• Combination in Leptothorax (Nesomyrmex): Kempf, 1959d: 415.
• Combination in Nesomyrmex: Bolton, 2003: 272.
• Status as species: Forel, 1899b: 56; Wheeler, 1903d: 222; Wheeler, 1922e: 11; Emery, 1924f: 250; Weber, 1948b: 82; Kempf, 1959d: 415 (redescription); Kempf, 1972b: 134; Bolton, 1995b: 245; Bolton, 2003: 272; Fernández & Serna, 2019: 824 (key), 825 (list) (error).
• Junior synonym of Nesomyrmex asper: Longino, 2006b: 136.
• [Note: Nesomyrmex tristani was treated at species rank by Fernández & Serna, 2019: 824, 825, but their key and list is based only on Kempf, 1959d. The Longino, 2006b publication that established the synonymy is not present in the bibliography of Fernández & Serna, 2019: 881-888, therefore the apparent resurrection of Nesomyrmex tristani is regarded here as an error of omission.]
