(see Bolton, 1995) .

Bolton (1987) refers only to Monomorium salomonis as extra-limital to his study of Afrotropical members of the Genus and gave no description of the species.

Linnaeus' (1758) description is at Arnold (1916: 219) provided a summary; this is at . Stitz's (1917) illustrated description of obscuratum is at . Santschi (1921e) summarised the descriptions of a number of the then varieties; this is at . Santschi (1930a) reported zanoni from Koulouba, Mali, see . Santschi (1936a) gave a further illustrated consideration, this is at . Later, Arnold (1944) attempted to elucidate the efforts of Santschi (1927d); see . See also under Monomorium subopacum.

Egypt records - in former HNS as Aphaenogaster debilis Walker; as Formica salomonis Linnaeus and as Monomorium thorense Mayr; reported by Emery (1877b) as collected at Kantara, Suez, by Issel; in Mayr (1904b: 4) from in sand at Wadi Half on Nile; from a river boat at Suez recorded by Forel (1907a) from Alexandria by Biró; widespread in Egypt in Karavaiev (1911: 4); Wheeler & Mann (1916) from Wadi Gharandel, Sinai; Viehmeyer (1923: 87) as Monomorium salomonis var atrata, collected from the Arabian Desert near Cairo, by F Werner, 4.ii.1914; Menozzi (1929e: 125) reported several workers of sommieri, collected in Sinai, at Wadi Feran & Wadi Scheich, by F S Bodenheimer.

The photomontage is of a worker from Sudan, Khor Tagat, collector Awatif Omer, 2006.

Mandibles smooth; clypeal carinae quite sharply defined; overall sculpturation of dense fine spiculation; general colour dark red-brown
TL ca 3.5 mm, HL 0.96, HW 0.80, CI 0.83, SL 0.80, SI 100, PW 0.42; eye length 0.32 X HW

The photomontage is of a worker from Sudan, Al Fasher; Darfour, West Sudan; collector Awatif Omer.

The photomontage of the type worker of subnitidum is collated from http://www.antweb.org/specimen.do?name=casent0904595.
This seems to be much lighter than the type form and probably also has a relatively long head.
