DNA barcoding reveals a species group of the genus Campiglossa (Diptera, Tephritidae, Tephritinae) with recognition of a new species from East Asia and previously unknown females of Campiglossa coei (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 Campiglossa was recovered as a monophyletic clade, together with the genera Dioxyna and Homoeotricha, which are here synonymized for that reason. Ten major lineages are also recognized within the Campiglossa clade: producta group, loewiana group, sororcula group, irrorata group, achyrophori group, difficilis group, luxorientis group, magniceps group, arisanica group, and misella group. Here, more detailed taxonomic accounts are provided for the misella group, including four DNA analysis-recovered members: C. coei, C. misella, C. paramelaena sp. nov., and C. melaena. 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: C. pishanica and C. propria from China. A full description of C. paramelaena sp. nov., and a redescription of C. coei, 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, C. favillacea is synonymized with C. coei and C. roscida with C. misella, and C. coei and C. pishanica resurrected from the synonymy of C. misella.
