return to key {link to the Hymenoptera Name Server} Type location Egypt (Dorylus aegyptiacus nov. sp., Mayr, 1865: 76, male; Emery, 1915g: 3, worker, no description but reported as collected with males in Eritrea; as variety of affinis, Emery 1895j: 704) male, Natt, 1858 - see below.
junior synonyms
abyssinicus (Dorylus brevinodosus Mayr var. abyssinicus n. var., Emery, 1895j: 717, worker) from Ethiopia - no images on Antweb (June 2014)

hirsutus (Dorylus affinis Shuck. st. aegyptiaca Mayr var. hirsuta n, var., Santschi, 1917c: 20) from Ethiopia - see http://www.antweb.org/specimenImages.do?code=casent0911326 .

Revived from status of variety of Dorylus affinis, used by various authors since Emery (1892c: lv).


Mayr's (1865) description of the male aegyptiacus is at {original description}. Emery's (1877b: 318) description of "brevinodosus" workers is at {original description}. Emery (1895j: 717) gave a further description, with reattribution of the specimens reported as brevinodosus in 1877, this is at {original description}.


Dorylus aegyptiacus maleThe photomontage is of the type male collated from http://www.antweb.org/specimen.do?name=casent0915641

The hirsutus male (link above) is an exact match.


Dorylus aegyotiacus majorThe photomontage is of a syntype worker of abyssinicus (as in Emery, 1877b) collated from http://www.antweb.org/specimen.do?name=casent0903696

Note: the scales on the Antweb originals do not match. HW on the dorsal view = 1.62 mm, HW in fullface view = 1.80 mm.


{Dorylus aegyptiacus male}The photomontage is of a male from Sudan, Dinder (Aldinder) National Park Centre 11°21' N and 35°02' E along Sudan-Ethiopian Boundary; collector Awatif Omer (S 2-13).

From the Santschi (1917c) key to "Dorylus affinis" males, one can extrapolate more on the male as - TL 20-21 mm, HW < 4.0; upper border of head more or less convex (oblique from the ocelli to the compound eyes); from above the line from the neck to the compound eyes is weakly concave; second segment of funiculus not longer than the first; reddish-yellow; gaster without erect pilosity on segments 3,4 & 5; pubescence thinner than affinis.

The specimen shown here clearly matches those criteria and the type shown above.
