Morphological and molecular identification of C onilepia nigricosta , new to K orea, and L ithosia quadra with their phylogenetic placements within tribe lithosiina ( L epidoptera: E rebidae: A rctiinae)

C onilepia nigricosta ( L eech 1888) is very similar to L ithosia quadra in the superficial appearance of females. We re‐examined their morphologies and analyzed their DNA barcode regions to assess their taxonomic status and phylogenetic relationships with other related genera. Our morphological study confirmed the diagnostic value of the wing venation and the genital structures in both sexes. Our analyses with DNA barcodes showed sufficient genetic divergences ranging from 6.21% to 7.16% between those two species. The phylogenetic relationship using the barcoding region for the members belonging to lithosiina showed that C onilepia and L ithosia are suggested as having strong monophyly compared to other genera.
