Sphenomorphus tonkinensis is a recently described new species based on specimens collected from northern Vietnam and Hainan, China. Herein, we report 13 additional specimens of S. tonkinensis from five new localities in Guangxi, Guangdong and Jiangxi, southern China. These specimens were compared with the type specimens of S. tonki- nens&, which allows us to revise the diagnostic characteristics of this newly described species. Additional information on morphological variation, distribution and reproductive biology are provided, which extends our understanding of the natural history of S. tonkinensis. 展开更多

Sphenomorphus incognitus is recorded for the first time outside of China. The new locality record is from the Tay Yen Tu Nature Reserve in Bac Giang Province, northeastern Vietnam at elevations between 200–450 m. Based on the newly collected specimens, we present an expanded description and provide data on the natural history of this species in northern Vietnam. 展开更多

Based on four specimens discovered in the collection of the natural History Museum, London, United kingdom, we present a new distribution record for the skink Sphenomorphus oligolepis for seram island, Maluku Province, Indonesia. This find constitutes the westernmost record for the species and extends its range by over 800 km. the species was heretofore only known from apparently isolated mainland new Guinean populations. 展开更多
