A new species of the genus Gekko Laurenti, 1768 is described from Phu Yen Province, southern Vietnam based on morphological and molecular evidence. Gekko phuyenensis sp. nov. differs from other congeners by its moderate size, with a snout-vent length of 90.292.8 mm; nares in contact with rostral; internasal 1; interorbitals 35 or 36; ventrals 3032; dorsal tubercle rows 9 or 10; precloacal pores 12 or 13 in males and precloacal pits 13 in female; subdigital lamellae under first finger 1821, fourth finger 19 or 20, first toe 1820, and fourth toe 2123; subcaudals median enlarged; no webbing between toes; and the absence of tubercles on hind limbs. Molecular phylogenetic analyses of mitochondrial gene COI (681 bp) using the geckos from Phu Yen and its congeners in southern Vietnam resolve the new species as the sister lineage to G. cf. grossmanni from Khanh Hoa Province. Genetic distances between G. phuyenensis sp. nov. and its congeners in southern Vietnam range from 16.924.2%. The discovery of this new species raises the number of known species of Gekko in Vietnam to 14.
一种新的壁虎属物种，即越南广义壁虎（Gekko phuyenensis sp. nov.），基于形态学和分子证据，在越南广义省被描述。Gekko phuyenensis sp. nov. 与其他近缘种的区别在于其体型中等，吻肛长为 90.292.8 毫米；鼻孔与吻端接触；鼻间鳞 1 枚；眶间鳞 35 或 36 枚；腹鳞 3032 枚；背鳞疣 9 或 10 行；雄性前肛孔 12 或 13 个，雌性前肛窝 13 个；第一指下瓣 1821 个，第四指下瓣 19 或 20 个，第一趾下瓣 1820 个，第四趾下瓣 2123 个；尾下鳞中央大形；趾间无蹼；后肢无疣粒。基于广义省和越南广义壁虎的 COI 基因（681bp）的线粒体基因的分子系统发育分析将新种确定为与庆和省的 G. cf. grossmanni 为姐妹群。G. phuyenensis sp. nov. 与越南广义省的其他近缘种之间的遗传距离为 16.924.2%。这一新种的发现使越南已知的壁虎属物种数量增加到 14 种。
