The study of the myrmecofauna of Chott Zehrez Chergui, a Ramsar Conservation Wetland in Algeria, has been conducted in three vegetal formations: a halophyte formation of Salsola vermiculata, a psammophyte formation of Retama retam with Aristida pungens, and another halophyte formation of Atriplex halimus. In total, 12 species of ants were listed. The most abundant species are Monomorium salomonis (55.73 %) in the halophyte site near Salsola vermiculata, Messor barbarus (37.82%) in the psammophyte site, and M. medioruber (41.83%) in halophyte of Atriplex halimus.
