{Platythyrea modesta petiole}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.

Given my specimen from Nigeria and the queen from the Central African Republic, this is aberrant in terms of colour and appears to have a small median projection on the clypeus.
