• Neotype designation: Grimaldi et al., 1997: 12.
• [Note: the designation of a neotype by Grimaldi et al., 1997: 12, appears to be incorrect as Wilson et al., 1967: 8, 9, describe a paratype worker, which should have become the lectotype following the destruction of the original holotype.]
• Status as species: Burnham, 1979: 108; Keilbach, 1982: 277; Bolton, 1995b: 392; Grimaldi et al., 1997: 4, 12 (redescription); Engel & Grimaldi, 2005: 7 (in key), 9; Barden, 2017: 2.
