• Note (General): In this paper, I revised the taxonomy of the Tuberculatus quercicola group, myrmecophilous drepanosiphine aphids that are associated with Quercus dentata and Q. crispula in Japan, based on morphometry and molecular phylogeny. This species group has been recognized as T. quercicola with some junior synonyms. Morphometric analysis of 11 morphological characters divided the group into three clusters; i.e., the Q. crispula-associated population, the central Hokkaido group of the Q. dentata-associated population, and the eastern Hokkaido group of the Q. dentata-associated population. MP and ML analyses of the mitochondrial COI gene indicated that samples of the T. quercicola group are separated, with high bootstrap supports, into two monophyletic groups that are associated with Q. dentata or Q. crispula. However, no genetic differentiation was detected between the central Hokkaido group and the eastern Hokkaido group of the Q. dentata-associated population. These results led me to conclude that populations associated with Q. dentata are genetically and morphologically distinct from those associated with Q. crispula, and thus they are in a full specific status. On the other hand, I treated the two local groups of the Q. dentata-associated population as local races based on morphology. I formally redescribed the Q. crispula-associated and Q. dentata-associated populations under the names T. quercicola and T. macrotuberculatus stat. rev., respectively.; (主査) 教授 秋元 信一, 教授 大原 昌宏, 准教授 吉澤 和徳; 農学院（共生基盤学専攻）
