Taxonomic Notes

Taylor et al. (2018) treat the junior synonym D. oraniensis as a valid, distinct species, but without comment or justification. They also propose Dorylus fulvus saharensis as a junior synonym of Dorylus oraniensis, stating that the smallest of the workers of D. oraniensis from Benin exactly matches the minima worker of D. saharensis (CASENT0911366). These proposals have not been accepted by more recent authors.

Description

Male

Shuckard (1840): Rufo-fuscous, smooth, with long curling hair only on the face, between the coxae and peduncle and at the apex of the abdomen, the head black, except the antennae and mandibles which are castaneous; face and forehead very prominent, this prominence viewed laterally (in profile) as large as the eye; ocelli placed in an equilateral triangle on the vertex, the posterior pair on the posterior declivity of the head closely behind the summit, and these distant more than the diameter of one from the anterior, in front of which the face is deeply sulcated: eyes very prominent and subglobose; antennae setaceous, the scape a little less than one-third the length of the organ mandibles long and slender, slightly curved, rather broad at the base, whence they immediately attenuate, their return in front broadest in the middle, narrowed at each extremity; clypeus furnished between the base of the antennae with a long flock of curling hair, and the labrum with two small round compressed tubercles.

Thorax gibbous in front and at the scutellum, the latter transverse with a longitudinal impression at its apex; metathorax elongate", abruptly truncated at its apex, where it is fringed; mesothorax slightly corrugated in front on each side of the two abbreviated parallel longitudinal central lines, the wrinkles parallel with the suture that separates it. from the prothorax: wings somewhat obscure, with their nervures blackish or dark brown, the radial nervure terminating halfway between the commencement and the inner angle of the marginal cell, and where it loses itself in the colored portion of that cell; the cubital nervure slightly undulated as far as the insertion of the recurrent nervure, beyond which to the termination of the cell it is straight, the recurrent nervure also straight, and inserted at rather less than one half the length of the first submarginal cell; legs castaneous, femora elongate trianguler, acuminated towards the apes, the outline be neath slightly rounded downwards, the trochanters of the four posterior strictly adhering and not projecting beyond the lower outline of the femora.

Abdomen elongate, cylindrical, the peduncle quadrate convex, (its central portion viewed laterally triangular), fringed at the apex, where it has a slight transverse ridge, nearly as broad as the following segment, which and the third are also quadrate, the terminal segment very pilose.
