A new species of Lygosomine skink (Jarujinia bipedalis sp. nov.) from Suan Pung District, Ratchaburi Province in Central Thailand is described and assigned to a new monotypic genus (Jarujinia). This bipedal skink with only forearms possessing two clawless vestigial fingers appears morphologically to be an evolutionary link between the Lygosomine genera of Larutia and Isopachys, but clearly distinct from both.
