• Replacement name for Syllophopsis arnoldi Santschi, 1921c. [Junior secondary homonym of Monomorium arnoldi Forel, 1913a.]
• Status as species: Bolton, 1987: 422 (redescription); Bolton, 1995b: 263; Sharaf & Aldawood, 2013a: 82 (in key).
• [Note: as the replacement name Syllophopsis jonesi was proposed before 1960 (when both arnoldi taxa were included in Monomorium), the replacement name retains validity under ICZN Art. 59.3. Therefore the priority awarded by Ward et al., 2015: 73, is incorrect.]

• Monomorium jonesi
