  A new grass lizard, Takydromus toyamai, is described from the Miyako Island Group, Ryukyu Archipelago. The Miyako population has been considered to be conspecific with T. smaragdinus from the Okinawa, Amami, and Tokara Groups of the archipelago, but it is differentiated from populations of these three island groups by having a greater number of ventral rows (eight) and distinctly keeled temporal scales, and in lacking a white ventrolateral line on head and body. The definition of T. smaragdinus is revised accordingly and a lectotype is designated. A dichotomous key is provided for the Japanese and Taiwanese species of the genus Takydromus.
