Dorylus (Anomma) emeryi Mayr

Type locality Cameroun (Mayr, 1896: 225, all worker morphs; collector Y. Sjöstedt); subspecies pulsi (Forel, 1904d: 170, worker; Santschi, 1923e: 176, major) from "West Africa"; workers only known (see Bolton, 1995; may be in Raignier & van Boven, 1955) .

Mayr's (1896) description is at and . Emery's (1901d) description of pulsi is at . Santschi's (1923e) description of the soldier of pulsi, from Aburi, Ghana, collector F Silvestri, is at .

From Raignier & van Boven (1955), Mayr's original description made comparison with nigricans, syn. rubellus. Raignier & van Boven considered this unfortunate as the closer comparison would be 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); posterior border of head deeply scalloped; scape more slender than nigricans and not reaching mid-length of head; petiole a little longer than wide (Santschi, 1912b); colour red-brown; most of head shiny, the vertex strongly so, with sparse puncturation; body semi-matt, legs shiny. The variety pulsi of Forel (1904) was described solely from media morphs and so has no merit.

Wheeler (1922) listed findings from Ghana (Aburi, by F. Silvestri); Cameroun (Mundame, by Conradt) and Zaire (by Kohl); pulsi was solely from "West Africa".

Dorylus (Anomma) species in wilverthi group

TL 10.13-4.18 mm [Nigeria specimens]. At least four morphs; largest HL 3.47, HW 1.41, SL 1.14, PW 1.14, petiole length 0.87. Humle specimens larger - major TL 14 mm, and six morphs separable.
Colour red-brown. Sculpturation of fine dense puncturation. Erect hairs relatively abundant on gaster, petiole and on dorsum of propodeum. Head widest at mid-length, pronounced domed dorsolateral posterior prominences or tubercles. Antennal scape gradually thickening to a broad apex. Mandibles with a long apical tooth subtended by a denticulate margin running to a basal triangular tooth; numerous hairs on the inner margin. Antennal scapes short and thick, funiculus segments beadlike. Subpetiolar process is a blunt rear-curved triangle.

From Nigeria, the specimens in the CRIN museum were not fully labelled but probably were collected by R.H. Booker at CRIN or Ibadan (Moor Plantation?).
