Cataulacus difficilisThe photomontage is of a worker from Benin, Béthel, J-F Vayssieres (RVA 3004.3). Slightly larger than the type worker above.

Cataulacus difficilis queenThe photomontage is of a queen from Ivory Coast, Tai, Erena Dupont. Probable queen based on the similarity of the head and pedicel segments.

Note: The photomontage of a worker from Cameroun, part labelled by Bolton (but not listed in Bolton, 1982, where the distribution in the key still has solely "Benin Republic") and on , is a match for Cataulacus taylori.
