Based on adult structural features of a single male specimen in Bates' collection of the Muséum national d'Histoire naturelle (MNHN), Paris, a new genus and new species of Orthogoniini (Coleoptera: Caraboidea), Neoorthogonius orientalis Tian and Deuve, from Bombay, Maharashtra State, India is described and illustrated. This new genus is distinct from other genera of the Oriental Orthogoniini by its sub-moniliform antennae, extraordinarily dilated hind femora, narrow pronotum, and abdominal ventrites 4–6 with cilia at hind margins. Neoorthogonius presents a unique lineage. It is more closely allied to Orthogonius Macleay than other genera among Orthogoniini according to the elytral structure and bisetose state of apex of the ligula.
