| Diagnosis | Diagnosis: A species of Calotes morphologically similar to C. mystaceus, with 57 scales around middle of body, ten subralabials and nine infralabials, body compressed, homogeneous scales arranged in regular rows, dorsal and dorsolateral scales larger than ventrals, strongly keeled, pointing backwards and upwards, ventral and gular scales strongly keeled; a small gular pouch is present. In front of the shoulder,. there is a distinct oblique fold of skin covered with small granular black-coloured scales. Nuchal and dorsal crest continuously composed of erect triangular scales, the former lower than the latter. Head shape triangular, forehead feebly concave, its length one and a half times its width. No postorbital spines. Limbs slender, moderately long, fourth toe reaching the hind margin of orbit. Fourth toe longer than third, 18 scales under fourth finger, and 25 under fourth toe. C. mystaceus differs from the new species in having light brown or uncoloured small scales in the fold in front of the shoulder, a broad white or yellow band stretching over the upper lip and extending to the shoulder, falciform spines of nuchal and dorsal crests and much longer nuchal crest spines than in the new species. C. emma with a similar black fold has long postorbital spines. Other species of the genus have body scales pointing backwards (ceylonensis) or backwards and downwards (liolepis, liocephalus) or dorsal scales equal to ventrals with no spines on head (andamanensis), or one row of spines above tympanum (calotes, nigrilabris) or two rows (c. jerdoni). C. nemoricola, C. medogenensis and C. grandisquamis have the fourth toe scarcely longer than third and fewer scales around the body (27 to 43, Smith 1935, and 53-55 in medogenensis, Zhao & Li 1984). C. versicolor, C. maria and C. bhutanensis differ from the new species by lacking a fold in front of the shoulder (Biswas, 1975) [from HALLERMANN 2000]. |
| Comment | Abundance: only known from the type specimen (Meiri et al. 2017). |
| Etymology | Named after its black fold in front of shoulder, plica (lat.) = fold; niger, nigro (lat.) = black, blackish. |
