The Mesocallis Matsumura (Hemiptera: Aphididae) of the Korean peninsula with descriptions of two new species. Zool Stud 57:17. doi:10.6620/ZS.2018.57-17. Yerim Lee, Mariusz Kanturski, and Seunghwan Lee (2018) This study reviewed the aphid genus Mesocallis from the Korean peninsula. A total of five species are recognized using morphological and molecular evidence, including two new species, Mesocallis (Mesocallis) carpinicola sp. nov. and M. (Paratinocallis) occulta sp. nov., one newly recorded species, M. (M.) pteleae Matsumura, 1919, and the two species M. (M.) sawashibae (Matsumura, 1917) and M. (P.) corylicola (Higuchi, 1972). Species description, illustrations and distributional and biological data were provided for all Korean Mesocallis species along with a pictorial key. Pairwise distances, a neighbor-joining tree and a median-joining network are also given. Key words: Aphids, Biodiversity, Calaphidinae, COI, New record, Panaphidini. BACKGROUND (Quednau 2003).
