Frontal carinae less prominent, space between less concave; whole of head flatter, eyes smaller. Propodeal dorsum longer; petiole node larger; gaster slightly enlarged posteriorly, but less than in subgenus Rhogmus. Legs shorter. Wings darker brown. Pubescence less on thorax, less dense and more woolly, resembling grey brown felt. Specimen from Zaïre, Katanga, Mawambi, by Lemaire; rather bigger than type of emeryi. Zaïre , Kenya & Uganda -  stanleyi

8 {Dorylus nigricans male}Santschi (1937b) noted - these males are much duller than those of the race burmeisteri, the wings are clear, except for the radial cell, but the nerves are blackish (Forel, 1909b, gave HW 5 mm, PW 6, gaster width 5.6 mm); the original description gave "Schwärzliche Aemsenwespe [blackish wasp], nigricans, brunneo-holo-sericeus, abdominis petiolo acetabuliformi. Lange : Einen Zoll [ca TL 25 mm] bis einen Zoll und drei Linien [TL 28.4 mm]". The specimen was a little bigger than the already known species Dorylus (Dorylus) helvolus and without hairs; the wings of nigricans were smoky black with black veins. Posterior border of petiole concave .
