This ant has been associated with the butterflies Glaucopsyche alexis, Pseudophilotes abencerragus and Leptotes pirithous (Obregon et al. 2015).

Identification

Sharaf et al. (2011) - As Forel (1895) stated in his original description that the sides of the head are less convex than the other species. Other specimens from Spain and Madeira are illustrated by Taylor & Sharaf (2007). Those are a darker red-brown than the, probably faded, syntype.
