Synonyms | |
Sibynophis collaris, commonly known as the common many-toothed snake, Betty's many toothed snake or the collared black-headed snake, [4] is a species of colubrid snake endemic to South and East Asia.
Rostral scale twice as broad as deep, just visible from above; suture between the internasals shorter than that between the prefrontals; frontal longer than its distance from the end of the snout, as long as the parietals or shorter; loreal as long as or a little longer than deep; one preocular; two postoculars, only the upper in contact with the parietal; temporals 1 (or 2) + 2; 9 or 10 upper labials, fourth, fifth, and sixth entering the eye; 4 lower labials in contact with the anterior chin shields, which are as long as the posterior chin shields. Dorsal scales smooth, without apical pits, in 17 rows. Ventrals 159–190; anal divided; subcaudals divided, 102–131.
Brown above, vertebral region greyish, usually with a series of small round black spots; head with small black spots or vermiculations above, and two black crossbands, one across the posterior part of the frontal and supraoculars, the other across the occiput; a large black nuchal spot or crossband, bordered with yellow posteriorly; a black line from the nostril to the nuchal spot, passing through the eye, bordering the white black-dotted upper lip. Lower parts yellowish, each ventral with an outer black spot or streak, which may be confluent on the posterior part of the body; anterior ventrals with a pair of median dots in addition.
Total length 29 inches (737 mm); tail 9.5 inches (241 mm). [5]
Tehri Garhwal, Uttarakhand, Sub-Himalayan India ( Assam, Simla), Mizoram, Bhutan, Nepal, Myanmar, Thailand, Laos, Vietnam, Cambodia, West Malaysia, China (southeastern Tibet and Yunnan), and Taiwan. Record from Jeju, the southernmost major island of South Korea, refers to Sibynophis chinensis. [1] [3]
