  Type location South
Africa (Technomyrmex luteus n. sp., Emery, 1895h:
43, worker; Mayr, 1907b: 18, queen; in Tapinoma,
Mayr, 1907b: 18) from Makapan - see below
subspecies emeryi (Technomyrmex luteus
Emery, subsp. Emeryi n.
subsp., Forel, 1910e:
447, worker & male) from South Africa, Natal, Haviland - no images on Antweb (January 2018); note: name preoccupied by Tapinoma emeryi (Ashmead, 1905; see Fisher, B. L. & Bolton, B., 2007, The ant genus Pseudaphomomyrmex Wheeler, 1920 a junior synonym of Tapinoma Foerster, 1850., Zootaxa 1427, pp. 65-68)

Arnold (1915: 152) translated Emery's description
(1895h) as -
"Worker - TL 2 mm; pale flavous, dull, with very fine and pale
pubescence. Erect hairs only on the clypeus and mandibles. Head a
little longer than wide; clypeus widely emarginate in the middle. The
scape extends beyond the occipital margin by about one-quarter of its
own length; declivity of propodeum more than twice as long as its
dorsum. Makapan (Simon)".
On emeryi (Forel), Arnold had -
"Worker - TL 2.7-3 mm; flavous, posterior region of head and posterior
of gaster more or less brownish yellow. Sub-opaque, the sides of the
thorax slightly shining, microscopically rugulose. Pubescence whitish,
very fine and short. Pilous hairs absent. Very similar to Technomyrmex
albipes but differing in the following structural characters.
The head is proportionately wider, and is longer than wide; the frontal
carinae are shorter and less divergent posteriorly, the scape is
relatively longer. The mesonotum is not highest in the middle but at
its anterior margin, sloping thence in a gradual curve to the metanotal
suture. The propodeal dorsum is longer and narrower. The petiole is
shorter and narrower. The gaster widens towards the apex. The eyes are
larger, and the clypeus only feebly sinuate in the middle of the
anterior margin".
Wheeler (1922) listed findings from South Africa, Zimbabwe,
Tanzania [the Mayr, 1907b, report of specimens from
Meru) and Kenya.
Bernard (1952) reported it from Guinea;
several workers from Mt. Nimba, Stations T 32, Zouépo, T 187
and T 5, 1300 m (Lamotte); previously known only from eastern and
southern Africa; specimens with a lower thoracic profile than types.
Note - a specimen from Tanzania,
Mkomazi Game Reserve, 3°54.75' S 37°48.58' E, pkd
collection from Dichrostachys cinerea, 10.iv.1995,
by G McGavin that I earlier listed under this is Tapinoma demissum.

emeryi
 The photomontage of a
syntype worker of emeryi is
collated from http://www.antweb.org/specimen.do?name=casent0903072
This is larger than the type form, which Emery (1895h) gave as TL 2 mm
and appears to match the Congo worker shown below.

 The photomontage
is of a worker from Congo, Iboubikro; collectors
Yves Braet & Eric Zassi. Appears close to the emery worker shown above.

 The photomontage is of a probable male from Sudan,
Rahad Research Area, Kordofan; collector J Mathews (JM 311).
