Diagnosis.
Separated from all other African
Dacus
spp. as follows:
Thorax.
Lateral and medial postsutural vittae absent (fig. 64); lateroterga without a xanthine (fig. 68).
Wing.
Costal band incomplete (fig. 70); cell c with an almost complete covering of microtrichia; narrow subbasal raised section of cell br with only a few microtrichia.
Male
. Tergite III with pecten (fig. 65).

Head
(fig. 67). Pedicel+first flagellomere not longer than ptilinal suture. Face, antennal furrow with a very small vertically elongate spot, adjacent lower facial margin; Frons, frontal setae 2, orbital setae 1.
Thorax
(figs 64, 68). Scutum red-brown, without any distinct darker areas; postpronotal lobe concolorous with scutum; notopleural callus white; notopleural suture xanthine absent; lateral and medial postsutural vittae absent. Scutellum dorsally concolorous with scutum, laterally white. Anepisternum with a narrow white stripe from notopleural callus to katepisternum; extended onto katepisternum. Lateroterga without a xanthine.
Thoracic setae
. Anterior notopleural seta present; anterior supra-alar seta absent.
Wing
(fig. 70). Basal cell bc without an almost complete covering of microtrichia; cell c with an almost complete (>90%) covering of microtrichia; cell bm without microtrichia. Narrow subbasal raised section of cell br with only a few microtrichia. Crossvein R-M in apical quarter of cell dm. Costal band reduced; cells c and sc coloured; large apical spot which extends below vein M and includes both R-M and DM-Cu crossveins. Anal streak absent (at most with a trace of colour confined to cell bcu). Cell bc hyaline. Without any crossbanding.
Legs
(fig. 69). Femora orange-brown.
Abdomen
(fig. 65). Orangebrown, without any distinct darker marks; broadest at tergite V (based on
paratype
female;
holotype
male distorted). Tergites I
–
V all fused. Ceromata present.
Male
. Tergite III with pecten, dense microtrichia adjacent end A1+Cu2, and hindtibia preapical pad.
Female
(fig. 66). Aculeus pointed.
Etymology.

) appearance.

Remarks.
The wing of this fly is similar to that of
D. attenuatus
, notably in apical spot size and shape; but if differs in its almost complete lack of microtrichia in the narrow portion of cell br, its extensive covering in cell c, and the lack of a continuous costal band.
