A new species of the genus Hebius Thompson, 1913 is described from Youjiang District, Baise City, Guangxi Zhuang Autonomous Region, China, based on a single adult female specimen. It can be distinguished from its congeners by the following combination of characters: (1) dorsal scale rows 19-17-17, feebly keeled except the outermost row; (2) tail length comparatively long, TAL/TL ratio 0.30 in females; (3) ventrals 160 (+ 3 preventrals); (4) subcaudals 112; (5) supralabials 9, the fourth to sixth in contact with the eye; (6) infralabials 10, the first 5 touching the first pair of chin shields; (7) preocular 1; (8) postoculars 2; (9) temporals 4, arranged in three rows (1+1+2); (10) maxillary teeth 30, the last 3 enlarged, without diastem; (11) postocular streak presence; (12) background color of dorsal brownish black, a conspicuous, uniform, continuous beige stripe extending from behind the eye to the end of the tail; (13) anterior venter creamish-yellow, gradually fades to the rear, with irregular black blotches in the middle and outer quarter of ventrals, the posterior part almost completely black. The discovery of the new species increases the number of species in the genus Hebius to 51.
一种新的 Hebius 属物种，根据来自广西壮族自治区百色市右江区的单一成年雌性标本描述。它可以通过以下特征组合与同属种区分开来：（1）背鳞行 19-17-17，除最外层行外，弱棱；（2）尾巴相对较长，雌性 TAL/TL 比值为 0.30；（3）腹鳞 160（+3 枚前腹鳞）；（4）尾下鳞 112；（5）上唇鳞 9，第四至第六枚与眼接触；（6）下唇鳞 10，前 5 枚与第一对颏鳞接触；（7）前鼻鳞 1；（8）后鼻鳞 2；（9）颞鳞 4，排成三行（1+1+2）；（10）上颔齿 30，最后 3 枚增大，无间隙；（11）后眼斑存在；（12）背部棕色黑色，有明显的、均匀的、连续的米色条纹从眼后延伸到尾巴末端；（13）前腹淡黄色，逐渐向后褪色，在腹鳞的中外部四分之一有不规则的黑色斑点，后部几乎完全黑色。新种的发现使 Hebius 属的物种数量增加到 51 种。
