All forms described (see Bolton, 1995) .

Emery's (1899e) description is at . Forel's (1916) description of grossulior is at .

Forel (1913e) reported the collection of the worker, queen and male by Conradt, from Cameroun, and that he could not say that the small brown male, with hyaline wings, TL 3.0 mm, was of the species.

Wheeler (1922) also had pauciseta from Kilalonga, near St Gabriel, Zaïre, by Kohl; reported by Forel (1915c) as on nectaries of an Acacia (place spelt Kilongalonga).

Bernard (1952) examined the type specimens, including queens, in Forel's collection (in Paris).

TL > 2.5 mm; colour of head and thorax yellow-orange, gaster clear brown, sometimes yellowish anteriorly. Compared with pulchella - antennal funiculus more slender and segment 2 twice as long as wide, following segments 1.5 times as long as wide; petiole similar but gaster flatter and less voluminous than the thorax, finely reticulated and only slightly shiny (after Bernard, 1952, in his notes on pulchella).

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) - see below

Bernard's (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 slightly spatulate.
