Sitana is a genus of lizards, collectively known as the fan-throated lizards, from the family Agamidae. They are found in Nepal, India, Sri Lanka and Pakistan. [1] The genus comprises fourteen species, including several recently discovered species, [2] such as two new species from Sri Lanka. [3] In 2016, a new genus named Sarada was erected, consisting of one former Sitana species and two newly described ones. Sarada is the sister genus of Sitana. Together they form a clade which sister group is Otocryptis . [1]

Description

Sitana are small to medium-sized lizards. They are ground dwellers, primarily eating insects but also mollusks and plant seeds. [1]

Males measure 37–47 mm (1.5–1.9 in) and females 36–52 mm (1.4–2.0 in) in snout–vent length. In an example of convergent evolution, males have prominent dewlaps, similar to anoles, which are used in communication during the breeding season. The dewlap may be small to large, depending on the species. Females lack the dewlap. [1]

<span class="mw-page-title-main">Dactyloidae</span> Family of reptiles

Dactyloidae are a family of lizards commonly known as anoles and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloinae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with Polychrus, but the latter genus is not closely related to the true anoles.

<i>Otocryptis</i> Genus of lizards

Otocryptis is a genus of agamid lizards from the Indian subcontinent. It is the sister group for the clade formed by Sitana and Sarada. The divergence is estimated to have occurred about 12 million years ago.

<span class="mw-page-title-main">Dewlap</span> Skin hanging below the jaw of animals

A dewlap is a longitudinal flap of skin or similar flesh that hangs beneath the lower jaw or neck of many vertebrates. More loosely, it can be various similar structures in the neck area, such as those caused by a double chin or the submandibular vocal sac of a frog. More generally, it can be any hanging mass of skin, such as a fold of loose skin on an elderly person's neck, or the wattle of a bird. Dewlaps can be considered as a caruncle, defined as "a small, fleshy excrescence that is a normal part of an animal's anatomy".
