A new species of the genus Goniurosaurus, G. zhoui sp. nov., is described based on specimens collected from karst areas in Hainan Island, China. Quantitative comparison of morphological traits and egg size with two known endemic species in Hainan Island and other known congeners confirmed the distinctiveness of G. zhoui sp. nov., which has a moderate size with a snout-vent length of 93.4-97.4 mm; light purple-brown dorsal ground color in adults; a posteriorly protracted nuchal loop on nape; four faint, purple-gray body bands bearing dark purple spots between and on them; eight nasal scales surrounding nares; single internasal; 49-62 eyelid fringe scales; 130-140 scales around midbody; 11 granular scales surrounding the dorsal tubercles; 36-38 precloacal pores in males (absent in females); claws sheathed by four scales, two lateral scales long and curved. We provide the first data on the natural history of the new species and an expanded key to Goniurosaurus species on Hainan Island and the adjacent mainland. The discovery of the new species facilitates our understanding of the speciation process on continental islands.
基于在中国海南岛喀斯特地区采集的标本，描述了睑虎属的一个新物种——周氏睑虎（Goniurosaurus zhoui sp. nov.）。通过对形态特征和卵大小与海南岛另外两个已知特有物种以及其他已知同属物种进行定量比较，证实了周氏睑虎的独特性。周氏睑虎体型适中，吻肛长93.4 - 97.4毫米；成年个体背部底色浅紫褐色；颈部有向后延伸的项圈；身体有四条浅紫色灰色带，带间及带上有深紫色斑点；鼻孔周围有八枚鼻鳞；鼻间鳞单枚；眼睑缘鳞49 - 62枚；中段身体周围有130 - 140枚鳞片；围绕背瘤有11枚粒鳞；雄性有36 - 38枚泄殖腔前孔（雌性无）；爪被四枚鳞片包裹，外侧两枚鳞片长且弯曲。我们提供了关于该新物种自然史的首批数据，并扩充了海南岛及邻近大陆睑虎属物种的检索表。新物种的发现有助于我们理解大陆岛屿上的物种形成过程。
