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.
