We describe a new species of the genus Hemiphyllodactylus on the basis of four specimens from Bidoup - Nui Ba National Park, Da Lat Plateau, Lam Dong Province, Vietnam. The new species, Hemiphyllodactylus dalatensis sp. nov., is distinguished from the remaining congeners by a combination of the following characters: a bisexual taxon; maximum SVL of 45.9 mm; dorsal scale rows 16; ventral scale rows 8 or 9; chin scales 710; postmental scales enlarged; femoral and precloacal pores in a continuous series, 2325 in total in males, absent in the female; digital lamellae formula 4-5-5/6-5 (forefoot) and 5-6-6-6/5 (hind foot); cloacal spurs 2 or 3 on each side in both males and female; subcaudal scales not enlarged; dorsal trunk pattern with two paravertebral stripes, formed by two rows of dark spots; dark lateral head stripe distinct; postsacral mark cream or orange and bearing anteriorly projecting arms. In phylogenetic analyses, the new species is recovered as the sister taxon to a clade including all species from India although support values are low from all analyses.
我们基于来自越南林同省大叻高原的比多乌-努伊巴国家公园的四个标本描述了一个新的半叶趾虎属物种。新种，大叻半叶趾虎（Hemiphyllodactylus dalatensis sp. nov.），通过以下特征的组合与其他近缘种区分开来：两性种；最大 SVL 为 45.9 毫米；背鳞行 16 行；腹鳞行 8 或 9 行；颏鳞 710 枚；后颏鳞增大；股孔和前肛孔呈连续系列，雄性总计 2325 个，雌性缺失；指趾下瓣式为 4-5-5/6-5（前足）和 5-6-6-6/5（后足）；雄性和雌性每侧的泄殖腔刺均为 2 或 3 个；尾下鳞无增大；背部躯干图案有两条背侧条纹，由两排暗点组成；暗侧头纹明显；肛后斑为奶油色或橙色，并有向前突出的臂。在系统发育分析中，尽管所有分析的支持值都很低，但该新种被恢复为一个包括来自印度的所有物种的分支的姊妹分类群。
