Crematogaster (Orthocrema) pulchella Bernard
Type location Guinea
(Bernard, 1952: 230, illustrated, worker & queen). Collected at Mt.
Nimba; 6 workers from forest at Mount Tô; 10 workers (also many cotypes
in alcohol), 1 dealated queen and 1 ergatoid female from same, ravine
1, station B2.41; 4 workers from scrub on the crest of Nion (Lamotte) -
Worker and queen described (see Bolton, 1995). .
(1952) description is at .
TL 2.3-2.5 mm; head, thorax and petiole shiny clear
yellow, with few hairs. Head sometimes a little browner, small and
rounded; antennal scape short, second segment of funiculus just ¼
longer than wide, segments 4-6 twice as long as wide. Petiole longer
than wide, clear yellow, slighty dilated and angular anteriorly. Gaster
voluminous, clearly cordiform, entirely pure black, very shiny and not
reticulated (after Bernard, 1952).
Bernard (1952) remarked how the workers were similar to
those of pauciseta but the queens differ strongly, most closely
resembling Crem. natalensis (from South Africa) (having
examined the type specimens in Forel's collection, in Paris); and
sharing the unusual ergatoid female morph. There were distinct
differences between the queens of pulchella and natalensis.
The ergatoid of pulchella was about twice the size of the
worker but otherwise similar in colour, etc.
Clypeus large and slightly convex, no frontal triangle.
The dorsal alitrunk has very distinct sculpturation with three
longitudinal carinae - the lateral carinae extending back at the
metanotal groove to produce pseudospines. The metanotal declivity is
vertical dropping to a right angle with the propodeum. The latter has a
flat dorsum on a much lower level than the promesonotum. Propodeal
spines long, sharp and slightly upturned. The propodeal spiracle is set
distinctly removed from the base of the spines and is rearward facing
with a sclerotised rim. Lateral petiole thick and spiculate;
postpetiole also spiculate. Pronotal angles each with a distinctive
long thick erect hair. All of the very few erect hairs are long and
