Dorylus (Anomma) gerstaeckeri Emery

Return to main species page Type locality Ghana (Emery, 1895j: 713, illustrated, workers) from Accra .

The original description was of a single worker, TL 8.0; but Emery (1901) received others from Cameroun which were longer, TL 10 mm. These were characterised by a square head about 1/3 of TL; vertex shiny and puncturation sparse; petiole slightly wider than long; overall body stocky (stockier than burmeisteri) and appendages shorter.

Emery's (1895j) description is at . Emery's (1901c) description is at .

Raignier & van Boven (1955) under Dorylus (Anomma) emeryi note comparison with gerstaeckeri; emeryi being bigger TL 12.7 mm; head rectangular, slightly longer than wide, and slightly more than 1/3 of TL (in gerstaeckeri it is slightly less than 1/3).

The Ghana record was from Aburi (F. Silvestri, in Wheeler, 1922). One of the two species studied in Ghana during 1971 by Gotwald (1974). He found it only in the high forest areas, especially in and around cocoa at CRIG, where the almost exclusive prey was earthworms.

Also from Cameroun by Conradt (in Wheeler, 1922).
