Xiphydria camelus (Linné, 1758) Specimen examined. Nikko city: 1 ˂, Shôbugahama, Chûgûshi, 26. VI. 2019, S. Maehara (NSMT; cited by Shinohara et al., 2024). Remarks. This species occurs widely from Europe to Japan, but, in Honshu, it is uncommon with the known habitat limited to the highlands of Tochigi, Gunma, Yamanashi and Nagano prefectures (Shinohara and Kameda, 2019; Shinohara et al., 2024). A closely related and more common species, X. eborata, was previously treated as a synonym of X. camelus (e.g., Takeuchi, 1936; Taeger et al., 2010). It is likely that most of the collection records for l X. camelus z in Tochigi prefecture, such as those in Nakamura (2003) and in the references therein, actually referred to X. eborata. Those previous records should be reconfirmed by examining the specimens recorded. Known host plants of X. camelus are Cerasus, Acer, Alnus, Betula, Ulmus, Quercus, Ostrya and Populus (Shinohara et al., 2024).
