Tapinoma luteum (Emery)

return to key {link to the Hymenoptera Name Server} Type location South Africa (Technomyrmex luteus n. sp., Emery, 1895h: 43, worker; Mayr, 1907b: 18, queen; in Tapinoma, Mayr, 1907b: 18) from Makapan
subspecies emeryi (Technomyrmex luteus Emery, subsp. Emeryi n. subsp., Forel, 1910e: 447, worker & male) from South Africa, Natal, Haviland
all forms described (see Bolton, 1995) .


Emery's description (1895h) is at {original description}. Mayr's description (1907b) is at {original description}. Forel's description (1910e) of the emeryi worker and male is at {original description}.


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.

Matches the type form.


emeryi

{Tapinoma luteum 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.


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