Calotes andamanensis
''Calotes andamanensis'' is an agamid lizard found on the Nicobar Islands and the Andaman Islands.〔 It is also known as the green crestless forest lizard,〔 Andaman and Nicobar forest lizard, or Andaman green calotes.
The holotype of ''Calotes andamanensis'' is an adult male from Nicobar Islands, India; collected by Frederick Adolph de Roepstorff in 1882.〔〔Zoological Museum collection, Københavns Universitet, Copenhagen, Denmark (ZMUC) 36944〕
==Description==
''Calotes andamanensis'' has been noted as having enlarged keeled scales on caudal surface of thigh, obtusely keeled scales over head, smooth dorsal body scales (uppers six rows directed posterodorsally, remainder posteroventrally). It lacks body crest, antehumeral pit present. ''Calotes andamanensis'' has 67 scales around its midbody. Its third toe is shorter than its fourth toe. This species is distinguished from ''Calotes aurantolabium'' in having smooth dorsals, dorsal body scales unequal, upper six scale rows larger, remainder equal in size to ventral scales; three enlarged scales on caudal thigh; dorsal head scales obtusely keeled; parietal ridge raised; enlarged scale between nuchal crest and tympanum; antehumeral pit present; toe-IV longer than III; stretched hindlimb reaches eye. Distinguished from ''Calotes versicolor'' and ''Calotes liocephalus'' groups and ''C. rouxi'' and ''C. ellioti'' in presence of enlarged keeled scales on caudal surface of thigh. Distinguished from ''Calotes versicolor'' group lizards in scale orientation – distinguished from ''Calotes versicolor'' in having an antehumeral pit; distinguished from ''C. nemoricola'' and ''C. grandisquamis'' in having equal size dorsal and ventral scales, toe-IV longer than III, scales around midbody 67 (36-43 and 27-35 respectively); distinguished from ''C. calotes'' in lacking flattened spines above tympanum. Distinguished from ''C. ellioti'' and ''C. rouxi'' in having an antehumeral pit and in lacking spines. It is distinguished from the species ''Calotes liocephalus'' and similar lizards (''C. ceylonensis, C. desilvai, C. liolepis, C. nigrilabris'') in lacking spines on the head. It is distinguished from ''C. liocephalus'' by midbody scale count and body crest.〔
It originally included the species now described as a distinct species, ''Calotes aurantolabium''. The description given here is used in the newer sense, rather than the one of by Ishwar and Das.〔Ishwar, N.M. & Das, I. 1998 Rediscovery of ''Calotes andamanensis'' Boulenger 1891, and a reassessment of the type locality.
