specimen (as Cataulacus brevisetosus
Forel, Taylor, 1979: 7). WORKER. TL 3.1 mm, HL 0.78, HW 0.74, SL 0.38,
PW 0.60
Others: TL 3.4, HL 0.90, HW 0.80, SL 0.42, PW 0.60 .
Occipital corners denticulate with a second denticle on the occipital
margin close to the corner. Sides of head behind the eyes usually
minutely denticulate. Dorsum of head and pronotum finely and densely
reticulate-rugose. Remainder of alitrunk usually more rugose
longitudinally, as are the petiole and postpetiole. Gaster dorsally
finely and densely reticulate-punctate. Alitrunk marginate laterally,
especially on the pronotum. Pronotal margin with a row of small or
minute denticles, plus a few also on the mesonotal and propodeal
margins and occasionally on the outer borders of the propodeal spines.
The propodeal spines are short but distinct. The subpostpetiolar
process is a simple blunt spine. On the clypeus and usually on the
remainder of the dorsum of the head the hairs are short and stout,
clavate or sub-orbicular. The remainder of the body has numerous short,
stout simple hairs.
My collections included the 2 paratype workers listed by Bolton (1982)
from cocoa tree 47-16 at Onipe block, Cocoa Research Institute of
Nigeria, Idi Ayunre, where it was seen several times in the 1975 wet
season. Otherwise (as Cataulacus brevisetosus) my staff and I
noted that it was quite commonly found on cocoa and shrub vegetation,
nesting in hollow twigs, and tending Homoptera, it was also found on
coffee (for instance at the coffee plots, SC and S8/2 and on edge
vegetation at W22). Earlier found at CRIN (B. Bolton), and at Araromi
(Bolton, 1974a), and possibly one of the unnamed species in Booker
(1968).
