Platythyrea modesta Emery
Type location Cameroun (Platythyrea modesta n. sp., Emery,
1899e: 467, worker) collected at Mundame by Conradt - see below
worker and larval
instar described (see Bolton, 1995) .
Emery's (1899e) description is at .
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
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.
