Santschi's (1915c) description is at 
My translation: WORKER. TL 2.5 mm; head a little longer than wide;
rounded up to the eyes; posteriorly without angles; sides of head
slightly convex before the eyes, slightly converging anteriorly.
Mandibles smooth and shiny, partially covered by the clypeus. Clypeus
strongly carinate and convex in profile. Eyes occupying just under the
median third of the head and slightly depressed posteriorly. Scape
surpassing the occiput by about one-third of its length; funiculus
segment 1 one and a half times the length of those following, and twice
as long as wide. Pronotum depressed in a transverse oval; anterior 5/6
with blunt raised borders giving a strongly concave transverse profile.
Meso-metanotum as waisted as in frauenfeldi (European) and
almost as long; spiracles much more raised into conical prominences.
Propodeum with robust lateral lobes, raised and diverging to give
elongated, but rounded cones, as long as the half the basal separation.
Petiole scale very high, inclined backwards and very narrow at the
summit; that terminating in two spines as little longer than the
interval between them; posterior pedicel shorter than the height of the
scale. Gaster rounded.
Colour black; appendages brown, except apical part of scapes and tibiae
which are darker brown. Overall dull matt; dorsum of head and pronotum,
plus gaster shiny and smooth. Front of head feebly reticulated; rest
densely and very finely reticulo-striate longitudinally. Mesothorax
mostly fairly strongly longitudinally striate/rugose. Propodeal
declivity finely tranversely striate. Some long silky black hairs
dispersed on the body, mainly on the gaster. Sparse fine white and
short pubescence, rare on the gaster.
Close to depressa Santschi (from Kenya) and deplanata
from Tanzania, in having the concave pronotum, but separable by its
elongated mesonotum and the petiole scale.
