Specimen Labels


This ant has been associated with the butterflies Glaucopsyche alexis, Pseudophilotes abencerragus and Leptotes pirithous (Obregon et al. 2015). Pashaei Rad et al. (2018) found this species in Iran in moist to moderate rainfall areas.


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.

Sharaf et al. (2011) - Syntype worker: Madeira, Serra d’Agua (P. E. Schmitz) (Musee d'Histoire Naturelle Genève) [examined]. Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
