{Messor barbarus pedicels}Linnaeus' (1767) description is at {original description}. Latreille (1802c) gave a description of binodis, this is at {original description}. Mayr (1861: 66) gave a key to workers, queens and males, the worker key is at {original description}. Emery (1878b) gave a description, this is at {original description} and {original description}. Emery (1908e) gave a group description of the barbarus group, this is at {original description} [the illustration referred to, Fig. 4, is of M. capitatus nigra]. Emery (1908e) gave a key, this is at {original description}. Emery (1908e) gave a description of barbarus s.s., this is at {original description}. Bondroit (1918: 152) gave an illustrated description, this is at {original description}. Santschi (1929e) is at {original description}.

Emery (1878b) noted the form from Abyssinia [Ethiopia], collected by Beccari (from Keren, also from Bogos by Antinori; Emery, 1877b: 373) had the red parts generally somewhat dull; pronotum subtly rugose, propodeal teeth quite accentuated. Neither the form nor the finding were cited by Bolton (1982) - Mayr's (1961) key separated "Aphaenogaster barbara as having no teeth on the propodeum (metanotum).

Extralimital in Bolton (1982) but recorded from -
Sudan - André (1884b: 245), collected by Dr Paolo Magretti;
Ethiopia - Emery (1881a), Kaka, collector Antinori worker; like the variety from Bogos. Forel (1894b), Ethiopia south, collector Ilg, workers. Emery (1899a), Badditu-Dime, collector Bottego, 1 queen. Forel (1904b) from Godo & Burka, collector Kachovskij, 1 queen,; an unlikely identification is Messor barbarus punctatus (type location India; now a junior synonym of instabilis), in list of Wheeler (1922) from Abuker, Dire Daua & Hara, collector Kristensen.
Somalia - Emery (1892a), Mogadishu, Obbia, Uebi & Ogaden, collectors L Bricchetti Robecchi & Prof Pavesi, workers.
