Tetramorium semilaeve (André)
Type location Mediterranean
Region (Tetramorium caespitum var semilaeve, André,
1883a: 286, worker; Emery, 1891b: 2, queen; Forel, 1902a: 148, male;
raised to species first by Dalla Torre, 1893: 134; also Bondroit, 1918:
109) - no type images on Antweb (April 2015).
Bolton (1995: 414) lists numerous subspecies but the
whole situation appears in great need of clear resolution.
(1883a) description is among the "Tetramorium
caespitum" varieties at Bondroit's (1918) note is at .

Sharaf list - Material examined: Wadi El-Talaa, St.Catherine (South
Sinai), 15.xi.1998 (2); Wadi El-Talaa, St.Catherine (South Sinai),
19.ii.1998 (2); Wadi El-Arbaein, St.Catherine (South Sinai), 3.iv.1998

This is somewhat similar to the Sinai specimens
collected by M James and diagnosed by BT as Tetramorium
schmidti but that clearly has more numerous erect hairs on the
alitrunk dorsum and is yellow.
This was earlier diagnosed as Tetramorium
brevicorne by Mohamed et al (2001, illustrated) but the
paper by Sanetra, Güsten & Schulz (1999) shows that to have been an
error. Sanetra et al. found that the scape length is not a reliable
distinction for separating workers from caespitum and the
sculpturation of the petiole nodes was a better characteristic. On brevicorne
the postpetiole has more or less evenly distributed reticulate
microsculpture; on caespitum this is restricted to, at the
most, the more basal part of the node; also the occiput on brevicorne
often has rugosity developed into a conspicuous arched pattern.

photomontage is of a worker from among those listed above as
collected by Mostafa Sharaf. Note the wholly smooth petiole and
postpetiole, whereas the head and dorsal alitrunk are finely but weakly
striate; very similar to the jugurtha shown above.
