Hebius vibakari is a small species of snake that reaches a maximum total length of 44 cm (17+1⁄4 in), with a tail measuring up to 10 cm (3+7⁄8 in). Dorsally, its body is colored olive or reddish brown and marked with small blackish spots. Some individuals may have a dark olive or blackish stripe running along the vertebral line. The upper labial scales are yellow, with black sutures between them. Each side of the nape of the neck has a diagonal yellow streak with dark edges; these two streaks converge toward the posterior end of the neck. Ventrally, the body is yellow, with a series of brown dots or short lines located at the outer ends of the ventral scales. Its dorsal scales are strongly keeled, with the exception of the outermost row, and are arranged in 19 rows at midbody. It has between 127 and 151 ventral scales, a divided anal plate, and between 59 and 79 divided subcaudal scales. This snake occurs in northeastern China, Japan (on the islands of Honshu, Kyushu, and Shikoku), Korea, and Russia (in Amur Oblast, Khabarovsk Krai, and Primorsky Krai).
