Calotes is a genus of lizards in the draconineclade of the familyAgamidae. The genus contains 29 species. Some species are known as forest lizards, others as "bloodsuckers" due to their red heads, and yet others (namely C. versicolor) as garden lizards. The genus name Calotes has been derived from the Greek word Καλότης (Kalótës), meaning ‘beauty’, referring to the beautiful pattern of this genus.[2]
Calotes is distinguished from related genera in having uniform-sized dorsal scales, and lacking a fold of skin extending between the cheek and shoulder, and in having proportionately stronger limbs than Pseudocalotes. Compared to Bronchocela, Calotes have a proportionately shorter tail and limbs. Calotes as we know it today was classified by Moody (1980) prior to which all of the above-mentioned genera were included in this genus.
The genus Calotes is still a heterogeneous group that may be divided into the C. versicolor and C. liocephalus groups.[4] The former occurs through most of South Asia and further east. All species in this group have their dorsal and lateral scales directed upward. The latter is restricted to the southern Western Ghats and Sri Lanka. All species in this group have their scales directed back, or up and down, or down only. Whether further splitting is necessary or whether the groups constitute subgenera of a monophyleticCalotes remains to be studied.
