11. Monomorium monomorium Bolton 1987

The sole record of this S European species from Sicily was published by Emery (1914), without mentioning any specific locality. In Italy, M. monomorium presence was mostly recorded in the North (Baroni Urbani, 1971; Castracani et al., 2020). The only Monomorium species we are aware of in Sicily is M. subopacum (Smith, F. 1858), while a record of the tramp species M. pharaonis (Linnaeus 1758) is the consequence of a series of errors on the part of the FaunaEur database (Wetterer, 2010; Schifani & Alicata, 2018).
