Nigeria specimens (Taylor, 1976: 9). WORKER. TL 6.6 mm,
HL 1.34, HW 1.15, SL 1.03 and PW 0.95.
Colour generally black, shiny with grey pubescence, extremities,
red-brown. Eye ovoid with flattened anterior edge. Posterior edge
of propodeum with a pair of small teeth. Posterior edge of petiole
with paired lateral teeth and a single central dorsal tooth.
An uncommon, arboreal species which I
recorded twice on cocoa at the Cocoa Research Institute of Nigera, Idi Ayunre.
Wheeler (1922) noted it also from Equatorial Guinea and
Congo. |
Brown
(1975: 45) found specimens to be generally somewhat larger than
the specimen he chose as a cotype (syntype) , TL 7.5, HL 1.38, HW
1.14, SL 1.07, from the collection made by Conradt in Cameroun,
1895. He saw specimens from Kenya (G Allen & Brooks,
Gilgil to Laikipia), Sudan (JG Myers, Khor Aba, Aloma
Plateau), Uganda (Ross & Leech, 10m west of Jinja,
1200m), Zaïre (Ross & Leech at Thysville and 62
miles east of Kibombo, 14 August 1957); Gabon (Makokou, in
rain forest, by I Lieberburg); Ghana (at Tafo, by B
Bolton); and Ivory Coast (ORSTOM, 17 km w of Abidjan, by himself).
The illustration of the petiole (right) is of a specimen collected
near Kimbombo by Ross & Leech.
Collingwood (1985, illustrated), recording it from Saudi Arabia,
noted that it is an active predator with a relatively sharp sting;
and was collected from an exposed rock in bright sunshine.
