|Diagnosis||Diagnosis and comparison. A medium sized Monilesaurus with a maximum SVL of 83.4 mm, arboreal species characterized by the backward and downward orientation of lateral body scales; presence of antehumeral fold, throat fold not prominent as the antehumeral fold; 46–52 midbody scale rows; nuchal crest composed of 3–6 small spines; two small separated supratympanic spines; a very small tubercle like postorbital spine barely distinguishable from the surrounding head scales; dorsal and lateral scales feebly keeled, stronger towards ventrals, ventral scales strongly keeled; scales on ventral thigh region feebly keeled; paired postmentals, first pair separated by a single scale; 21–24 subdigital lamellae under fourth finger, 25–30 subdigital lamellae under fourth toe; 9–10 supralabials and 8–9 infralabials; greenish brown above with darker dorsum, a white band below the eye extending till end of jaw.|
Monilesaurus montanus gen. et sp. nov. can be distinguished from its sister species based on the combination of following characters: larger body size: adult SVL 61–83.4 mm, n=8 (vs. M. ellioti comb. nov. adult SVL 59.4– 73.8 mm, n=9; M. rouxii comb. nov. adult SVL 51.4–74.8 mm, n=9); lower number of midbody scale rows 46–52 (vs. 62–64 in Monilesaurus acanthocephalus gen. et sp. nov., 52–58 in M. ellioti comb. nov., 52–56 in M. rouxii comb. nov.), presence of a very small, indistinct tubercle like, isolated spine in the posterior corner of orbit (vs. absent in M. rouxii comb. nov., long, distinct isolated spine in M. ellioti comb. nov. and M. acanthocephalus gen. et sp. nov.), 3–6 small nuchal spines (vs. 7–8 small nuchal spines in M. rouxii comb. nov., 6 much longer nuchal spines in C. acanthocephalus gen. et sp. nov., 3–4 long nuchal spines in M. ellioti comb. nov.); small isolated spine on the back of head and above tympanum (vs. longer, prominent spines in M. ellioti comb. nov. and M. acanthocephalus gen. et sp. nov.) presence of white band below the eye (vs. none in M. rouxii comb. nov.; in the form of a spot in M. ellioti comb. nov. and M. acanthocephalus gen. et sp. nov.).
|Comment||Behavior: diurnal |
Habitat: semi-arboreal to arboreal in habit and so far, has been recorded from montane shola forests. Individuals were mostly found at night, sleeping on branches of stunted trees within sholas or actively moving on tree trunks.
|Etymology||The species epithet is derived from the word ‘montane’ referring to the restricted distribution of this species to high elevation forests (> 1500 m a.s.l).|
