| Diagnosis | Diagnosis: Bungarus sagittatus sp. nov. is assigned to the genus Bungarus by its recovered phylogenetic position and having enlarged, hexagonal-shaped, midbody vertebrae scales (Smith 1943; Slowinski 1994). This species can be distinguished from other species of Bungarus by the following combination of characters: 15–15–15 dorsal scale rows; 215–217 ventral scales; 48–56 undivided subcaudal; prefrontal suture 2.4–2.6 times length of internasal suture; anterior chin shields larger than posterior chin shields; head of adult uniform black while juvenile black with small dim white patches on temporal and parietal areas; dorsal surface of body black, with 25–31 white narrow bands, white and black bands at midbody covering 1.5–3.0 and 4.5–6.0 vertebral scales, respectively; dorsal black bands of body not intruding ventrals or intruding ventrals less than 0.5 times of width of outer dorsal scales; ventral surface immaculate white; ventral side of tail white with a row of dark brown triangular patches on middle pointing posteriorly; tail relatively long, tail length/total length = 0.140–0.143. (Aksornneam et al. 2024) Additional details (14844 characters) are available for collaborators and contributors. Please contact us for details. |
| Comment | Distribution: The type locality is part of Tenasserim Mountain Range, which lies on Thai-Myanmar borderline, hence the species may occur also in Myanmar. |
| Etymology | Named after sagittata (L.) meaning arrow and in reference to the dark triangular shape on subcaudals which resembles a barbed arrow. |
