Aenictus weissi Santschi

Type location Congo (Santschi, 1910c: 354, illustrated, worker; Santschi, 1920b: 9, queen, no description) collected at Gomba, by A. Weiss; worker and queen described .

Santschi's (1910c) description of the worker is at ; this seems likely to be a small morph and thus is more slender and has narrow mandibles.

Also from Cameroun at Great Batanga, by G. Schwab (Wheeler, 1922).

Nigeria specimens (as Aenictus species T¹, Taylor, 1980b: 7). WORKER. TL 4.54 mm, HL 0.76, HW 0.86, SL 0.59, PW 0.54
Colour dark orange-brown, legs and gaster lighter, mandibles very dark, overall shiny and polished. Sculpturation of fine, faint reticulation on the anterior pronotum, mesonotum, propodeum and pedicel; overlaid with and partially replaced by fine longitudinal rugae on parts of propodeum and mesonotum. Erect hairs long, fine and abundant. Head widest at the anterior margin, with a distinct occipital margin. The mandibles are massive, with the basal tooth being a huge blunt lobe, the preapical tooth is moderate and the apical tooth is large and slightly blunt. The clypeus has a bidentate median process on the anterior margin. The position of the promesonotal suture is faintly visible on some specimens. Propodeal declivity marginate and concave in profile. The petiole is a flattened dome, with the subpetiolar process trapezoidal, and the subpostpetiolar process acutely triangular.
I collected it from bare ground in a domestic garden and from leaf litter in cocoa at the Cocoa Research Institute of Nigeria, Idi Ayunre.

This specimen is rather more heavily sculptured and more pilose than weissi as described by Santschi but the overall morphology seems a very close match.
