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.
In Nigeria it was an uncommon, arboreal species which I
recorded twice on cocoa at CRIN.
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.
