The south-west PalaearcticGraphipterusserratorgroup is revised. The systematic concept of theG.serratorgroup 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. TheGraphipterusserratorgroup currently comprises 16 taxa. Five new species are described:GraphipterusmagnusRenan & Assmann,sp. n.,GraphipterusmauretensisRenan & Assmann,sp. n.,GraphipteruspiniamitaiiRenan & Freidberg,sp. n.,GraphipterussharonaeRenan & Assmann,sp. n., andGraphipterusstagonopsisRenan & Assmann,sp. n.In addition, five taxa are revalidated to full species status:GraphipterusheydeniKraatz, 1890,stat. rest.(lectotype designated),Graphipterusmultiguttatus(Olivier, 1790),stat. rest.(lectotype designated),GraphipteruspeletieriLaporte de Castelnau, 1840,stat. rest.(the frequently used namelepeletieriis an error),GraphipterusrotundatusKlug, 1832,stat. rest.(lectotype designated), andGraphipterusvaldaniiGuérin-Méneville, 1859stat. rest., and a full species status is proposed forGraphipterusreymondiAntoine, 1953,stat. n.One new synonymy is proposed:GraphipteruskindermanniChaudoir, 1871,syn. n. ofCarabusmultiguttatusOlivier, 1790. Lectotype designations were made forGraphipterusheydeni,GraphipterusminutusDejean, 1822,Graphipterusmultiguttatus, andGraphipterusrotundatus. Neotype designations were made forGraphipterusreicheiGuérin-Méneville, 1859,GraphipterusintermediusGuérin-Méneville, 1859, andGraphipterusvaldaniiGuérin-Méneville, 1859.
