VI.2017, leg. Yong WANG; Shanxi, Jiang Xian (35º29′N, 111º38′E), 1 ♀, 22.VII.1980, leg. Lin-Fu LI. General distribution: China (Beijing, Tianjin *, Shanxi *, Shaanxi, Hubei). Remarks: The assignment of Trachusa cornopes to the subgenus Orthanthidium should be regarded as provisional (Kasparek, 2017). Further studies are needed to show whether it is justified to accommodate T. cornopes and T. formosana, two quite different species, in the same subgenus (Kasparek, 2017).
