Cataulacus taylori Bolton

Type location Nigeria (Bolton, 1982: 364, not illustrated, worker) .

Bolton's description is at .

First description (as Cataulacus difficilis, Taylor, 1979: 9). WORKER. TL 3.33 mm, HL 0.86, HW 0.78, SL 0.44, PW 0.64 (in my guide )
Occipital corners of head each with a pair of small, acute triangular teeth. The dorsum of the head is reticulate-rugose with the rugae longitudinal anteriorly. The dorsum of the alitrunk is longitudinally rugose, and the first gastral tergite is reticulate-punctate. All dorsal surfaces have stout, blunt erect hairs. The sides of the pronotum are marginate and strongly denticulate, but the remainder of the alitrunk is more weakly and sparsely denticulate. The propodeal spines are short and acute. There is a strongly developed mesokatepisternal tooth (on the lower part of the lateral alitrunk overhanging the front tibia), which is triangular, acute and visible when the alitrunk is viewed from above. The subpetiolar process is simple and the subpostpetiolar process long and digitiform.

Bolton separated the holotype and a paratype found at the Cocoa Research Institute of Nigeria, Idi Ayunre, but from different locations on the plantation. I took the first worker from the Onipe 1/1 block, the first Nigerian record of what I identified (from Bolton, 1974a) as Cataulacus difficilis. The latter was separated by Bolton on the basis of a single specimen, taking the mesokatepisternal tooth as definitive. The collection details given by Bolton, however, do not match my own field note book, especially as I had stopped collecting before 24.v.1976 and appear not to have been in the field on 25.vii.1975.
