Dorylus (Dorylus) depilis (Emery)
Type locality Cameroun (Dorylus affinis var depilis,
Emery 1895j: 702, male; Forel, 1911e: 254, worker & raised to
species); subspecies clarior (Santschi, 1915c, 1917c: 19,
male) from Zaïre; male and workers known (see Bolton,
1995)  .
Santschi (as a variety of depilis stirps of affinis,
1915c) noted the MALE as differing from depilis in being
dull yellow or rusty yellow, similar colour to affinis,
depilis being notably darker; head brown black; fore wings
more than 16 mm long (15 mm in affinis); pilosity as depilis.
Specimens from Zambezi, by Durand, 1889; and Zaïre, Oubanghi,
by Rev. P. Augustin, 1 male. He noted specimens from Fernando
Po were duller coloured than depilis; and affinis
variety ugandensis had a more rust head which also was
more transverse, with a shorter funiculus segment 2. See
Dorylus
affinis for comparison.
Emery's (1895j) description of the male is at
 .
Forel's (1911e) description of the worker is at
 .
In translation, the latter reads - one worker from Altkalabar has
a different appearance; with similarity to affinis (brevinodosus)
in that the petiole ?? is shorter than wide; also more curved and
wider .
Wheeler (1922) indicates the type locality as "Gold Coast",
i.e. Ghana, also listing it as from Togo, Nigeria
(Old Calabar, by Bates; first in Forel, 1911e) and Cameroun
(Sjöstedt and Conradt), plus several countries eastwards
to Uganda and Tanzania. Forel (1909b, 1911g) found
specimens in the Congo Museum from Zaïre, Kitobola,
by Rovere, and Lukula, by Daniel. |
 The
photomontage is of what appears to be a large media of this
species, from Gabon; Pongara National Park, Pointe Wingombé,
0°19'336"N 0°19'102"E, 27.v.2006, Winkler
funnel of termitarium, collector Yves Braet. The diagnosis is not
certain as the original species description is so poor, but the
petiole is short and wider than long, and the alitrunk overall
longer and more slender than the other species which are described
as workers; the alitrunk appears lacking in pilosity and
pubescence.
