specimens (Taylor, 1976: 13). WORKER. TL 5.7 mm, HL 1.24, HW 1.24, SL
1.24 and PW 0.68
Dorsum of head finely striate. Alitrunk striate, coarser on propodeum,
and meso- and metanotal grooves both distinct. Apex of the petiolar
node is emarginate with two blunt teeth. Eyes moderately large, length
0.19 mm. Overall colour castaneous, but legs yellow, shiny.
I collected it from soil and debris aggregations in crevices of mature
cocoa trees at the Cocoa Research Institute of Nigeria, Idi Ayunre;
also from a rotten log (B. Bolton).
Wheeler (1922) listed findings from Ghana at
Aburi (F. Silvestri); Cameroun at Mundame (Conradt), Victoria
(F. Silvestri), Bibundi (Tessmann) and Molundu (Schultze); plus
elsewhere in Congo eastwards.
From Guinea, Bernard (1952) recorded - 2
yellowish workers from Station B 8.24, Nimba; 6 workers with black
cheeks, N'Zo; 4 dark brown workers, Camp IV, forest, 1000 m. He noted
that this is the most common and most variable of the species, found in
¾ of the continent, plus Madagascar.
Brown (1978c) described it as oft-collected and reported
it as ranging throughout the forested regions of West and Central
Africa as far south as northern Angola, southern Zaïre; eastwards to
Uganda and southern Sudan; and north-west to Liberia, at Gibi
(W.M. Mann). He described finding it foraging only at night in the Ivory
Coast (Brown, 1976).
Similar Ghana findings in cocoa and Lantana
scrub at the Mampong Cemetery farm (Room, 1971). Also
from cocoa mistletoe (Room, 1975). Two workers were collected by pkd at
Kade by Majer (1975, 1976b); and it occurred in leaf litter samples
(176 workers, from six sampling sites) at cocoa farms, primary and
secondary forest scattered throughout the semi-deciduous forest zone,
by Belshaw & Bolton (1994b).
