Strumigenys cacaoensis Bolton

return to key {link to the Hymenoptera Name Server} Type location Nigeria (Bolton, 1971a: 59, illustrated, worker & queen; 1983: 367, illustrated, full-face view), collected at the Cocoa Research Institute of Nigeria, Idi Ayunre, by Bolton in the nest, in a shallow rot-hole in the trunk of a cocoa tree, from which he described the holotype - see below .


Bolton's description (1971a) is at {original description}. Bolton's modern description (1983) is at {original description}.


{Strumigenys cacaoensis} Nigeria specimen (Taylor, 1979: 49). WORKER. TL 2.7 mm, HL 0.83, HW 0.72, SL 0.45.
Head massive with a well developed preocular notch through both dorsolateral and ventrolateral borders. Mandibles with two small preapical; teeth, the ventral apical tooth shorter than the dorsal tooth. Head, alitrunk and pedicel overall finely and densely punctate, coarser on the head. Gaster dully shining. Erect clavate hairs sparse except on the gaster. Head with numerous, small, adpressed spatulate teeth. Spongiform appendages of the pedicel very much reduced. Specimen in CRIN collection from the type series.

In Ghana, Bolton collected several specimens from the stub of a rotten cocoa branch at CRIG, and reported that A.B.S. King thought it occurred in 2-3 of every 1000 pkd samples at CRIG (Bolton, 1971a). Later, a single worker was found in cocoa at Kade by Majer (1975, 1976b), using pkd. Bolton (1983) added collections from CRIG (D. Leston; C.A. Collingwood).

Clearly an arboreal species.
