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 es- pecially the high number of bands on the tail and the venter which is heavily speckled in the poste- rior two thirds. Detailed comparisons with other species of the genus Lycodon are provided in the Discussion.
|Comment||Habitat: evergreen karst forest, possibly in caves as the type specimen was found at the entrance of a karst cave.|
|Etymology||This species is named in honour of our friend and colleague Patrick David (MNHN, Paris, France), for his outstanding contributions to the reptile fauna of the Oriental Region.|
