description (1987) is at
WORKER - TL 1.3-1.7 mm; colour usually dull yellow to
light brownish yellow, some Cameroun specimens darker medium
brown (Bolton, 1987: 421).
Listed by Bolton (1987) as a minute leaf litter species
found at IITA, Nigeria (A. Russell-Smith). In earlier versions
of this website, I referred to finding it ground nesting and foraging
at CRIN (specimen in my voucher collection apparently missed by Bolton;
in my guide as Syllophopsis species 2), that identification (by
me) clearly was wrong.
From Ghana, at Mampong (P.M. Room; D. Leston),
CRIG (B. Bolton) and Axim (C.A. Collingwood) (Bolton, 1987). It was
described as widespread by Belshaw & Bolton (1994b), who found 1475
workers from leaf litter samples, and 242 in soil samples, at sixteen
locations in the semi-deciduous forest zone. In Ivory Coast, at
Dropleu, Issoneu and Man (V. Mahnert & J.-L. Perret in October
1980); Cameroun at Nko'emvon (D.A. Jackson); also Gabon.
