Santschi's (1914d) description is at {original description}. Brown's (1954k: 17ff) notes (giving synonymies later reversed by Bolton) are at {original description} and {original description}. Bolton's modern description (1983) is at {original description}.

{Strumigenys rufobrunea}In Nigeria Wheeler (1922) listed it from Olokemeji (F. Silvestri, in Santschi, 1914d). I found two workers in dead wood on ground and a queen at the base of a cocoa tree at CRIN (listed by Bolton, 1983). Ghana records at Legon (D. Leston) and Mampong (P.M. Room) (Bolton, 1983). Collected by Room (1971) from soil under Euphorbia at the Mampong Cemetery farm in Ghana. Described as widespread (1059 workers at 15 sites) from their leaf litter samples in the semi-deciduous forest zone by Belshaw & Bolton (1994b). Ivory Coast records from Adiopodoumé and Man (V. Mahnert & J.-L. Perret), Lamto (W.H. Gotwald) (Bolton, 1983). Togo record from Palimé, Kpime Forest (Vit) (Bolton, 1983).
