Type notes: The date '25.xiii.2021' for the 3 paratype workers, 3 paratype queens, and 1 paratype male from the holotype locality is obviously incorrect. According to personal communication with M. Terayama, the correct date is '25.viii.2021'. These specimens thus have the same data as the holotype and only differ in their collection code.
