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). Only two species have been recorded in the The genus Mesocallis Matsumura, 1919 Korean peninsula thus far (Quednau and Lee 2001): (Aphididae: Calaphidinae: Panaphidini) is one Paik (1972) first recorded M. (M.) sawashibae of the least known aphid genera in the world. It (Matsumura, 1917) from South Korea and Quednau is comprised of eight East Asian species in the (1979) added M. (P.) corylicola (Higuchi, 1972), two subgenera: Mesocallis Matsumura, 1919 which was collected in North Korea. Since then, a and Paratinocallis Higuchi, 1972 (Favret 2017, DNA barcoding study on this group revealed that Remaudière and Remaudière 1997). Most of the five distinct groups are distributed in South Korea Mesocallis species occur on host plants belonging (Lee et al. 2017). Between 2001 and 2016, a large to the family Betulaceae, except for one species, number of Mesocallis samples were collected in M. (M.) fagicola Matsumura, 1919, from the family South Korea and examined them together with Fagaceae (Blackman and Eastop 2017, Holman the museum specimens of Mesocallis collected in 2009, Quednau 2003). This genus differs from the North and South Korea between 1985 and 2001. closely related genus Pterocallis Passerini, 1860 by For the freshly collected specimens, molecular its narrow elliptical-formed secondary rhinaria on analyses with the partial mitochondrial cytochrome the 3rd antennal segment and different spinal and oxidase subunit I (COI) were also conducted. marginal setae patterns on the abdomen tergites The results of the morphological examination *Correspondence: E-mail: [email protected] © 2018 Academia Sinica, Taiwan 1 Zoological Studies 57: 17 (2018) page 2 of 20 and molecular analyses identified a total of five diameter of ANT III, URS: ultimate rostral segment, valid species in the Korean peninsula.
