Western grape rootworm, Bromius obscurus is a well-known pest of grape vines in Europe although it was originated from America. Although this species was originally described in America, its distribution became pandemic and are known to occur in Korea (포도꼽추잎벌레) as well. We recently compared their morphologies and COI sequences and found that the Korean species is not B. obscurus, but a similar species either within the same genus, or possibly in a different genus of Eumolpinae of Chrysomelidae as their sequence similarity is less than 90%. Preliminary comparison between the two species is given with outer morphology and COI barcode sequences.
