Trichardis turneri: Oldroyd 1974: 120 View in CoL ; 1980: 356 (catalogue).

Redescription (based on paratype ơ from type locality in excellent condition):

Head: Dark red-brown except for outer borders of face which are brown-orange, extensively silver pruinose (weak on face centrally), white setose. Antenna brown-orange, postpedicel red-brown with brown-orange base, setae orange and black; postpedicel not markedly clavate (L:D=3.2:1). Mystax white. Ocellar tubercle with 2 macrosetae. Proboscis dark red-brown, palpi red-brown.

Thorax: Brown-orange with dark red-brown areas, extensively silver pruinose, yellow and white setose. Postpronotum entirely pruinose, mesonotum dark red-brown with brown-orange borders, apruinose except for lateral and posterior margins, macrosetae pale yellow, setulae white. Scutellum apruinose except for narrow anterior margin. Anepisternum with pale yellow posterior macroseta, extensively pruinose except for a small anteroventral area. Proepimeron pruinose but weakly posteriorly, katepisternum pruinose but weakly anteriorly, anepisternum entirely pruinose. Legs: Brown-orange, femora orange-brown, pulvilli and empodium of similar length. Hind femur orange-brown, length:height ratio 3.3:1, ventral tubercles well-developed. Hind tibia lacking ventrodistal spur. Wing: 5.2× 2.2 mm. Costal vein strongly developed as far as wing tip, then very weakly developed along posterior margin of wing and absent from alula. Membrane extensively microtrichose but microtrichiae absent from parts of proximally situated cells; discal and r 5 cells entirely microtrichose.

Abdomen: Dark red-brown, apruinose, macrosetae pale yellow setulae white. T2 dark red-brown, apruinose.

ơ genitalia ( Figs 51, 52 View Figs 47–52 ): Epandrium in lateral view slightly longer than basal part of gonocoxite (i.e. excluding distal projection of gonocoxite and gonostylus). Proctiger moderately dorsoventrally compressed. Hypandrium greatly reduced and simple. Gonocoxite in ventral view without projections and with about 13 distally arranged macrosetae; mediodistal projection stout, with upturned sclerotised tip. Gonostyli stout, converging distally and ending in upturned slightly curved tips.Aedeagal prongs small, fairly straight.

Distribution and biology: A South African endemic restricted to the central parts of the country ( Fig. 58 View Fig 58 ). Adults recorded in summer between October and February (Table 1). The species has been collected on sandy ground in Acacia scrubland and in the vicinity of a stream. The biology is otherwise unknown.

Similar species: T. turneri has an entirely pruinose postpronotal lobe and in this respect can be grouped with apicalis , grisescens , ornata , picta , terminalis , testacea and zinidi . The species is distinctive, especially with respect to male genital form.
