Diagnosis. Wing length (mm): ♂ forewing 30–36, hind wing 26–30; ♀ forewing 31–35, hind wing 27–29. Dark brown to black species with two lateral yellow markings on each side of mesoscutellum; anterior edge of this marking is oblique and not perpendicular to the axis of the body. Veins black. Lateral spines of base of abdomen stout, stronger than in D. caviceps . Gonarcus with a dorsal V-shaped marking ( Fig. 129 ).

Redescription. Head. Labrum, clypeus and genae light yellow. Face yellow with a brownish to dark brown transverse stripe below base of antennae. Face with white setae. Vertex brown with mixed grey and black setae. Thorax ( Fig. 94 ). Pronotum light brown with discal surface black. Mesonotum: prescutum brown with two yellowish round markings. Mesoscutum brown bordered with yellowish. Mesoscutellum dark brown to black with two posterior conspicuous yellow markings. These markings are approximately triangular, with anterior margin oblique. Metanotum: metascutellum brown with two postero-lateral yellowish markings. Lateral surface brown and yellow ( Fig. 72 ). Typically in mesonotum the anepisternum is brown, basisternite brown and yellow, katepisternum brown variably suffused with yellow, anepimeron yellow with anterior margin brown, katepisternum brown; in metanotum the anepisternum is brown suffused with yellow discally, the basisternite and the katepisternum brown and yellow, anepimeron yellow with a ventral brown marking and katepisternum brown with the dorsal margin bordered with yellow. Legs. Femora and tibiae yellow with black longitudinal lines ( Fig. 72 ). Wings. Membrane hyaline. Some specimens have the costal field and the apex suffused with pale brown. Abdomen ( Figs 73, 74 , 79, 80 ). Brown. First abdominal tergite of male with posterior and dorsal surface of dorsal expansions yellowish ( Fig. 73 , 79 ). Lateral expansions variably globulous with stout black erect setae ( Fig. 73 , 79, 80 , 94 ). Second abdominal tergite with a tuft of slender erect setae ( Fig. 73 ). Lateral surface of second and third abdominal tergites covered with short, stout spine-like black setae. Third abdominal tergite with a dorso-longitudinal darker line and the slits variably marked with brown. Abdominal sternites III to VI with longitudinal black stripe norrowed anteriorly ( Fig. 74 ). Ectoprocts yellowish with anterior round dark marking and posterior margin largely bordered with dark brown ( Fig. 75 ). Subgenital plate variably bulged, largely bordered with dark brown, posterior margin with blunt tip ( Fig. 75 ). Male genitalia. Gonarcus-parameres complex as in figures 81, 82, 129–132. Gonarcus brown, light in colour dorsally. Bulb surface variably wrinkled and whitish with a darker V-shaped marking. Parameres long. Carena well developed.

* This specimen is in a poor state of preservation. The thorax is fractured between the meso and the metathorax and the abdomen, of which the apical part is lacking, has been reattached to the thorax by its caudal extremity. I tentatively identify it as D. transvaliensis .

Distribution. The species is distributed throughout eastern Africa from the Republic of South Africa to Sudan ( Fig. 139 ).
