Identification

Bolton (1987) - A small yellowish species which seems related to Monomorium australe and its immediate allies, disertum differs from them by having relatively shorter scapes and lacking backward directed hairs on the petiole node. Apart from this disertum appears to have only a single pair of standing hairs on the first gastral tergite in front of the apical transverse row, whereas australe and allies have 2-3 pairs.

Nomenclature

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

  • disertum. Monomorium salomonis var. diserta Forel, 1913j: 216 (w.) ZIMBABWE. Combination in M. (Xeromyrmex): Wheeler, W.M. 1922a: 872. Subspecies of termitarium: Santschi, 1928f: 194. Raised to species and material of the unavailable name petulans referred here: Bolton, 1987: 342.

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

Description

Worker

Bolton (1987) - TL 2.0-2.2, HL 0.52-0·60, HW 0.41-0.48, CI 77-81, SL 0.38-0.43, SI 89-93, PW 0.28-0.31, AL 0.58-0.64 (9 measured).

Anterior margin of median portion of clypeus transverse to shallowly concave. Sides of head extremely weakly convex in full-face view, the occipital margin very shallowly concave. Antennal scapes relatively short, SI < 95. Maximum diameter of eye 0.25-0.27 x HW, with 7-9 ommatidia in the longest row. Metanotal groove feebly impressed. Dorsum of head apparently with a single pair of standing hairs behind the level of the frontal lobes, situated just behind the level of the eyes. The available material is abraded and a second pair may be present close to the occipital margin. Dorsal alitrunk without hairs. Petiole node without hairs, the postpetiole with one backward directed pair. First gastral tergite with a single pair of standing hairs in front of the apical transverse row, situated approximately at the midlength of the sclerite. Head very finely shagreenate to reticulate-shagreenate, mid-dorsally usually with extremely fine longitudinal striolate markings. Pronotal dorsum finely shagreenate to reticulate-shagreenate, the sculpture becoming more obviously reticulate to reticulate-punctate on the propodeum. First gastral tergite with superficial reticular patterning only. Colour pale brownish yellow, the gaster sometimes slightly darker than the alitrunk.

Type Material

Bolton (1987) - Syntype workers, Zimbabwe: Shiloh, 10.v.1913, no. 172 (G. Arnold) (The Natural History Museum; Musee d'Histoire Naturelle Genève) [examined].
