The south-west Palaearctic Graphipterus serrator group is revised. The systematic concept of the G. serrator group has undergone many changes during the last two centuries, and several different classifications have been published in recent decades. Here, the numerical taxonomy approach is used with the morphological characterization similarity level of the sympatric taxa in order to delimit allopatrically occurring taxa at the species and subspecies level. A key to the species and distribution maps are provided along with analyses of the conservation status and habitat preferences of the taxa. The Graphipterus serrator group currently comprises 16 taxa. Five new species are described: Graphipterus magnus Renan & Assmann, sp. n., Graphipterus mauretensis Renan & Assmann, sp. n., Graphipterus piniamitaii Renan & Freidberg, sp. n., Graphipterus sharonae Renan & Assmann, sp. n., and Graphipterus stagonopsis Renan & Assmann, sp. n. In addition, five taxa are revalidated to full species status: Graphipterus heydeni Kraatz, 1890, stat. rest. (lectotype designated), Graphipterus multiguttatus (Olivier, 1790), stat. rest. (lectotype designated), Graphipterus peletieri Laporte de Castelnau, 1840, stat. rest. (the frequently used name lepeletieri is an error), Graphipterus rotundatus Klug, 1832, stat. rest. (lectotype designated), and Graphipterus valdanii Guérin-Méneville, 1859 stat. rest., and a full species status is proposed for Graphipterus reymondi Antoine, 1953, stat. n. One new synonymy is proposed: Graphipterus kindermanni Chaudoir, 1871, syn. n. of Carabus multiguttatus Olivier, 1790. Lectotype designations were made for Graphipterus heydeni, Graphipterus minutus Dejean, 1822, Graphipterus multiguttatus, and Graphipterus rotundatus. Neotype designations were made for Graphipterus reichei Guérin-Méneville, 1859, Graphipterus intermedius Guérin-Méneville, 1859, and Graphipterus valdanii Guérin-Méneville, 1859.
