habitat such as K2C. Since the 1870s up until 2006, the land was used for agriculture – primarily sheep grazing with some minor cropping. A significant component of the Reserve has been cleared of native vegetation.

<span class="mw-page-title-main">Excitable delma</span> Species of lizard

The excitable delma is a species of lizard in the Pygopodidae family endemic to Australia. The lizard gets its name from its active and jumpy defense mechanism. It will erratically jump multiple times in succession, each jump pivoting its body in a different direction. D. tincta is a slender, long legless lizard that through evolution lost its limbs. It is found throughout Australia in a variety of habitats, and spends most of its time hiding. Due to its nocturnal nature, it is rare to spot in the wild. This legless lizard is small to moderate in size, with a tail that is three to four times its body length. The typical size of the excitable delma is 250 – 300 mm. This lizard is an insectivore and feeds on insects it finds when travelling through grass, logs, surface soil, and loose rocks. Like all pygopodids, the excitable delma is oviparous and only lays two eggs per clutch.
