Nigeria
specimen (Taylor, 1980a: 29) - WORKER. TL 2.89 mm, HL 0.78, HW 0.62, SL
0.67, PW 0.37
Others TL 3.2-3.9 (Bolton, 1987). Colour orange-brown, gaster black.
Head, alitrunk and pedicel densely spiculate. Few erect hairs on the
gaster, pedicel and the anterior of the head; short but sparse pilosity
all over.
Widely distributed throughout Africa north of the
Equator, principally in drier areas; in forest zones on paths where
open to the sun. Wheeler (1922) listed it also from Guinea (Kindia
and Mamou, by F. Silvestri) and Ivory Coast (by Lohier). In Guinea
the Mt. Nimba surveys found it to be abundant in savanna and forest,
although not above 1200 m (Bernard, 1952).
Nests in open ground, in Nigeria, I found it not
common at CRIN, but forages on the ground and will tend aphids on cocoa
flowers near ground level. Bolton (1987) listed CRIN (B. Bolton, B.
Taylor), Mokwa (C. Longhurst), Bakura and Sokoto (E.A. Mill) and near
Lake Chad (J.C. Deeming).
In Ghana from Mole Game Reserve (J.C. Grieg),
Bolgatanga, Mampong and Tumu (P.M. Room) (Bolton, 1987). Listed from
open ground at the Mampong Cemetery farm by Room (1971). A single
worker was found in leaf litter under primary forest at Mankrang Forest
Reserve by Belshaw & Bolton (1994b).
Otherwise from Togo, at Tové (B. Dufour); Liberia,
at Monrovia (no details); and Cameroun, at Great Batanga and
Metet (G. Schwab) and Nko'emvon (D.A. Jackson).
