Arnold (1915: 120) had the following (translation?) of
Emery's description (1895).
This species is exceedingly similar to helvolus, differing from
it chiefly in the shape of the head, which in the major and larger
minors is distinctly wider in front than behind, the sides converging
posteriorly, so that the occipital margin is rendered shorter. The
puncturation of the vertex is also shallower and sparser in all the
minors, but in specimens determined as braunsi for me by Dr.
Forel, I do not find that the smallest workers (2.8 mm.) have the sides
of the head entirely smooth as described by Prof. Emery. The majors do
not exceed 8 mm in length. The colour, especially of the larger forms,
is slightly darker than in helvolus; otherwise similar to that
species.
Bulawayo. (R.M. and G.A. colls.)
Arnold (1926) had a translation of Forel's (1914)
description of anceps; this is at  . Note - Forel (1914d) added that he had a
specimen from Cameroun which had a head that was much longer and bigger
than Emery had attributed to the type.

 The
photomontage is of a type worker collated
from http://www.antweb.org/specimen.do?name=casent0903701
Clearly a small media worker, TL ca 4 mm, and not the major with TL 8 mm given by
Emery (1895j).

 The
photomontage is of the type worker of anceps
collated
from http://www.antweb.org/specimen.do?name=casent0905918
Probably a media worker, TL ca 5.5 mm, as Forel (1941) gave the largest
as TL 6.2 mm.
