A new forest skink of the genus Fitzinger, 1843 (Squamata: Scincidae) has recently been described from the high elevation forest of Mount Hon Ba, Khanh Hoa Province, eastern of Langbian Plateau of southern Vietnam. The new member of the genus Sphenomorphus, Yersin’s Forest Skink, S. yersini is described based on morphological characters of four specimens and a fragment of 653 nucleotides of the gene COI. The new species most resembles S. buenluoicus occurring in Kon Tum-Gia Lai Plateau in morphological features but both species can be distinguish from each other by tail length ratio (longer in the new species), ventral scale row (much higher in the new species), and hemipenis shape. This new species is named in honor of the famous physician and bacteriologist, Alexandre Yersin (1863–1943), who discovered the bacterium responsible for bubonic plague. Mount Hon Ba associates with the name of Alexandre Yersin who built a research station on the top of the mountain and worked there.

This is a study participated by Nguyen Thanh Luan, a scientific officer of Asian Turtle Program (ATP) of Indo-Myanmar Conservation (IMC), in cooperation with other Vietnamese colleague from the Institute of Tropical Biology (Ho Chi Minh City) and international researchers from Russian Academy of Sciences (Russia) and Royal Ontario Museum (Canada).
