Nigeria specimen (as Serrastruma lotti, Taylor, 1979: 45). WORKER. TL 1.90 mm, HL 0.48, HW 0.39, SL 0.34, PW 0.28
Head with reticulate sculpture. Erect hairs generally rather sparse, moderately long and clavate, there is a pair of long slender sinuate hairs at the humeral angles of the pronotum and on the dorsum of the head above the eyes. Pronotum smooth except for a distinct longitudinal mid-dorsal carina. Mesonotum and propodeum spiculate, as is the pedicel. Gaster shiny, base of first gastral tergite with longitudinal striae.
TL 1.9-3.0 mm; the enlarged basal denticles on the mandible are strongly diagnostic, but note the variability of pronotal sculpturation, ranging from almost smooth to strongly sculptured and/or punctate.
I collected it from rotten wood on the ground and from a dead tree branch at the Cocoa Research Institute of Nigeria, Idi Ayunre, Onipe Block; also nesting under dead wood bark on cocoa at Itamerin (neither record was noted by Bolton, 1983).

Found throughout sub-Saharan Africa, plus Madagascar and Mauritius. Pictured in Hölldobler & Wilson (1990, page 121), titled from "tropical Africa" (Bolton, 1983).

In Ghana listed by Bolton (1983) from Mampong (D. Leston), CRIG (D. Leston; B. Bolton), Mt. Atewa (C.A. Collingwood) and Kade (W.H. Gotwald & R. Schaefer). As S. lotti, found in leaf litter, on the ground and nesting in dead wood on the ground at the Mampong Cemetery farm in Ghana (Room, 1971). Collected from leaf litter in the semi-deciduous forest zone, a total of 20 workers, under cocoa at Nankasi, primary or secondary forest at Jachie, Kade and Atewa Forest Reserve, by Belshaw & Bolton (1994b).

Nigeria other records include the Silvestri collection, at Olokemeji, and CRIN (B. Bolton).

From Ivory Coast, at Agboville, Yapo Forest (I. Löbl), Anguédédou Forest (W.L. Brown), Banco Forest (I. Löbl; W.L. Brown), Divo (L. Brader), Issoneu (V. Mahnert & J.-L. Perret), Lamto (W.H. Gotwald & R. Schaefer), Man (I. Löbl; V. Mahnert & J.-L. Perret), Yapo Forest, and Sangrobo (W.L. & D.E. Brown) and Sassandra (I. Löbl).

Other West African records are from Guinea-Bissau, at Rio Cassine (L. Fea, perhaps in 1901); Togo, at Palimé, Klouto Forest (Vit); and Cameroun, at Korup and Nko'emvon (D.A. Jackson), and near Yaoundé (G. Terron).

Bernard (1952) reported an alate queen from Guinea, Mt. Nimba, Crest of Nion, 1300 m; which he felt was close to alluaudi Santschi, from Niger and Kilimanjaro, but, as the queens were badly known in the group, he thought description would be premature.
