Minor description (translation of Mayr 1896 by Marcus Stuben)
Worker. Length: 3mm. Brown, the mandibles light brown; funiculus, joints of the legs and the tarsi clay-coloured / luteous [lehmgelb]. The whole body and the tibiae moderately covered with a long, erect pilosity, without pubescence.
The mandibles basally more or less longitudinally striated, distally smooth and shiny, the masticatory margin finely denticulate, distally with 2 very distinct teeth. The head is smooth and shiny, at the frontal carina [Stirnleisten] and between these and the eyes slightly striated, the sides of the head and at the backmost fifth part or sixth part of the head with fine leather-like wrinkles. The shape of the head close to the “foramen magnum“ differing from that of Pheidole megacephala in being more constricted (narrower). The clypeus is entirely lacking a carina and its frontal margin is not emarginated. The scape of the 12-segmented antennae exceeds the hind margin of the head by about 2/5 of its length, all segments of the slender funiculus are very clearly longer than broad, just the second segment is as long or a little longer than broad. The medial notch is distinctly impressed. The eyes are a little in front of the midpoint of sides of the head. The alitrunk is finely reticulate-punctate; the pronotum has a smooth shiny disk and two sides, it has two small humps [Höcker] at the top of the rear; the mesonotum is elongated and has in the middle a not or a just shallowly impressed transverse margin [Quereindruck]; the base or dorsum [Basalfläche] of the propodeum is longer than broad, not marginated on the sides [seitlich nicht gerandet] and at the rear has 2 erect , nearly parallel short spines, which are slightly shorter than their distance between each other at their basis. The second segment of the rather smoothed petioelus is slightly longer than broad, from the front to the middle gradually broadened, and in the middle laterally rounded. The gaster [abdomen] is smooth and shiny, at its basis sometimes with fine leather-like wrinkles.

Pheidole aurivillii minorThe photomontage is of a minor worker from Benin, Korobouro; collector J-F Vayssieres (RVA2699). This and the others fron Benin are slghtly smaller and perhaps have denser spiculate sculpture than the type minor and that (below) from the CAR.


Pheidole aurivillii minorThe photomontage is of a minor worker from the Central African Republic, Ndoki, Sangha; collector P Moretto.
