Dorylus (Dorylus) braunsi Emery
Type locality Liberia (Emery, 1895j: 781) collected by H.
Brauns; subspecies anceps (Forel, 1914d: 215, worker) from
Zimbabwe; junior synonym impressus (Stitz, 1910,
127, workers; synonymy Santschi, 1924b: 198) from Equatorial
Guinea; workers only known (see Bolton, 1995)
 .

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.

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. |
