Nigeria specimen (Taylor, 1979: 15). WORKER. TL 3.4-3.5 mm, HL 0.84-0.90, HW 0.74-0.82, SL 0.40-0.44, PW
0.52-0.56
Occipital corners with a small triangular tooth and an adjacent
denticle. Sides of head behind the eyes shallowly convex, with
minute denticles. Dorsum of head and alitrunk rugoreticulate, with
a longitudinal trend posteriorly. Hairs on clypeus and dorsum of
head are strongly clavate. Remaining dorsal surfaces have numerous
short, fine simple hairs. Pronotum hardly marginate but the
humeral angles are acute and prominent, with a single tooth
laterally close to the junction with the mesonotum. Propodeal
spines moderately long but blunt. In profile the anterior and
posterior faces of the petiole meet dorsally at a near
right-angle. The post petiole has a convex dorsum. Subpetiolar
process is simple with a sharp posteroventral angle.
Subpostpetiolar process simple, short and digitiform.
The holotype and paratype workers, with males and females were collected by Bolton (30.viii.1969) from a nest under the
bark of a moss-covered cocoa tree at the Cocoa Research Institute of Nigeria, Idi Ayunre. My specimens were on
the trunk of a shade tree. |
Bolton
(1974a, Introduction) noted that it, as Cataulacus species
H, probably was collected by Room (1971) from cocoa canopy and
mistletoe at the Mamfe-Mampong cocoa farm in Ghana.
Also known from Zaïre (Bolton, 1974a), and Cameroun
(Bolton, 1982: 356, in key), perhaps at Nko'emvon (D.A.
Jackson).
