Camponotus (Tanaemyrmex) aegyptiacus Emery
Type locality Egypt (Camponotus
maculatus aegyptiacus n. subsp., Emery, 1915f: 79, worker;
Menozzi, 1932e: 453, queen & male; raised to species Baroni Urbani,
1972: 130). Note Emery (1915g: 4) listed "C. (M.) aegyptiacus
n.; Ghinda, Nefasit, worker, queen & male"; thus the type location
would be Eritrea; in the 1915f paper he gave no precise location - see
below.

Emery's (1915f) consideration of the maculatus-group
and definition of aegyptiacus is at
Santschi's (1926b) description of sudanicus, from (French)
Congo (Tilho Mission, Region de Zinder, Danagherim Sultanate, by Dr
Gallard, 1910) is at ; his description of claveaui
(from Dakar, Senegal, collected by Claveau) is at ; and his description of infrasquameus
(from Benin (Dahomey), at Kouandé, by Desanti) is at . Santschi (1938a) noted hyskos
was almost identical to the type aegyptiaca but
had much reduced dark patches on the gaster and had a dozen hairs on
the underside of the head.

Note There is no proper original description of C.
aegyptiacus. All we have is Emery's note that the distinct species
has almost entirely yellow legs The allocation by Santschi (1926b) of
the three new varieties to aegyptiacus falls down on the
following:
Larger - claveaui TL 13-14 mm, HW 3.8 mm (type
3.3 mm), hind tibia length 4.5 mm; minor head narrower and longer,
scape 2.9 mm, surpassing the occiput by about half its length, head
shape straighter behind the eyes
Smaller and clearly quite different - infrasquameus
TL 6.5-11 mm, HW narrower (than the type at 3 mm), scape longer ( minor
scape length 2.9 mm, occiput more concave, minor with narrower dark
banding on the gaster, head much narrower, petiole scale much lower.
Baroni Urbani (1972: 131) ignores the size variation
altogether, taking colouration as a simple matter of variation. This
simplistic approach clearly has to be questioned.
In the specimens shown below the major TL is about 13
mm, HW about 2.6 mm, hind tibia length about 2.9 mm. The minor
has a high narrow petiole scale and the short scape ca 2 mm, as implied
by Santschi. Collingwood also had the specimens from Saudi Arabia as
with HW 3.5 mm or less.

From Egypt, it
was illustrated by Savigny (Audouin, J.-V.
1825-27: Plate 20 Fig 8).
Egypt records - Alfieri (1931: 48) listed 52
collections in the 1925 survey, in Cairo and its suburbs, from the
Provinces of Charkieh, Fayoum, Assiout and Keneh; Santschi (1938a: 40)
also listed numerous findings; Donisthorpe (1942a) listed numerous
specimens from the Siwa Oasis area, all collected by J Omer-Cooper,
June-July 1935; he later reported further specimens of all forms from
Siwa, Siwa depression, Koreshid, Zeitoun and Abu Sharuf (Donisthorpe
(1947e).

Emery (1915f) laid
stress on the type form of maculatus
(as described by Linnaeus from the Bank's Collection in London) having
ferruginous femora and black lower legs, whereas the form common in
Egypt and neighbouring countries had completely pale legs. Collingwood
(1985), recording it from
Saudi Arabia, noted that in profile the dorsal outline of the alitrunk
is more or less continuous; the gaster with a distinct pattern of 2 or
3 yellow blotches, which merge into each other laterally giving an
irregular banded effect; gula hairs present but not numerous; smaller
species, HW 3.5 mm or less. He added that it is a common north east
African species; mainly active at night when foragers can be seen
flitting very rapidly over the ground in search of food; the minor
workers are very pale.
