Type locality: Nam Cave 268 m elevation, near Ban Muang Song, Vang Vieng District, Vientiane Province, Laos
|Types||Holotype: IEBR A.2011.7, male (ventral tail base dissected), (Figs 1–3, 5, 6), collected by Truong Quang Nguyen and Phouthone Kingsada on 6 May 2010.|
|Diagnosis||Diagnosis. A species of the genus Lycodon characterized by: (1) loreal scale not entering orbit; (2) 17 dorsal scale rows at the forepart of the body and 17 dorsal scale rows at midbody; (3) dorsal scale rows keeled; (4) 224 ventrals in the single known male, females unknown; (5) 99 SC in the single known male; (6) a relative tail length of about 0.209 in the single known male (7) 8 supralabials with SL 3–5 touching the orbit; (7) 84 narrow brownish-grey bands on a dark brown body, widening laterally; (8) width of the first band about 1.0 scale on the vertebral row, about 3 ventrals at its base; and (9) the venter heavily dark speckled in the posterior two thirds.|
The new species can be recognized by the combination of the loreal scale not entering orbit, the high number of narrow dorsal bands and especially the high number of bands on the tail and the venter which is heavily speckled in the posterior two thirds. Detailed comparisons with other species of the genus Lycodon are provided in the Discussion.
