A new rock-dwelling gecko species, now called “Cnemaspis rammalensis”, was discovered in Sri Lanka as late as 2014. This largest Gecco species of the genus Cnemaspis in Sri Lanka was found in the unique rocky habitat of caves and crevices in the Rammalakanda Forest in Hambantota District. The English, Sinhala and Tamil names of this newly discovered species are “Rammale Day Gecko”, “'Rammale Diva Huna” and “Rammale Pahalpalli” respectively. "Cnemaspis" is a genus of diurnal geckos.
With about 75 species found in Asia, Cnemaspis is one of the most diverse genera of geckos or even lizards. In Sri Lanka, it is the only genus which contains purely diurnal geckos, this is why they are commonly called “Day geckos”.
Other genera of geckos recorded in Sri Lanka are Calodactylodes, Geckoella, Hemidactylus, Hemiphyllodactylus, Lepidodactylus, Gehyra. According to research in 1877 there were sixteen species of geckos mentioned in the book “Reptile Fauna of Ceylon”. The total number now has risen to 42 now. There are about 1,500 different Gecko species worldwide.
Geckos are considered to be the most primitive living saurian in Sri Lanka. They are the most species-rich group of lizards Geckos are found in warm climates throughout the world, not at all avoiding human habitats. Geckos are unique among lizards in their vocalizations, using Geckos are named after their chirping sounds they utter in social interactions with conspecifics. Another characteristic is, that most geckos cannot blink, instead of this they often lick their eyes to keep them clean and moist. Most gecko species can lose their tails in defense.
