MAJOR - new description TL 3.4-3.9 mm; Spain specimens (Gomez photographs) CI 100 SI 54 OI 13; Kaseh specimens CI 90 SI 58 OI 14
Head in full face view subrectangular or elongate cordate with a moderately deeply impressed occiput
Mandibles small and relatively weak, wholly smooth other than for weak striations on the outer base
Clypeus smooth and shiny with a very weak median longitudinal carina, anterior margin sinuous but only weakly impressed medianly
Frontal carinae very short but very weakly divergent
Antennae with both scapes and funiculi slender and relatively long; funiculus segments 2-7 all no longer than they are wide; apical segment only 1.5 x longer than the penultimate segment
Eye small and weakly ovoid circular (9 facets long X 8 wide); set 1.6 X its own length back from the lateral margin of the clypeus
Hypostoma with solely a pair of quite large lateral teeth; underside of head smooth and shiny (confirmed for the Spanish specimens by K Gomez, pers. commun.)
Alitrunk profile with a moderately domed pro-mesonotum; there is a slightly raised area at the position of a transverse welt on the mesonotum and a steeper area dropping into a very shallow metanotal groove; from above the promesonotum has almost straight sides and has a distinctly marked mesonotal area; the propodeum profile is very weakly convex with very small triangular teeth; from above the propodeum widens behind the metanotal groove, the upper edges are very weakly marginate but there is no longitudinal impression, the propodeum dorsum at the base of the teeth is 0.4 X the maximum width of the promesonotum
In profile, the petiole has a relatively short pedicel which thickens from front to the base of the node; the node is narrow with the posterior face vertical, the upper margin is sharply rounded and not medially impressed
The postpetiole is small and globular; in profile ovoid with lateral processes on the lower posterior margin; in dorsal view it is twice as wide as it is long and the upper surface is evenly ovoid
The gaster is distinctly smaller than the head; from above it is an elongated oval with straight sides; in profile it is a simple elongated oval
The erect pilosity is quite long, fine and quite abundant but generally suberect in such a way as to give the ant an untidy appearance; pubescence short, adpressed and sparse
Generally shiny but with an opaque appearance; there is almost no sculpturation other than the fine longitudinal striations on the anterior one-third of the head
Overall colour pale yellow-brown, the mandibles are variably darker brown; the gaster often has a pattern of ill-defined dark blotches
Gomez (pers.comm) has checked his collection of major workers from the Iberian Peninsula and the Balearic Islands and finds all to have the above arrangement of hypostomal teeth.


{Pheidole pallidula major}The photomontage of what appears to be a major of the type form from Croatia is collated from http://www.antweb.org/specimen.do?name=casent0080860.


{Pheidole pallidula major Spain}The photomontage of what appears to be a good match for the type form is collated from http://www.hormigas.org which deals primarily with the ants of Spain. Others can be seen at, e.g. http://photos.fourmis.free.fr/media/228/Pheidole_pallidula.jpg


{Pheidole pallidula major Kasej Egypt}The photomontage is of what appears to be a major of the type form from Egypt, Kaseh Tourist Village, collected by Mostafa Sharaf, 7.viii.2007. It differs slightly from the above in having somewhat bigger eyes and a longer head, i.e. matching Emery (1915j) illustration and the Finzi (1936) description of recticeps, with a longer head and dark oatches on the gaster.
