摘要
A new gobiiform fish Odontobutis hayashitokuei sp. nov. is decribed from middle Miocene freshwater deposits of the Chojabaru Formation in Iki Island, Nagasaki, Japan based on a single specimen. This new species differs from other species of the genus Odontobutis in having 21 caudal vertebrae and a smaller head. Odontobutis hayashitokuei sp. nov. is most similar to O. obscura in having almost the same position of dorsal and anal fins. This is the first fossil species of the genus Odontobutis and suggests that the origin of the genus extends to the middle Miocene, about 15 Ma.
