Postpetiole longer than broad, broader and higher behind than in front, its node distinctly lower than that of the petiole.

I have compared this form with two cotypes from Sierra Leone (Mocquerys), received many years ago from Andre, and a worker from Gaboon (Staudinger). The

differs in its much darker color, feebler sculpture, laterally more compressed petiolar node and in the shape of the mesonotum, which in the typical form of the species lacks the anterior tooth on each side and has only feeble indications of the posterior lobes. Forel has described a variety, rufiventris, from carton nests 3 to 4 cm. in diameter on leaves at St. Gabriel, Lumaliza, and Batiamponde(Kohl), all localities near Stanleyville. This form is larger (3.8 to 4.6 mm.) and, according to Forel, "differs from the type of Andre only in its paler, reddish abdomen and in having the head more elongate and narrower behind." What Stitz has described as a distinct species, gracilis, is evidently nothing more than a subspecies of

ab." This seems to refer to the swelling of the peduncle at the spiracles, a swelling which is visible, though less accentuated in other species of the genus, when the peduncle is viewed directly from above. Forel, however, interprets Stitz's "secondary node" to mean the constricted portion of the segment behind the node. As neither Stitz nor Forel compared their specimens with Andrews cotypes, they were led to regard gracilis as a species.
