. A male specimen, in good condition, a longitudinal ventral incision into coelom extending from 64th to 67th ventral. The body preserved in a loose coil, slightly dorsoventrally flattened, with a small constriction slightly below the midbody caused by overly tight tying of a field tag. Both hemipenes removed for further preparation, stored with the specimen. Colours have not noticeably faded in preservative.

Head short, 4.3 mm, and high, 2.6 mm, with steeply domed snout in lateral view. Snout abruptly tapering to blunt, rounded tip in dorsal view. Rounded rostral short in dorsal view, much shorter than the distance between it and prefrontal scales. Nasals undivided, not in contact with each other and each smaller than the rostral that separates them anteriorly. Naris subcircular, situated in the anterior part of the nasal. Paired internasals large, much larger than the nasals and rostral. Prefrontals distinctly larger than the internasals in area and slightly longer along the midline suture (0.7 mm vs. 0.5 mm between internasals). Frontal kite-shaped with the anterior margin slightly convex, noticeably longer (2.6 mm) than broad (1.8 mm) and almost as long as the parietals.

Eyes small with a subcircular pupil. One supraocular and one postocular on each side, subequal in size. One anterior temporal, larger than two subequal posterior temporals. Mental short, broad, with a tripartite anterior end. Anterior two infralabials short and thin, second slightly larger. The length of first two infralabials together shorter than the third, and in lateral view falling notably short of halfway along the length of anterior genials. Fourth and fifth infralabials much larger. Pair of anterior genials, large, meeting substantially along the midline. Posterior pair of genials much smaller, contacting briefly along the midline, largely divided by the intervening anteriormost ventral. First unpaired midventral scale (= first ventral, here) between posterior genials, larger than the subsequent ventrals, longer than wide and the subsequent ventral scales are wider than long. Body subcylindrical, ventral surface slightly flattened, Dorsal scales in 15 rows at the level of fifth ventral until the posteriormost ventral. Dorsal scales macroscopically smooth, regularly arranged, evenly sized across the body and apical pits absent. Ventrals scales 123 in number, all similarly proportioned except for anteriormost ventral. Anal shield undivided, larger than the last ventrals, its posterior margin overlaps six scales on each side, including the subcaudals. Subcaudals in 23 pairs. Tail terminates in bluntly tapering, apical, spine-like scute.</paragraph>
<paragraph pageId="0" pageNumber="219">Scales on the body and tail iridescent. Head scales match this, except for some of the anterior supralabials and infralabials. Overall, the specimen is in shades of brown mottled with off-white and with a distinct off-white collar. Ventral surface paler and less mottled than dorsum, and first three ventrals and adjacent scales mottled off-white continuation of the collar. The main body of each ventral and subcaudal scale are fairly uniform, pale brown, sometimes with an indistinct dark proximal margin anteriorly and off-white margin posteriorly. Upper and sides of the head and body-tail junction are darkest parts of the animal, notably darker than the body. Dorsal head scales generally dark brown with distinct irregular off-white mottling on all scales except for darker frontal. First two supralabials and first three infralabials off-white with a small brown patch only on the second supralabial. Other lateral head scales brownish with very little pale mottling except for a substantial off-white patch on the anterior part of the lower posterior temporal. Collar band off-white, approximately two scales wide with slightly irregular anterior and posterior edges, extends laterally on both sides and connected ventrally where it is two to three scales wide but somewhat broken by brown mottling. Three distinct dark lines on the dorsal surface, running from behind the collar to tail tip, all more than half a dorsal scale wide, being one scale wide at the body-tail junction. Distinct dark dorsal stripe up to almost one scale wide, medially along the middorsal line, narrowly breaking the pale collar mid-dorsally. Middorsal line confined to the midline (eighth) scale row and the pair of dorsolateral lines confined to the 5th dorsal scale row on each side. Three thin, indistinct ventrolateral lines run along the first three dorsal scale rows of each side, becoming feeble and almost invisible at the level of approximately the 30th ventral. Between dark longitudinal lines, scales are various shades of mottled pale brown and off-white. In life, the colouration is almost the same as in the preserved condition except for the pale collar which has faded in ethanol-preserved specimens.</paragraph>

Apical lobes cylindrical and slightly unequal (length and the maximum width of each lobe: 5.3 and 0.9 mm; 4.6 and 0.8 mm, respectively). Hemipenial body unornamented except for a fleshy protuberance on the sulcal side, slightly proximal to the fork, below the sulcus division. The sulcus bifurcates at almost three quarters along the length of the hemipenial body and runs centro-linearly, terminating distally below the apex. In the fully everted hemipenis, the sulcus canal is not exposed but rather enclosed by the lips. The head appears to be rounded and disk-shaped. Towards the distal end, there are 4-8 oblique, inconspicuous flounces on both sides of the sulcus spermaticus. A few scattered microscopic papillae on the flounces at the distal end.

In ZSI-SRC-VRS-287 the upper posterior temporals slightly smaller on both sides; the posterior pair of genials separated by a macroscopically indistinct thin slither of the first ventral; the third ventral is the first scale that is wider than long. ZSI-SRC-VRS-287 is preserved in a U-shaped loose coil and lacks any incision into the coelom; head slightly narrower (not an artefact of preservation); frontal more domed anteriorly, making the prefrontal appear shorter along the midline in dorsal view; midline contact between parietals slightly longer than between both internasals and both prefrontals; third supralabial wider along the lower margin; pale collar less distinct ventrally. In BNHS 3383, the posterior margin of the anal shield overlaps five rather than six scales on each side, including the subcaudals.
