Specimen Labels

A grain harvesting species (Collingwood and Agosti 1996). This taxon belongs to a group of species widespread in the Middle East and Central Asia, where several to many still unreviewed forms occur. Its westernmost known range reaches Sardinia and Corsica. It is common in central and southern Italy, and in the Balkans (Rigato & Toni, 2011).


Collingwood and Agosti (1996) - HW 2.5-2.9; EL/HW 0.16-0.19. This species differs from Messor semirufus and related species by the shape of the pronotum which is mildly flattened dorsally and expanded laterally into a protuberant boss at each side. This is a constant and characteristic feature and most easily seen in slanted profile.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.

A very common grain-harvesting ant found on all of the Greek islands, on the southern Balkan mainland, in South Italy and the Mediterranean islands of Corsica, Sardinia and Sicily but not in Malta or the Balearics. It has also been taken locally in Tunisia but its occurrence so far south as Oman is a surprise. However, Tohme (1968) and Tohme & Tohme (1981) recorded it as the synonym Messor concolor from Lebanon and Syria respectively. (Collingwood and Agosti 1996)
