Figs 30 , 60 , 144–146 Etymology: From Greek zophos (West). A species limited to the western part of South Africa . Description: Male (based on holotype . Condition: Excellent; left antenna entirely missing; terminal tarsomere of left metathoracic leg missing.). Head : Dark red-brown to blackish, silver-gold pruinose, shiny yellow setose. Antenna ( Fig. 30 ): Scape and pedicel orange, yellow setose, postpedicel orange proximally becoming brown-orange distally, terminal stylus ‘segment’ present, tipped with pit-enclosed spine-like sensory element. Segmental ratios: 1:0.4:3.4:0.3. Face dark red-brown, strongly silver-gold pruinose except on lateral parts of epistomal margin and a small spot below antennal sockets, mystax shiny yellow occupying ventral ½ of face. Frons and vertex blackish, fine silver-gold pruinose, yellow setose; ocellar tubercle anteriorly apruinose, fine pale yellow setose (no macrosetae). Occiput blackish, uniformly gold-silver pruinose, yellow setose. Palpus red-brown, yellow setose, terminal palpomere swollen, apex projecting with terminal sensory pit. Proboscis orange-brown, yellow setose. Thorax : Blackish with orange areas dorsally, silver pruinose, yellow setose. Prothorax entirely black, fine silver pruinose, yellow setose. Mesonotum blackish except for orange postpronotal and postalar lobes (and immediate surrounds), fine silver-grey pruinose, fine pale yellow setose. Mesonotal macrosetae (yellow when present): dc yellow confined to few pairs posterior to transverse suture, 2 npl , 1 spal , 3 pal . Scutellum entirely orange, fine silver pruinose, disc apparently asetose, hind margin with 4 yellow macrosetae. Pleura entirely blackish, silver pruinose, setae yellowish confined to anepst , kepst and ktg . Anatg and mes pnot black, contrasting with orange scutellum. Legs: cx black, silver pruinose, pale yellow setose; tro red-brown; fem , tib and tar uniformly orange, entirely yellow setose, claws dark red-brown with orange proximal parts. Wings ( Fig. 60 ): 10.3× 3.5 mm . Veins orange anteriorly pale brown posteriorly. Membrane extensively microtrichose (some proximal cells partly bare), distal cells pale brownish (from about first fork of Rs), proximal cells mostly transparent. Haltere yellow-brown. Abdomen : Extensively dark red-brown to blackish with large orange patches, dull pruinose, pale yellow setose. T1 blackish, T2–4 blackish with large orange patches posterolaterally, T5–7 similar to T4 but dissected with genitalia. Sternites similar to tergites but orange areas predominate posteriorly. Genitalia ( Figs 144–146 ): Epand bifid, forming pair of relatively long, fairly slender, undulating lobes that project beyond other genital structures. Lobes closely abut proximally, lying almost parallel with one another, slightly undulating (in dorsal view), with distal tips slightly inwardly directed. Proct simple, dorsally situated cerc appearing fused proximally. Goncx well developed, outer lobe projecting posteriorly to narrowly rounded distal end; dorsal finger-like process well developed, fairly short and stout; inner lobe well developed, long, distal end well sclerotised and medially directed. Gonst laterally compressed, dorsally directed, distal end curved anteriorly. Hypd moderately developed, less than half as long as broad, elongate oval with undulating, medially indented posterior margin. Aed triangular in ventral view with tiny bifid distal tip. Holotype : ♂ SOUTH AFRICA : ‘ Klip Vlei [ 30°59'S : 17°51'E ], Garies / Namaqualand’ ~ ‘ Museum Staff / Nov. 1931 ’ ( SAMC ). Distribution, phenology and biology: Known only from South Africa ( Table 1 ). The unique holotype was collected in November (Table 2). The biology is unknown. The type locality falls within the Succulent Karoo biome. Similar species: A member of the reynaudii species-group with close similarities to fulvicollis , reynaudii and tricolor .
