The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

Combination in Odontomachus: Illiger, 1807: 194; in Stenomyrmex: Mayr, 1862: 711; in Anochetus: Emery, 1890a: 63. Senior synonym of quadrispinosus: Roger, 1862c: 289; of rugosus: Kempf, 1964f: 238.

  • rugosus. Anochetus (Stenomyrmex) emarginatus r. rugosus Emery, 1890a: 63 (w.) BRAZIL. Mann, 1916: 418 (m.); Wheeler, G.C. & Wheeler, J. 1952c: 645 (l.). [Unresolved junior secondary homonym of Odontomachus rugosus Smith, above.] Junior synonym of emarginatus: Kempf, 1964f: 238.

The following notes on F. Smith type specimens have been provided by Barry Bolton (details):

Odontomachus quadrispinosus

Holotype worker in The Natural History Museum. Labelled “Brazil” and also with a Farren White label. It is probable that this determination is spurious, a secondary labelling by Farren White, who seems to have had a habit of throwing away original data labels and substituting his own. Also in The Natural History Museum are two quadrispinosus workers with the data, “Para 48/133.” Acc. Reg.: “1848 no. 133. Para. Bt of Stevens. Collected by Mssrs Bates & Wallace.” One of these specimens is sublabelled “172.” I suspect that all three together constituted the original syntype series.
