Abstract
AbstractWestern grape rootworm, Bromius obscurus (Linnaeus) is a well‐known pest of grape vines in Europe and North America. We found that all the Korean specimens that have long been known as B. obscurus turned out to be Aoria rufotestacea Faimaire, showing with only about 83% sequence similarity in COI barcodes. The small puncture patterned specimens of A. rufotestacea were initially confused with A. scutellaris Pic, but confirmed to be A. rufotestacea with genitalic characteristics as well as 100% matched COI barcode sequence. Here we describe and compare the morphologically confusing species, B. obscurus and A. rufotestacea, with description of scutellaris‐like wing variation, in detail with adult images and COI sequences.
