|Comment||Diagnosis. A species of the genus Oligodon, characterized by: (1) a large size for the group, up to about 400 mm in total length; (2) deeply forked hemipenes, not spinose but fitted with two large papillae; (3) 17 dorsal scale rows at midbody, 15 before vent; (4) 10–13 maxillary teeth, the last two strongly enlarged; (5) head scalation complete, never including a presubocular (see below); (6) 7 (rarely 8) supralabials; (7) anal plate single; (8) the presence of 10–14 dark brown or black blotches on the upper surface of body + 2–3 on the tail; (9) five major markings on upper head surface: one anterior transverse blotch across the snout; one longitudinal, frontal marking; one pair of paramedian central, oblique streaks, directed posteriorly downwards; and one arrow-shaped nuchal blotch; and (10) branches of the oblique central streak not reaching the ventral scales. Oligodon barroni differs from all other species of the O. taeniatus-group in the combination of (1) 17 scale rows at midbody, (2) the presence of large, dark hexagonal or butterfly-like dorsal blotches on the body and the tail, (3) the absence of a vertebral stripe, and (4) a low number of maxillary teeth. With its dorsal blotches, this species cannot be really confused with any other species of O. taeniatus-group [DAVID et al. 2008].|
