Figs 4, 54–57, 77  
 Holopogon vumba Oldroyd, 1974: 47 (in key); 1980: 362 (catalogue). Type locality: Zimbabwe.   
 Afroholopogon vumba: Londt 1994: 63, figs 1, 2 head, 3 wing, 4 metathoracic leg, 23–25 ơ genitalia.   
Redescription: Based on holotype.  
 Head:Antenna: Dark red-brown (tip of style and sensillum orange), fine silver pruinose, black setose; segmental formula 1.0:1.1:3.4:0.4:1.8. Face black, entirely silver-gold pruinose, mystax black, extending almost to antennal sockets. Face width:head width ratio 1.0:4.2. Frons and vertex black, extensively shiny apruinose but red-gold pruinose frons, black setose. Occiput black, silver pruinose, white setose. Proboscis red-brown, white setose. Palpi: plp 1 orange with white setae, plp 2 brown with dark red-brown setae.   
 Thorax: Mesonotum black, postpronotal and postalar lobes orange-brown, extensively shiny apruinose except for silver-gold parts as follows – lateral margin, anterior area adjacent to postpronotal lobe, and posterior area extending from margin anteriorly to just posterior of transverse suture. Setation: ac – fine red-brown; dc – fine red-brown; npl – 2 short black; sa – 1 thin long black; pa – few fine black. Scutellum black, largely shiny apruinose except for silver-gold anterior margin, disc asetose, margin with approx. 7 fine long black setae. Pleura predominantly orange-brown but with red-brown parts, gold-silver pruinose except for apruinose area on katepisternum, sparsely white setose. Wing (Fig. 4) 6.7 x 2.2 mm, transparent with slight yellow staining, microtrichia redbrown, covering entire membrane, basal angle of r 4 17°. Halter brown with pale yellow knob. Legs: cx brown with yellow patches, silver pruinose except for some shiny bare areas, white setose (few black on anterior of cx 1); trochanters brown and orange; fem brown-orange (fem 1) brown-orange dorsally dark red-brown ventrally (fem 2) dark red-brown with orange-brown ends and dorsal strip (fem 3), white setose; tib orangebrown (tib 1–2) red-brown with orange-brown dorsally, macrosetae mostly black (a few white), setae white (a few dark red-brown); tar orange-brown, black setose.   
 Abdomen: Terga dark red-brown (T1–6) distal segments orange-brown, shiny apruinose except for silver distolateral parts, small black setae (white laterally). Sterna orangebrown, silver pruinose except for tiny shiny apruinose spots, fine white setose. Genitalia: ơ holotype not dissected and macerated, topotypic paratype ơ illustrated (Figs 54–57): Hypopygium unrotated; epand (in dorsal view) deeply incised forming two distally pointed lobes; goncx externally distally unilobed and projecting (in lateral view) beyond levels attained by epand and hypd; hypd (in lateral view), short, rapidly tapering (in ventral view) in two stages to elongate medial process.   
Variation: Individual variation minimal, although the paratype lacking an abdomen is somewhat smaller and lacks the extensive orange pleural areas seen in other specimens.  
 Type specimens (seen): ZIMBABWE: ơ holotype, 3ơ 1^ 1? paratypes, ‘ 6,000 ft / N. Vumba, [1953S 3122E] / S. Rhodesia / 8.4.1965 / D. Cookson.’, ‘ Holopogon / vumba sp.n. / det. H. Oldroyd 1973 / Holotype’ [paratypes have appropriate labels].   
Distribution (Table 1), phenology (Table 2) and biology: Known only from the type locality in the eastern highlands of Zimbabwe (Fig. 77), and only collected during April.  
 Similar species: A. meilloni (see discussion).
