Flower fly species of the genus Monoceromyia Shannon (Diptera: Syrphidae) in India are reviewed and two new species, M. flavoscutata Sankararaman, Anooj and Mengual, sp. nov. and M. nigra Sankararaman, Anooj and Mengual, sp. nov., are described from Tamil Nadu and Arunachal Pradesh (India), respectively. A new synonym is proposed: M. multipunctata (Hull, 1941) is synonymised under M. polistoides (Brunetti, 1923). Moreover, lectotypes are designated for Ceria patricia Brunetti, 1923 and Ceria tredecimpunctata Brunetti, 1923. An identification key to the Indian Monoceromyia species is also provided.
