Dorylus (Rhogmus) fuscipennis Emery
 Male
 Type location Ghana (Rhogmus
fuscipennis, n. sp., Emery, 1892d: 570, male only; D.
fuscipennis in Emery, 1895j: 737; Forel, 1909d: 224, footnote,
worker; Forel, 1913h: 349, full worker description), collected by Ch.
Alluaud, at Assinie, now in Ivory Coast
but the area borders on Ghana - no images on Antweb (July 2014). Worker
described in full by Forel (1913h: 349), with collection details the
same as for the male lugubris,
i.e. Aburi, Ghana, by Fisch - see below.

 Emery's
(1892d) description of the male is at  . Emery's (1895j) has a description with
illustrations of the male, which is at  . Forel's (1913h) description of the worker
is at  . Santschi (1919b) notes the male of marginiventris
as with a brighter red alitrunk, the gaster with all segments with a
darker brown posterior border, and the head blackish, see  .
Forel (1913h) reported the worker "not previously
described" -
TL 3.8-6.9 mm; mandibles elbowed basally, then quite strongly curved
and armed with 3 teeth as some distance, with the apical tooth pointed,
long and curved, and the other two large and triangular ; mandibles
strongly and densely puncturate, smooth between the punctures. Head
rectangular, a little longer than wide (up to one-fifth longer); with
straight sides and the occiput deeply scalloped in an arc; posterior
angles somewhat flared, abruptly and feebly rounded; but the occiput is
distinctly flattened. A quite deep occipital notch, continues forward
centrally into the post-clypeal notch. Frontal carinae short and
distinctly separated. Anterior border of clypeus feebly protruding
medially, being a little merged with the frontal carinae. Antennae
10-segmented in largest morph and in the smallest. Scape not reaching
the mid-line of the head. Eyeless. Thorax narrower than the head, with
a single very distinct, quite deep, suture set a little forward of the
mid-point; dorsal profile almost flat; dorsum of propodeum about as
wide as long, subbordered and three times as long as the declivity.
Petiole node one and a quarter times wider than long, slightly narrower
at the anterior. Postpetiole wider than long, not much larger than
petiole. Gaster slightly waisted behind the postpetiole.
Head densely, grossly and deeply puncturate; the puncturation being
slightly less profound on the thorax; and much finer and more spaced
out on the pedicel and gaster. Thorax and pedicel sub-opaque, with
similar sculpture but more reticulate; gaster somewhat shiny and feebly
reticulate; the posterior two-thirds of the head is smooth between the
punctures.
Almost no erect hairs; pubescence semi-decumbent, short, yellowish and
distinct on the appendages; sparse on the body.
Head and mandibles rust or brownish; thorax reddish; petiole, gaster
and appendages yellow or slightly rust.
Specimens from Aburi, Ghana, collected by Fisch with the males
marching in the column. "I have had the worker for a long time but had
neglected to describe it before".
The status of the specimens is confusing if, as Wheeler
had it, the original description of the male was by Emery (1895,
illustrated) from "West Africa, Haitifi?" but Emery (1901c) separated
the major worker from fimbriatus on the grounds of fuscipennis
having antennae with ten segments (11 in fimbriatus; Forel
(1913h) described the worker from Aburi collected by Fisch and yet
Santschi (1919b) purported to describe the lugubris male from
the same location and by the same collector?.
Also known from Congo (Wheeler, 1922).
