( Figs. 1B, J View FIGURE 1 , 2A, F View FIGURE 2 ) urn:lsid:zoobank.org:act: CF46D82C-E36E-423B-B687-0478A6083DBE

Material examined. Holotype Ƌ, slide mounted in Canada balsam by A. Harrison , NAMIBIA: Kunene, near Okandombo Guard Post, Cunene (sic) River , 17°02'00"S, 13°28'53"E (light trap, site #22), 27 xi 1998 (F. de Moor et al), coded as KUN GoogleMaps . 136B (AMGS).

Description. Male (n=1 lacking all tarsomeres, hypopygium part-laterally mounted).

B.l. 3.4 mm. W.l. 1.5 mm.

Head. Antenna Fl1–12 455, Fl13 404, A.R. 0.89. 21 clypeals, 7 aligned verticals. Palpomeres (2–5) 25, 115, 165, 185.

Thorax. Antepronotal lobes narrow and meeting beneath extended scutum ( Fig. 1B View FIGURE 1 ). Ac?, Dc?4 with 1 in humeral position; Pa 4, Scts 4.

Wing. Pattern as in Fig. 1B View FIGURE 1 with dark base. V.R. 1.24. Vein setation: R with 19, R1 with 18, R4+5 with 22 along full length of vein.

Legs with P1 femora dark with short median pale section, distally slightly dilate subapically, tibia pale with darkened apical 40%, P2 femora dark in distal half, tibia dark in basal half, P3 femora with short dark band in pale basal section, dark for apical 40%; all tarsomeres missing. Lengths: P1 780, 480, –; P2 760, 490, –; P3 850, 700, –. Foretibial spine 40, slender, gently curved outward, scale at base microtrichiose.

Genitalia ( Fig. 2A View FIGURE 2 ). TIX with cluster of 12 strong anal tergite setae just anterior to base of anal point; margin of TIX rounded (not squared off). Anal point appears parallel-sided, gently curved in lateral view, 64 long from origin on TIX. Superior volsella ( Fig. 2F View FIGURE 2 ) with base difficult to discern, probably with 1–2 dorsal setae; digitus 37 long, curved, of even width to broad point. Base of mv well developed (according to orientation), 20 long and wide, with 4 or 5 simple setae up to 15 long. Inferior volsella (lying directly beneath gonostylus), 85 long, slender, with 5–6 long setae on inner subapical margin. Gcx 96, gently rounded, Gst 120, broadening distally then tapered to blunt point.

Female, Pupa and Larva unknown.

Etymology. (Derivato nominis). The specific epithet recognises the Kunene, river and region, of north-western Namibia, where the solitary specimen was collected by light trapping by Ferdy de Moor and his team. To be treated as a noun in apposition. Dual authorship recognises the late Arthur Harrison's description of this new species in an unpublished manuscript, from a slide he made from sorting extensive Kunene material.
