Redescription. MALE ( Fig. 1 View FIGURES 1–10 ). Head. Eye bare; holoptic, touching for at least 4 times length of ocellar triangle, facets enlarged in dorsal half. Frons shining black; with black-brown pollinosity; dispersed pilosity of short pale pile, along dorsal margin longer black pile; rugose area shining black, occupying half of entire width and at least three-fourths of height of frons. Face shining black; with greyish pollinosity dorsally and ventrally of facial tubercle; dispersed pilosity of short pale pile; facial tubercle elongated, moderately pronounced. Three tiny silvery maculae present along inner margin of eye. Occiput dorsal third shining black; ventral two-thirds with conspicuous silvery pollinosity, ventrally with dispersed pale pile. Antennal segments black to black-brown; arista yellow-brown, in basal half with long pile equal to width of pedicel.
Thorax. Scutum and scutellum mainly shining black, at most with weakly developed black-brown pollinosity. Devoid of pilosity except for tiny dark pile which are hardly visible, along anterior margin slightly longer; lateral margins dorsally of anepisternum with long black pile. Pleural sclerites (except meron, and anterior anepisternum) covered with long whitish or pale yellowish pile, black along dorsal part of posterior anepisternum.
Legs. Predominantly black to black-brown. Fore and mid leg with tibia silvery in basal third dorsally, ventrally less so; with short black pilosity, except in silvery part where pale. Hind leg ( Fig. 29 View FIGURES 29–36 ), silvery part on tibia restricted to dorsal side and for basal fifth to sixth; hind femur ventrally with few longer pale pile, poorly developed protuberance and tuft of dense black pilosity in apical fifth.
Wing ( Fig. 37 View FIGURES 37–48 ). Hyaline, sometimes slightly fumose. With narrow black-brown marking, consisting of microtrichia, along anterior margin from base to junction of vein R 4+5 with wing margin; extending posteriorly in basal half of wing for almost entire width, and with a marking covering crossvein r-m. Calypters black, except basal part where paler; with fringe of black pile.
Abdomen ( Fig. 61 View FIGURES 61–72 ). Mainly shining black; terga 2–4 partly with black-brown pollinosity except for bullae, lateral plates and narrowly along posterior margin. Tergum 2 with one medial bulla, and two slightly rugose lateral plates. Terga 3–4 with one medial and two lateral bullae. Dispersed pale yellow pilosity on terga 3–4; more densely but short pilosity along lateral margins of tergum 2. Sterna black to black-brown; with widely dispersed short pale and darkish pile. Male genitalia as in Fig. 85 View FIGURES 85–100 .
FEMALE. As male except for the following character states. Eye, facets of equal size; dichoptic. Frons ( Fig. 21 View FIGURES 21–28 ) black; with brownish pollinosity and short dispersed black pile dorsally, palish pile ventrally; medially near antennal insertion with small greyish fascia reaching eye margin; rugose area equal in height to 2–3 times length of ocellar triangle. Facial tubercle strongly pronounced.
Distribution. Burundi, Congo (DR), Kenya, South Africa, Uganda. Also reported from Tanzania [Kilimanjaro, by Speiser; see Bezzi (1915)].
Comments. The type specimen is labelled as ‘holotypus’ by Kassebeer in 1999, but has a separate label indicating this is a lectotype by Barkemeyer in 2002. The lectotype designation does not seem to have been published.
