Abstract
Here we describe the flat wasp genus Glutodon gen. nov., and its single species G. mikeaensis sp. nov. from Madagascar. The males of this genus are easily recognized among the other genera of Pristocerinae by having the metasoma with a conical flap expansion on the sternum VIII and the hypopygium with the anterolateral apodeme very thick along its length with a very gibbous tip, both conditions unique in Bethylidae. Glutodon gen. nov. is the sixth genus of flat wasps endemic of Madagascar, and the 30th of Pristocerinae.
