|Diagnosis||Diagnosis: A medium-sized Calotes with a maximum SVL of 97 mm, distinguished from all congeners by the combination of the following characters: 1) head and body robust; 2) body scales relatively small, homogeneous, feebly keeled, arranged in regular rows; 3) upper dorsolateral scales pointing backwards and upwards; 4) 44–50 midbody scale rows; 5) two short and well separated spines, surrounded by three to four scales on either side of the upper head above tympanum; 6) nuchal and dorsal crest continuous, composed of erect compressed scales, directed posteriorly; 7) vertebral spines and scales 35–42 in males and 43–46 in females; 8) oblique fold of skin in front of forelimb insertion dinstict, covered with small granular dark scales; 9) extremities and tail relatively long and slender (see comparison with C. mystaceus for details); 10) bluish to turquoise head and anterior body part, this coloration not well exceeding front limb insertion; 11) yellowish light stripe at upper lip reaching from below anterior corner of eye to posterior end of head; 12) very faint or no dorsal brownish blotches, medially extending across the vertebral crest.|

Coloration (males). The brilliant coloration of adult males is characterized by a brightly colored bluish to tur- quoise head, with bluish coloration continuing posterior- ly to fore limb insertion. There is a relatively faded light (bright yellowish, when under acute distress, a character typical for C. bachae only) stripe at the upper lip crossing the tympanum from beneath the eye to end of head. Gular pouch colored in darker blue, interscale skin black. A tri- angular to crescent-shaped patch of small black scales is present in front of shoulder. Very faint brownish blotch- es extending mid-dorsally over the vertebral crest, from above fore limb insertion on to tail; posterior to fore limb insertion brownish orange in color on trunk and tail; hind limb in a slightly darker brown; venter cream (Wagner et al. 2021).
