CommentDiagnosis. A species of the genus Lycodon characterized by: (1) a loreal scale entering the orbit; (2) 17 dorsal scale rows anteriorly and at midbody; (3) upper and vertebral dorsal rows (6–12) are keeled; (4) 210–216 ventrals in males, and 215 ventrals in the single female known; (5) 95–96 subcaudals in males, and 92 subcaudals in the single female; (6) relative tail length ca. 0.231–0.232 in males, and 0.215 in the female; (7) 8 supralabials with SL 4– 6 touching the orbit; (7) 32–40 pale bands on a dark body; (8) breadth of the anteriormost band 1 dorsal scale middorsally, 3–4 ventrals, midventrally; (9) belly with discreet bands throughout, and (10) dark ventrals on the throat.

This species can be recognized by its long tail (tail length/total length 0.231–0.232 in males, 0.215 in females, vs. 0.198–0.225 in males, 0.193–0.219 in females of L. fasciatus), and the high number of subcaudals (95–96 in males, and 92 in females). Also, its anteriormost pale band is very narrow, being 1 dorsal scale broad middorsally in all 4 known specimens, vs. 1–5 dorsals (x = 2.5 in 62 specimens) in the L. fasciatus group, with the anteriormost band starting at ventral 4–7 (vs. usually ventral 10-16 in L. fasciatus and in species of the L. ruhstrati group). Fur- thermore, the new species has a dark throat, whereas in L. fasciatus usually the throat is white (except in some individuals from parts of Yunnan; Vogel et al. unpublished data). More detailed comparisons with other species of the genus Lycodon are provided by VOGEL & LUO 2011.
