Nigeria specimens (as Pheidole species
T5, Taylor, 1980a: 25).
Minor. TL 3.11 mm, HL 0.72, HW 0.65, SL 0.73, PW 0.47
Colour orange-brown, head and gaster darker. The only sculpturation is
spiculation on the lateral mesonotum. Erect hairs light, coarse and
moderately abundant, especially on the head. Eyes relatively large.
Clypeus with a medial carina and an almost straight anterior margin.
Alitrunk without visible sutures. This and the Ghana specimen shown
below apparently lack the quite dense sculpturation seen on the above
type forms and are a better match for the mbalensis form
A nest was found in insolated bare earth at the Cocoa
Research Institute of Nigera, Idi Ayunre. No soldiers seen. Found
foraging on the ground and tending aphids.
