Forel's (1909b, 1915c) description is at 
Forel's (1909b) description of winkleri was -
TL 2.8-4.6 mm; larger than the type - of africana - with a more
compact central mesonotal carina; propodeal spines more robust and
petiole node larger and more rounded.
The winkleri were from cocoa farms in Victoria, Cameroun,
collected by Winkler; others were among Crematogaster specimens
E. André had asked him to identify from Congo, collected by Father
Hermann Kohl and Professor Laurent, botanist, from in the stems of
plants. These included this species (as winkleri), samples No.
104, 105, 106 and 108, from Olombo, Eala and Bokala in hollow twigs of Barteria
dewvrei, Cuviera angolensis and Plectroctonia laurentii.
Forel (1911f) later reported winkleri from Zaïre, Kasai, Kondué
by Luja.
Later, Forel (1911e) had  .
The queen was described by Forel (1913a: 124) as L
8.0-8.5 mm; matt, densely longitudinally striate with reticulation
between the striations; gaster subopaque, reticulate and
punctate; propodeum with paired obtuse teeth; petiole a little wider
than long and a little wider anteriorly; postpetiole without any trace
of a groove, slightly impressed posteriorly; pubescence distinct;
black; legs and scapes brown; funiculi, mandibles and legs reddish;
wings quite strongly brownish; Kasai, Congo, Luja & Zimbabwe,
Arnold.
The placement under Crematogaster kohli by Santschi (1937g) appears to be have been wrong.

On fickendeyi, Forel (1913a) wrote - worker, TL
3.3-5.3 mm; differing (from winkleri) in having a very wide,
almost circular, petiole, much wider than the postpetiole; the latter
is also distinctive with a superficial longitudinal groove; entirely
black, as the gaster; Victoria, Cameroun, by Fickendey; also collected
at Kasai, Kondué, Congo, by Luja.
Forel (1916) separated winkleri n var transversiruginota
as - Workers, TL 3.2-4 mm; a big as the biggest winkleri but
distinguished by having the mesonotum strongly truncate and the dorsal
carina short; the dorsum of the propodeum has strong transverse rugae;
petiole a little wider anteriorly; from Motombe on the Okiavo River;
taken from a carton nest some 50 cm tall.
Wheeler (1922) included other findings of winkleri
from Nigeria (Oni Camp, east of Lagos, by W.A. Lamborn; Old
Calabar, by Bates, see below) and Cameroun
(Johann-Albrechtschöhe, by Conradt).
In the Congo Basin, Bequaert (1922, p 407) cited it as
collected by Father Kohl from in myrmecophilous plants. He also
reported it from the low tree or shrub, Sarcocephalus species
(p 459) - seen in the Ituri Forest and near Masongo (Zaîre). The
domatia were inconspicuous (illustrated), being no more than a very
slight swelling on the upper half or two-thirds of an internode. When
inhabited, ants often had made a small circular opening just below the
node. All ants observed were small Crematogaster; those
identified were kohli (as Crem. africana ssp
winkleri variety fickendeyi) - "a form commonly found
nesting in other places". The ants had established regular colonies in
the cavities with a queen, workers and brood, together with coccids
fixed on the inner walls of the stem. Another host plant was Plectronia
laurentii.
