 Santschi's (1915c)
description is at  . My translation: MALE. TL 4.5 mm; head,
excluding the eyes, rectangular, a quarter longer than wide, with a
straight posterior border. Eyes very convex, occupying anterior
three-quarters of the sides of the head; interval between the eye and
the lateral ocellus equal to the ocellus diameter. Clypeus border
tranverse medially, raised centrally in a rounded lobe and carina of a
fine median lamella in its posterior half. Frontal carinae lamellate,
arcuate, strongly convergent posteriorly where they form a slightly
raised median ridge reaching the near to the median ocellus and on each
side delimiting a shallow antennal scrobe. Scape reaching the median
ocellus, as long, with the condylar bulb, as the second and third
funiculus segments combined; first funiculus segment no longer than the
scape width; following segments subequal and three times longer than
wide. Mandibles without teeth, internal angle very rounded, external
border feebly concave in the basal half and slightly convex apically.
Mesonotal suture impressed. Mayr's notch distinct. Propodeal dorsum
convex, declivity concave and distinctly edged, longer than dorsum,
smooth. Wings hyaline with veins and fringe pale yellow; closed cubital
cell, radial cell incomplete. Petiole as high as long, node globulose,
as wide as long; with subpetiolar appendage a truncated forward
pointing tooth. Postpetiole with a small ventral anterior tooth, node
as high as other gastral segments, but clearly slimmer, distinctly
longer than wide and not more constricted posteriorly. Genitalia
hidden. Colour reddish brown; appendages and gaster reddish yellow;
dorsum of gaster a little darker brown. Head and thorax with large
irregular puncturations, more or less confluent on a smooth ground;
puncturation of gaster finer and more spaced; sides of propodeum
rugulo-reticulate. Fine long, decumbent pilosity, more erect on gaster;
legs and antennae pubescent, latter very finely.

NOTE - Bolton (1990a
and 1990c) provided an
illustration of the lateral alitrunk and gaster of what is labelled as
this species and is a worker. Where it came from and who determined it
without any description was not explained. In the first paper he writes
of there being two species from Africa, so perhaps it can be
assumed that the form from
