Nigeria specimen (as Serrastruma species Bolton collected, Taylor, 1979: 47). WORKER. TL 1.96 mm, HL 0.45, HW 0.36, SL 0.26, PW 0.25. Entire body, except the gaster and central area of lateral mesonotum, reticulopunctate, coarsest on the head. Erect hairs few, most being on the gaster, relatively long, narrow and clavate. Appressed narrow clavate hairs on the dorsal head and alitrunk. Long sinuous hairs at the humeral angles and on the head above the eyes. Colour dull yellow to yellowish-brown.
The specimen drawn was collected by me at the Cocoa Research Institute of Nigeria, Idi Ayunre in 1975 but the details were mislaid. Bolton collected it at Gambari from a tree stump and from under bark of a dead log, although he did not list his findings in the 1983 review.

A single worker was collected by pkd from Amelonado cocoa canopy at CRIG by Bigger (1981a). Since described as widespread (823 workers from 16 sites) in their leaf litter samples in the semi-deciduous forest zone by Belshaw & Bolton (1994b).
