[Note: old determinations of Solenopsis molesta, by Smith, F. and others, were certainly misidentifications of Monomorium pharaonis (Linnaeus, 1758). Roger, 1862c PDF: 295, Mayr, 1872 PDF: 152, and Emery & Forel, 1879 PDF: 467, indicate that Solenopsis molesta (Say, 1836), sensu Smith, F., is Monomorium pharaonis.]
