The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.
- pacis. Monomorium pacis Forel, 1915c: 343 (w.) SOUTH AFRICA. See also: Bolton, 1987: 404.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Bolton (1987) - Forel's description of this enigmatic species is too vague to allow even a guess at its correct placement. He says that pacis has something of the appearance of bondroita, but other characters which he mentions indicate that the species is correctly placed in Monomorium.
Features which Forel stresses, which may be of value in recognizing this species, if it is ever rediscovered, include the following.
TL 1.9, smaller than Monomorium leimbachi (a junior synonym of Monomorium rhopalocerum). Profile of head subtruncate in front of the clypeus. Frontal carinae posteriorly forming a strong curve with their anterior lobe, which is situated on the subtruncate region. Eyes with about 15-20 ommatidia, situated on the anterior third of the sides of the head.
