476) noted that his original description of
a single specimen from Assinie, Ivory Coast (1892d), was of a medium
size worker with a reddish head. On receipt of several specimens from Cameroun,
collected by L Conradt, Emery found a TL range from 11.0-14.0 mm; head
size range HL 3.0 HW 2.1 to HL 3.6 HW 2.8 mm.
WORKER - no size given by Brown (1976a) but "averages
larger in size" (than troglodytes) [Emery (1899e) gave TL
11.0-14.0 mm], with a higher, more compressed petiolar node. Also
differentiated by 4-segmented labial palps. Colour variable from all
over brown, most commonly with yellow legs; Ghana forest zone
individuals often with a red head and yellow legs.
Widespread in warmer parts of sub-Saharan Africa.
Wheeler (1922) listed findings from Ghana (Aburi, F.
Silvestri), Togo (Bismarckburg, Conradt, Büttner; Misahöhe,
Baumann), Cameroun (Bartsch at ?; Molundu by Schultze;
Mundame, L. Conradt; Soppo, von Rothkirch), and several other
Bernard (1952) described it as less common and more
localised than "haematodus" (troglodytes), more often
found in the forests of Congo westwards than in eastern Africa (where
it was conspicuous in the mountains of Kenya and Mozambique). The Guinea
form, which was very abundant in Lamotte's collections, was notable for
its yellow head (other forms being red-brown), entirely yellow tarsi
(others with brown femurs), and, the propodeum partly black and shiny
(others brown-red and dull). Otherwise the Nimba forms differed little
from the Ivory Coast type, although the thorax was more shiny and the
petiole spine straighter and sharper. The combination led to his
designation of the subspecies flavescens (illustrated scan of
photocopy of photo). This seems to be a form of higher levels, with the
yellow colour being constant across the massif. Findings were from
Kéoulenta, type worker and 2 other, plus 1 queen. Numerous cotype
workers were collected from Yalanzou; Nion; Camp IV, 1000 m; Zouépo,
grassland at 1050 m; Nion crest, 1300 m, scrub; Mount Tô, 1600 m.
Ledoux (1952) reported preliminary research on the
species, including determining that the major food was termites,
although other kinds of small insects found during its surface foraging
were taken. The larger prey were stung but smaller insects were killed
by a simple mandibular strike.
Reported from Ghana cocoa leaf litter and
nesting in dead wood on the ground, also from low scrub, at the Mampong
Cemetery farm (Room, 1971). A single collection of eight workers from
secondary forest at CRIG (23.xii.1991), was made by Belshaw &
