We describe a new species of Dendrelaphis from the coastal area in southern Vietnam based on morphological data and nucleotide sequences from one partial mitochondrial gene (Cytb). Dendrelaphis binhi sp. nov. is diagnosed by the following morphological characters: body scale rows 13 at neck and midbody, 9-11 before vent; vertebral scale row feebly enlarged; ventrals 154-158 in males and 161-170 in females; subcaudals 95-106 in males and 95-102 in females; one supralabial touching the eye; 18 or 19 maxillary teeth; hemipenis spinose, reaching 10th or 11th SC, with a slender papilla; cloacal plate divided; dorsum dark brown; and a white stripe along the lower flank. The new species differs from its congeners by an uncorrected p-distance in Cytb sequences of at least 8.1%.
我们基于形态学数据和一个部分线粒体基因（细胞色素b，Cytb）的核苷酸序列，描述了一种来自越南南部沿海地区的新竹叶青蛇属物种。新物种滨海竹叶青蛇（Dendrelaphis binhi sp. nov.）可通过以下形态特征进行鉴别：颈部和身体中部有13行鳞片，泄殖孔前有9至11行；脊椎鳞片行略微增大；雄性腹鳞154至158枚，雌性161至170枚；雄性尾下鳞95至106枚，雌性95至102枚；一枚上唇鳞接触眼睛；上颌齿18或19枚；半阴茎具刺，延伸至第10或11枚尾下鳞，有一个细长的乳突；泄殖板分开；背部深褐色；沿着体侧下部有一条白色条纹。该新物种与其同属其他物种的细胞色素b序列未校正p距离至少为8.1%。
