Integrated taxonomy of the genus Atlanticus Scudder, 1894 in East China and re-evaluation of morphological characters of eight species (Orthoptera: Tettigoniidae: Tettigoniinae)

Abstract In previous taxonomic studies, identification of Atlanticus species was mainly based on male morphological features, such as cercus, tenth abdominal tergum and subgenital plate. In this study, we systematically revise eight Atlanticus species (61 individuals) in East China. We sequence COI genes of all samples for identification, and compare morphologies and male calling songs. The classification based on male cerci, calling songs, and COI genes is consistent. In contrast, the morphologies of male tenth abdominal tergum and subgenital plate varied among species. In addition, we regard A . jiangyei Liu, Wang & Cheng, 2016 as a junior synonym of A . pieli Tinkham, 1941, and A . helleri Liu, Wang & Cheng, 2016 as a junior synonym of A . kiangsu Ramme, 1939.
