DNA barcoding reveals a species group of the genus (Diptera, Tephritidae, Tephritinae) with recognition of a new species from East Asia and previously unknown females of (Hardy).

While analyzing DNA barcodes of all the Korean and some East Asian tephritid species in conjunction with the barcode sequences available from BOLD Systems (www.boldsystems.org), the large and taxonomically enigmatic genus was recovered as a monophyletic clade, together with the genera and , which are here synonymized for that reason. Ten major lineages are also recognized within the clade: group, group, group, group, group, group, group, group, group, and group. Here, more detailed taxonomic accounts are provided for the group, including four DNA analysis-recovered members: , , , and . A single morphological synapomorphy is proposed for this species group: the presence of a large mid-anterior dark wing marking in males with associated structural modification (more apically positioned crossvein R-M than in females). Based on the morphological characteristics, two presumptive members that are only known from male specimens are further recognized: and from China. A full description of , and a redescription of , for which only males were previously known, are provided. For all the included species, a taxonomic key, diagnoses, and photographs to aid their accurate identification are given. Finally, is synonymized with and with , and and resurrected from the synonymy of .
