Camponotus ruber Emery 1925 This species was recorded so far from Egadi (Scupola, 2009) and Aeolian Islands (Schär et al ., 2020). Previous records of C. sicheli Mayr 1866 from Sicily may all have to be attributed to C. ruber , but no localities were reported by Forel (1879) or any subsequent author (Poldi et al ., 1995; Schifani et al ., 2021a; see under C. sicheli ). We confirm C. ruber at least from NW Sicily , a region that was particularly interested by Maghrebian faunal influences (Schifani et al ., 2020).
