Chengodumala Dwarf Gecko

Disclaimer: Copyright infringement not intended.

Context

Scientists have discovered a new species of ground-dwelling gecko, a species of lizard, from the coastal forests of northern Kerala.

About the species

The beautifully-patterned Cyrtodactylus (Geckoella) chengodumalaensis is a small, nocturnal species that is found on the ground among leaf litter and rocks in forests and partially human altered landscapes like orchards and other areas with canopy cover.
The Chengodumala or Coastal Kerala Geckoella is endemic to low hills and coastal forest in northern Kerala.
The second new species of gecko to have been described from Chengodumala highlights the fact that biodiversity of these low-elevation hillocks is understudied, with many more species remaining to be discovered.

Chengodumala is a midland hillock in Kozhikode district, and also the type locality for Cnemaspis chengodumalaensis (Chengodumala dwarf gecko).

Cyrtodactylus

It is a diverse genus of Asian geckos, commonly known as bent-toed geckos, bow-fingered geckos, and forest geckos.
The genus has about 300 described species as of 2020, which makes it the largest of all gecko genera.
As of 2023, Cyrtodactylus santana is the last known species in its family.

Description

Instead of possessing dilated digits like other geckos, members of Cyrtodactylus have slender, curved toes to which the common names for the genus can be attributed.
