Redescription: Based on holotype.  
 Head:Antenna: Black, gold pruinose except for apruinose scape, black setose; segmental formula 1.0:0.8:2.9:0.2:1.3. Face black, gold-silver pruinose (weak in region of mystax), mystax strong, black dorsally yellow ventrally and ventrolaterally, extending over threequarters of face (asetose just below antennae). Face width:head width ratio 1.0:4.4. Frons and vertex black, mostly shiny apruinose, dark red-brown to black setose, ocelli red. Occiput dark red-brown, silver pruinose, white setose (few short pale yellow setae dorsally). Proboscis and palpi dark red-brown to black, yellow setose.   
 Thorax: Mesonotum black, shiny apruinose except for the following silver-gold areas – lateral margin, fairly extensive area adjacent to postpronotal lobe, narrow strip anteriorly corresponding with position of acrostichal setae, broad posterior strip from posterior margin to just beyond transverse suture. Setation: ac – weak yellow anteriorly, longer postsuture; dc – long yellow; npl – 2–3 black (anteriorly) and yellow plus few minor setae; sa – 1–2 yellow plus many minor setae; pa – 2 yellow plus few minor setae. Scutellum black, largely shiny apruinose but weakly silver pruinose anterior and posterolateral margin, disc asetose, margin with 10 setae (7 black, 3 yellow). Pleura dark red-brown to black, almost entirely gold pruinose except for small apruinose areas on anepisternum, katepisternum and meron, sparsely yellow setose. Wing 5.3 x 2.3 mm, pale brown-yellow, microtrichia brown, covering almost entire membrane, basal angle of r 4 23°. Halter pale brown with yellow knob. Legs: cx dark red-brown, gold pruinose, yellow setose; trochanters dark red-brown; fem dark red-brown with red-brown distal tip, yellow setose (few black dorsodistally); tib orange, macrosetae black, setae yellow; tar red-brown, most setae black.   
 Abdomen: Terga black, shiny apruinose except for silver-gold lateral margins, setae dorsally small yellow longer laterally. Sterna dark red-brown, entirely dull gold pruinose, long fine yellow setose. Genitalia: Holotype not dissected and macerated, a specimen from Willowmore illustrated (Figs 20–22): Hypopygium rotated through about 180°; epand (in dorsal view) incised medially to form two moderately pointed lobes broadly joined basally; goncx externally distally bilobed, lobes of distinctive shape; hypd (in lateral view) elongate, projecting distally well beyond level attained by goncx, gradually tapering (in ventral view) to broadly clubbed medial process.   
 Variation:Sexes similar. Female genitalia illustrated (Figs 61, 62) for generic comparison with Ischiolobos. The species displays some variation. Many specimens are a little smaller than the holotype, setae are frequently white instead of yellow and pruinescence is silver rather than gold. The distribution and extent of mesonotal pruinescence shows variation which may be geographic.   
 Type specimens seen: SOUTH AFRICA: ơ holotype, 2^ paratypes (capensis), ‘Kapstadt [Cape Town 3355S 1825E] / 27.xi.-1.xii.1958 / Lindner leg.‘ ~ ’29.xi.’, ‘ Heteropogon / capensis Lind. / Lindner det.’, holotype is labelled ‘Typus / Lindner / 1961 [sideways] [red ink]’ and paratypes ‘ Paratypus / Lindner / 1961’ (SMNS). ơ holotype, 1^ paratype (tomentosus), ‘Elandsberg Mts South / of Cockscomb Peak / Patensie area / 1.12.67 3424DB [sic. 3324DB] / B&P Stuckenberg’.   
 Note: Lindner (1961) gives additional data for the capensis types, i.e. ‘(Kloof Neck – Lionhead)’, that does not appear on specimen labels.This information is likely to be correct as he personally collected the material. So I designate the type locality as Kloof Neck [3356S 1823E].

Distribution (Table 1), phenology (Table 2) and biology: Found mainly in the Fynbos and Succulent Karoo Biomes of the Western Cape (Fig. 78). The species flies from September to January and is frequently collected on rocky outcrops and large boulders.  
 Similar species: A. melas and africanus, but also peregrinus (see discussion).
