{Pheidole species T5}

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 (Santschi, 1930b).

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.
