Diagnosis | Diagnosis: A species of the genus Trimeresurus which is assigned to the subgenus Trimeresurus based on the following morphological attributes: a long papillose or calyculate hemipenis and partially fused first supralabial and nasal scales (Malhotra and Thorpe 2004a; David et al. 2011). The new species Trimeresurus ciliaris sp. nov. can be distinguished from all other congeneric species by the following combination of morphological characters: three or four small convex supraocular scales; internasals not in contact; small scale between nasal and the scale formed by the fused second supralabial and loreal present; dorsal scales in 17–17–15 rows; ventral scales 172–175 in males, 171 in a single female; subcaudal scales 59–63 in males, 52 in a single female, all paired; in life an emerald-green dorsum with reddish-brown crossbands; creamy-white venter lacking dark dots or stripes on the lateral sides of the ventrals; iris olive-green with faded-brown horizontal stripe; tail dark brown mottled with rusty spots; white vertebral spots present in both sexes located approximately every two or three dorsal scales; dark brown spots forming discontinuous pattern present on 1–3 lateral dorsal scale rows; males having a reddish-brown postocular stripe. (IDIIATULLINA et al. 2023) Additional details (11479 characters) are available for collaborators and contributors. Please contact us for details. |

Etymology | The species name “ciliaris” is a Latin adjective in the nominative singular, masculine gender, derived from Latin word “cilium” meaning “an eyelash”, and is given in reference to the characteristic small and distinct supraocular scales in the new species, which resemble eyelashes or eyebrows in lateral view. |
