Tephritis merzi n. sp., reared from flowerhead galls on Scorzonera kotschyi Boiss., is described from Turkey and placed in the T. pulchra species group. The T. pulchra group is redefined and a key to the seven included species is provided. The best characters for defining the group are the preapical step in the female aculeus and the taxonomic affiliation of the host plants, all in Scorzonera and Tragopogon. All species appear to induce galls, either in the flower heads, or in the upper or lower stem, depending on the species. The galls are unilocular, although several individuals usually develop in them.
