{Pheidole albidula major}The photomontage is of specimens collected in Cameroun, at Banyong Mbo, by Hauke Koch, 11.iii.2006, from debris in Campylospermum axils.
The major clearly matches Santschi's description, with the row of strong hairs on the posterior border of the basal gaster tergites being distinct, also the relatively small eyes, more convex sides to the head, and the colouration, including the visibility of the gut through the gaster cuticle.
The size and arrangement of the teeth or processes on the hypostoma or hypostomal border on the anterior underside of the head are quite different to on Pheidole megacephala. With albidula the arrangement is a pair of well developed submedian teeth, set close to the midpoint, whereas on megacephala there is only a pair of lateral teeth.
The minor (shown below), which Santschi felt unable to distinguish from megacephala has a narrower head, with bristly scapes and a nuchal collar; also there are longitudinal rugae on the genae; the postpetiole is more globular in both dorsal and lateral views.
