TypesHolotype: NRM (NHRM) 3095, adult, sex not determined. Collected by B. Björkegren, July 1938-April 1939. 
DiagnosisDiagnosis: A species of the genus Lycodon, characterized by: (1) loreal not entering orbit; (2) 19 dorsal scale rows on the forepart of the body and 17 or 19 rows at midbody; (3) upper dorsal scale row or two upper rows plus vertebral row distinctly keeled; (4) 14-25 bands on body; (5) first band starting at Ven 10-15; (6) upper maxillary teeth: 6 + 3-4 + 2. This species can mostly be recognized by the higher number of dorsal rows on the first third of the body, namely 19 vs 17 in other species treated here, and by the lower number of dorsal bands.

CommentThe description of this species was first published in SMITH’s book who ascribed it to RENDAHL, who in turn had described it in a letter to SMITH.

In Ziegler et al. (2004: 34), ZFMK numbers of Lycodon cf. paucifasciatus and Dinodon cf. rufozonatum were interchanged. In addition, in that same publication, fig. 44 depicts Lycodon paucifasciatus, but it was interchanged in the pdf file of that paper with fig. 43.

Behavior: nocturnal. 
EtymologyThis specific name is based on the Latin adjectives paucus, meaning “few” or “little”, and “fasciatus”, banded, due to the low number of dorsal bands of the holotype.
