Crematogaster (Crematogaster) occidentalis Mayr - new status
  Type location Fernando Po
(Crematogaster
Menileki For. subspec. occidentalis nov. subspec., Mayr,
1902: 293, worker) from Fernando Po - see below  .
Note: Readily distinguishable from Crematogaster (Cr.) menilekii
by the short propodeal spines set part way down the declivity and the
near square dorsal view of the postpetiole (divided into two distinct
globes in menilekii).

Mayr's (1902) description of occidentalis
is at  .
The variety atrigaster
(Forel, 1913h) was described as primarily red with the pedicel, and
gaster black, overall more slender.
Forel's (1916) descriptions of satan and satanula are at  . Santschi's (1921c)
description of viehmeyeri is at  .

 The photomontage
of the type worker is
collated from http://www.antweb.org/specimen.do?name=casent0919672.
TL ca 2.6 mm, HL 0.60, HW 0.60, SL 0.41, PW 0.38; CI 100, SI
69. This appears to be a minor worker; see the larger probable majors of atrigaster and viehmeyer below.

Wheeler
(1922) listed occidentalis from Ghana and Benin (at
Kouandé, by Desanti).
From Guinea, Bernard (1952) reported several
findings of this ant common across much of the continent. The typical,
brown, form was collected at Ziéla, Kéoulenta, sample areas B, F and E;
variety spuria from savanna at Kéoulenta; variety satanula
(yellow, Congo) from site B, Ziéla A3; an alate queen from Ravine I of
Mount Tô seemed to be of this species.
