 Nigeria specimen (Taylor, 1978: 13).
Monomorphic
but with a considerable size range. WORKER.TL 5.89-7.38 mm, HL
1.43-1.87, HW 1.43-1.93, SL 1.37-1.80, PW 1.00-1.40
Colour black with orange extremities, shiny. Erect hairs short, absent
from alitrunk and very sparse on head and gaster. Overall sculpturation
of foveolate reticulation, coarsest on the head, size reducing to a
fine puncturation on the gaster. Alitrunk with sides clearly marginate,
plus paired upturned propodeal teeth. Metanotal groove a wide shallow
depression. Petiole a scale with an acute central node and lateral
processes with bifurcate teeth.
I found it nesting in dead wood on an indigenous tree at the Cocoa
Research Institute of Nigeria, Idi Ayunre.
Also
from the Congo areas (Wheeler, 1922).
Found in Ghana cocoa at Kade by Majer (1975,
1976b), by pkd, apparently two samples with 14-15 workers per sample.
Eight workers were collected by canopy pkd in one area of a block of
mature Amelonado cocoa at CRIG by Bigger (1981a). A specimen from Ghana
is pictured in Hölldobler & Wilson (1990, page 139), and attributed
to Bolton (unpublished).
