From Ghana, probably this species was reported from cocoa leaf litter by Room (1971). Collected by pkd at Kade by Majer (1975); and described as widespread by Belshaw & Bolton (1994b), 55 workers from leaf litter samples at eleven sites in the semi-deciduous forest zone.

The Zare finding was a single collection of 7 workers and 8 females taken nesting in "mushroom-shaped termitarium against a tree in the forest" (by Lang & Chapin, in Wheeler, 1922).

Brown (1975: 61) noted that Raignier and van Boven had taken it nesting in hollow twigs in Zare (Epulu and Reserve Floristique de Yangambi, 29 March 1949); also listing silvestrii findings by Ross & Leech, at 26 Km S of Uvira, at 800 m, 10 January 1958. He had found members climbing a tree trunk in sparse single file in a copse in the tall grass Dabou Savanna (47 km west of Abidjan), Ivory Coast - three ants (18 January 1963). He also listed findings from Ghana at Tafo by B Bolton, 26 November 1970. He added that the West African specimens all averaged considerably smaller that those from Congo and the posterolateral teeth on the petiole were generally more developed in the former.

The Antweb worker from Gabon (below) has exactly the same size and proportions, including the eye length.
