Tetramorium caespitum v. alternans Santschi ^HNS, 1929

Cagniant (1997), treating this taxon as a subspecies of T. caespitum ^HNS, cites records from diverse sites throughout Morocco. We have recently procured further samples, including the first known gyne (Morocco, Middle Atlas, Reg. Meknes, in CAS), and regard it as a good species which may occur throughout the Maghreb. Some specimens from Tunisia (in NHMB) are very similar, as are workers from the northeastern mountains of Teneriffa .
