Sjöstedt; and pasteuri (Santschi, 1923e: 265, worker & queen; Brown, 1978c: 556) from Zaïre; all forms described (Bolton, 1995) .

{Anochetus africanus}WORKER - TL 5.7 mm, HL 1.24, HW 1.24, SL 1.24 and PW 0.68
Overall colour castaneous, but legs yellow, shiny. Dorsum of head finely striate. Alitrunk striate, coarser on propodeum, and meso- and metanotal grooves both distinct. Apex of the petiolar node is emarginate with two blunt teeth. Eyes moderately large, length 0.19 mm.

Wheeler (1922) listed findings from Ghana at Aburi (F. Silvestri); Cameroun at Mundame (Conradt), Victoria (F. Silvestri), Bibundi (Tessmann) and Molundu (Schultze); plus elsewhere in Congo eastwards.

From Guinea, Bernard (1952) recorded - 2 yellowish workers from Station B 8.24, Nimba; 6 workers with black cheeks, N'Zo; 4 dark brown workers, Camp IV, forest, 1000 m. He noted that this is the most common and most variable of the species, found in ¾ of the continent, plus Madagascar.

Brown (1978c) described it as oft-collected and reported it as ranging throughout the forested regions of West and Central Africa as far south as northern Angola, southern Zaïre; eastwards to Uganda and southern Sudan; and north-west to Liberia, at Gibi (W.M. Mann). He described finding it foraging only at night in the Ivory Coast (Brown, 1976).

In Nigeria, I collected it from soil and debris aggregations in crevices of mature cocoa trees at CRIN; also from a rotten log (B. Bolton).

Similar Ghana findings in cocoa and Lantana scrub at the Mampong Cemetery farm (Room, 1971). Also from cocoa mistletoe (Room, 1975). Two workers were collected by pkd at Kade by Majer (1975, 1976b); and it occurred in leaf litter samples (176 workers, from six sampling sites) at cocoa farms, primary and secondary forest scattered throughout the semi-deciduous forest zone, by Belshaw & Bolton (1994b).

Locality: Uganda: Mabira Forest; 01°00'00"S 032°00'00"E
Collection Information: Collection codes: SAM-HYM-C002513 Date: 22 Apr 1952
Collected by: Nat. Mus. S. Rhodesia

A specimen of a queen can be seen on the Antweb.org site at http://www.antweb.org/specimen.do?name=casent0101408
Collection Information: Specimen Code CASENT0101408; Locality Zaire (Democratic Republic of the Congo): [Loango Forét du Bavuoge, Museum Paris, Vadon 1911]; Collection codes: ANTC3608. It has the original label "Anochetus sylvaticus" - "Type Sants(chi)" but should not be confused with Anochetus silvaticus described by Bernard (1952) which is a junior synonym of Anochetus traegaordhi. Brown (1978) does not refer to the specimen nor the name "sylvaticus" and Santschi does not seem to have published any description.
