pair of teeth with ventral shorter than dorsal. Head reticulopunctate;
alitrunk and pedicel opaque, dull and unsculptured except for a fine
mid-dorsal carina on the pronotum; lateral areas of mesonotum and
propodeum shiny. Dorsum of head with scattered, short, adpressed
spatulate hairs and a lateral fringe of 6/7 curved, broad spatulate
hairs. Erect hairs narrow and clavate on the alitrunk (one pair),
pedicel and gaster. Spongiform appendages of pedicel poorly developed

Brown (1954) simply noted it, as S. rufobrunea,
as being from West Africa.
In Nigeria Cocoa Research Institute of Nigeria,
Idi Ayunre, (B. Bolton) from soil and from a dead log. Also from IITA
(A. Russell-Smith).
From Ghana, Bolton (1983) listed Enchi, Legon and
CRIG (D. Leston), CRIG (B. Bolton; C.A. Collingwood), Mt. Atewa (B.
Bolton), and Mampong (P.M. Room). Listed by Room (1971), as Strumigenys
species 1, from open ground and leaf litter at the
Mampong Cemetery farm. Described as widespread, from their leaf litter
samples (1439 workers plus 31 from soil samples at 20 sites) in the
semi-deciduous forest zone by Belshaw & Bolton (1994b). A single
worker referred to as Strumigenys species F 584 was collected
by Bigger (1981a) by pkd from Amelonado cocoa canopy at CRIG. Not such
specimen was seen by Bolton (1983) but the code number suggests it is
one of the species recorded as collected by D. Leston, the only one
without a well-known name being petiolata.
Ivory Coast records included Issoneu, Man and Tai
Forest (V. Mahnert & J.-L. Perret); Banco Forest and Sassandra (I.
Löbl), Divo and Gagnoa (L. Brader) (Bolton, 1983).
From Cameroun at Nko'emvon (D.A. Jackson), near
Yaoundé (G. Terron), and Batanga (G. Schwab) (Bolton, 1983).
Others Gabon (Makokou, I. Lieberburg, and W.
Gotwald), Central African Republic (Haut Mbomu. N.A. Weber), Angola
and Sudan.
