Forel's (1902c) description is at {original description}. Bingham's (1903) description, with the queen and integrius, is at {original description}. Donisthorpe's (1942a) description of cooperi is at {original description}.Forel (1911) noted procax as TL 1.3-14 mm; colour rather more brown than type, petiole node somewhat higher; erect pilosity more abundant; from Singapore, collector Haviland. Forel (1913d) noted aharonii as TL 1.3 mm; eyes with about 7 facets; clypeal carinae more feeble than type mictilis, hardly perectible and very obtuse, rest identical; in Menozzi's (1933b) key for species from Palestine, the separation is - 11-segmented antennae (also clavicorne) but head with sides rounded, wholly yellow, eyes small, ca 7 facets [clavicorne with sides of head straight, eyes with more facets, gaster with apex dull yellow].

Egypt records - in HNS as Monomorium (Lampromyrmex) atomus subsp. cooperi Donisthorpe - Donisthorpe (1942a) all forms; one male, one alate queen & 12 workers from Siwa, collected by J Omer-Cooper. Donisthorpe (1947e) recorded "ssp cospeis Donisthorpe" presumably a bizarre printing error for cooperi, as from Siwa, 1 worker, 3-5.v.1935.

{Monomorium atomum}The photomontage is of a worker from Egypt, Mansurah, 3110'N 3135'E; collected by Mostafa Sharaf, 7.viii.2007.

Following the Afrotropical key of Bolton (1987) leads to Monomorium vaguum, also with numerous erect hairs on the alitrunk and elsewhere.

{Monomorium atomum}The photomontage of what seems to be a good match for the limited descriptions, perhaps of cooperi, is of a specimen from Egypt, Masa Mantrouh, collected by Mostafa Sharaf, 2007.
