integrium (var. integrius
n. var., Forel, 1902c: 210, worker & queen)
from India - see http://www.antweb.org/specimenImages.do?code=casent0908765

Forel's (1902c) description is at . Bingham's (1903) description, with the
queen and integrius, is at . Donisthorpe's (1942a) description of cooperi
is at .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].
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.

The photomontage is of a worker from Egypt,
Mansurah, 31°10'N 31°35'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.
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.
