Synonyms

Calodactylodes is a genus of lizards, commonly called golden geckos, in the family Gekkonidae (geckos). The genus is distributed in peninsular India and Sri Lanka. Lizards in the genus Calodactylodes are primarily distinguished from other lizards by their characteristic, paired flower petal-like skin extensions on their fingers and toes.

Taxonomy

The generic name, Calodactylodes, created in 1928 by Embrik Strand, is a replacement name for Beddome's Calodactylus. Replacement was necessary because when Richard Henry Beddome created Calodactylus in 1870, this name was already preoccupied by a genus of beetles which Émile Blanchard had named Calodactylus in 1850.

Species

The following two species are recognized as being valid. [2]

Geographic range

The Indian species, C. aureus, is found in the Eastern Ghats hill range in Odisha, Andhra Pradesh, and Tamil Nadu states. The Sri Lankan species, C. illingworthorum, is found in the Eastern Province, Sri Lanka.

Natural history

Both species of Calodactylodes live in rock crevices, are nocturnal, insectivorous, and very social, living in colonies of multiple individuals. During breeding seasons, the dominant male acquires a brilliant golden yellow colour all over the body, and hence the common name. Females and young ones are drab brown, camouflaging among the rocks. These geckos are very vocal, and their loud rattling calls are often to be heard inside the dark ravines. They reproduce by laying eggs. Females are communal nesters and many may lay their eggs (often numbering in thousands) together simultaneously in a safe and suitable rock crevice, away from predators' reach.

Eastern Ghats

The Eastern Ghats are a discontinuous range of mountains along India's eastern coast. The Eastern Ghats run from the northern Odisha through Andhra Pradesh to Tamil Nadu in the south passing some parts of Karnataka as well as Telangana. They are eroded and cut through by four major rivers of peninsular India, viz. Godavari, Mahanadi, Krishna, and Kaveri. The cradle of Eastern Ghats is Villupuram district in Tamil Nadu.

Colonel Richard Henry Beddome was a British military officer and naturalist in India, who became chief conservator of the Madras Forest Department. In the mid-19th century, he extensively surveyed several remote and then-unexplored hill ranges in Sri Lanka and south India, including those in the Eastern Ghats such as Yelandur, Kollegal, Shevaroy Hills, Yelagiri, Nallamala Hills, Visakhapatnam hills, and the Western Ghats such as Nilgiri hills, Anaimalai hills, Agasthyamalai Hills and Kudremukh. He described many species of plants, amphibians, and reptiles from southern India and Sri Lanka, and several species from this region described by others bear his name.

Forest spotted gecko

The forest spotted gecko or Erode ground gecko is a species of gecko that is endemic to hills of South India, in parts of Eastern Ghats and Western Ghats. It was first described from hills near Erode in Tamil Nadu in 1870. Subsequently, this species was thought to be similar to Cyrtodactylus collegalensis, but recent studies have confirmed that they are distinct. This species has been sighted in hills around Coimbatore, Tirupur and Erode, in parts of the Eastern Ghats in Tamil Nadu.

<i>Kaestlea</i>

Kaestlea is a genus of skinks. These skinks are small, shiny, smooth-scaled species. They are diurnal, terrestrial and insectivorous. They lay eggs to reproduce. These skinks are identified by their distinct blue tail colour. They live in tropical rainforest and montane forest habitats. These secretive skinks silently move through thick leaf-litter on forest floor. They are all endemic to the Western Ghats mountains and in some parts of Eastern Ghats (Shevaroys) of South India.
