A new species of the extinct ant genus Baikuris Dlussky, 1987 (Formicidae: Sphecomyrminae) is described and figured from a male preserved in a piece of w100 Myr amber from Charentes, in southwestern France. Baikuris maximus sp. nov., is distinguished from other species notably by its larger size, its forewing with vein 2MþCu absent and vein 3Cu tubular, and the presence of a subpetiolar process. The diagnosis of the genus is emended, and its distribution during the Cretaceous is briefly discussed.
