Type locality Sudan (Weber, 1942a: 42, illustrated, worker, Imatong Mountains); junior synonym variolosus from Zimbabwe (Arnold, 1949: 261, illustrated, worker & queen, synonymy by Brown, 1975: 23); (see Bolton, 1995) .

Nigeria specimens - TL 2.83 mm, HL 0.59, HW 0.47, SL 0.42, PW 0.34 (in my guides as Cerapachys cribrinodis). Colour dark red-brown, shiny.

In Nigeria collected by me at the base of a cocoa tree and nesting under a log on the ground; also in leaf litter (B. Bolton, specimens determined by Brown, 1975: 62). Brown gave the colour of the types as mahogany to piceous and the Nigeria specimens as black - I saw others of those as dark red-brown

Probably this species also has been reported from Ghana cocoa leaf litter by Room (1971).
