Confirmation of the valid specific status of Dolichovespula kuami Kim & Yoon, 1996 (Hymenoptera, Vespidae) based on molecular and morphological evidence.

The taxonomic validity of Dolichovespula kuami, especially in relation to D. flora, has been the subject of a long-term debate. Herein, the valid specific status of the former was supported through an integrated analysis of morphological characters and DNA barcodes. The pronotal rugae and male genitalia of the two species are different, and partial mitochondrial genes (cytochrome oxidase subunit I, COI) indicate that they form significantly distinct lineages. The hitherto unknown male of D. kuami is described for the first time, and a brief discussion of the D. maculata species group is provided. [ABSTRACT FROM AUTHOR]
