| Diagnosis | DIAGNOSIS. Lycodon zawi differs from other Lycodon of the Asian mainland by the following combination of character states: 17 dorsal scale rows at mid-body, preocular scale present (Fig. 1), loreal scale not in contact with internasal (Fig. |), anal scale divided, poorly-developed white crossbands on a brownish black dorsum, and without a well-developed nape band (Fig. 1). In terms of scale characteristics, L. zawi is similar to L. laoensis (Figs. 2-4), known from Northeast India, China, Malaysia, Thailand, Laos, Vietnam, and Cambodia (Lanza 1999), but differs by its brownish black and white dorsal coloration (brownish black and yellow in L. laoensis), the poorly-developed light crossbands (well-developed in L. /aoensis), and the lack of a nape band. Lycodon zawi differs from other Myanmar and Northeast India congeners as follows: from L. aulicus/capucinus (Figs. 2—4) in lacking a nape band, in lacking a sharply defined white lip margin, and in having a loreal scale that does not contact the internasal scale; from L. kundui in lacking a nape band, having 17 mid-body scale rows (15 in L. kundui), and in having 8 or 9 supralabials (7 in L. kundui); from L. fasciatus (Figs. 2-4) in lacking loreal contact with the eye, in lacking well-developed light crossbands, and in having smooth dorsal scales; from L. jara (Figs. 2—3) in having light bands and in having a loreal scale that does not contact the internasal scale. Lycodon zawi resembles L. travancoricus (Western Ghats and southern Pakistan) and L. tiwarii (Andaman and Nicobar Islands; Biswas and Sanyal 1965) in scalation. From L. travancoricus, L. zawi differs by its divided anal and weakly developed light bands (L. travancoricus has well-developed yellow bands which bifurcate on the sides). Lycodon zawi differs from L. tiwarii in having white bands on a dark dorsum (white reticulations on a dark dorsum in L. tiwarii).
