Anteon seramense sp. nov. is described from Seram Island (Indonesia). Seram is an island situated in a transition area between the Oriental and the Australian regions. Anteon seramense can be distinguished from the related Australian species A. giluwense Olmi and A. chelogynoides (Perkins) by the different sculpture of the scutum (granulated in A. seramense, punctate and unsculptured among punctures in A. giluwense and A. chelogynoides) and the different distal apex of the protarsal segment 5 (deeply hollow in A. seramense, not hollow in A. giluwense and A. chelogynoides). Anteon seramense sp. nov. can be distinguished from the related Oriental species A. heppneri Olmi and A. thai Olmi by the different shape of the protarsal segment 5 (basal part slightly longer than distal part in A. seramense, much longer in A. heppneri and A. thai).
