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. 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.
