Monomorium pharaonis (L.)

Type location Egypt (Formica pharaonis, Linnaeus, 1758: 580, worker; Mayr, 1865: 90, male; André, 1883a: 338, queen; Forel, 1891b: 164, all forms); junior synonyms antiguensis (Fabricius, 1793: 357, worker) from West Indies, contigua (F Smith, 1858b: 125, queen) from Sri Lanka, domestica (Shuckard, 1838: 627, worker & queen; F Smith, 1851: 119, male) from Great Britain, fragilis (F Smith, 1858b: 124, worker) and vastator (F Smith, 1857a: 71, worker) from Singapore, and minuta (Atta minuta, Jerdon, 1851: 105, worker & queen) from India (see Bolton, 1995) .

Nigeria specimen (Monomorium prossae/?pharonis in Taylor, 1980a: 29). WORKER. TL 2.52 mm, HL 0.57, HW 0.44, SL 0.49, PW 0.28
Colour yellow-orange, apex of gaster dark. Head, alitrunk and pedicel finely and densely reticulopunctate. Erect hairs relatively long and moderately abundant on the head and gaster. Antennae 12-segmented. Sides of head convex in front view with a smooth curve to a slightly convex occipital margin.
Collected in buildings and "sweeping grass" at the Cocoa Research Institute of Nigeria, Idi Ayunre, by B. Bolton.

Others TL 2.2-2.4 mm (Bolton, 1987: 356, illustrated, full-face view, body profile).

Bernard (1952) described it as cited from all of West Africa, even in forest. In Guinea it was abundant at Camp IV (forest, 1000m) of Mt. Nimba; and in the leaf litter sampling of the north-east forest area of the massif (Villiers). Apparently, Lamotte found it near villages and in savanna, and as the related members of the group Pharaophanes were essentially African, there were grounds for believing the ubiquitous pharaonis has its origins in the West African forests, not from Egypt or the Indies as other authors had suggested. (note Bolton, 1987, discarded the name Pharaophanes as nomen nudum).

In Ghana it was found on cocoa mistletoe by Room (1975). Bolton (1987) gave findings from Kibi (D. Leston), Mole Game Reserve (J.C. Grieg), CRIG (A.H. Strickland) and Aburi (P.M. Room). It was described as widespread by Belshaw & Bolton (1994b), who found 17 workers from leaf litter samples at six locations in the semi-deciduous forest zone. Interestingly, Strickland (1948) described it as tending the mealybug, Planococcoides njalensis, but only in the laboratory.

A very successful tramp species with a world-wide distribution, including in heated buildings in temperate countries (Bolton & Collingwood, 1975). Bradshaw & Howse (1984) described it as a mass-recruiting species, using glandular secretions to repel larger ant species.
