Material examined: NAMIBIA: Walvis Bay env., 22.97 ° S 14.54 ° E, 5–9 December 2018, N. Vikhrev, 16♂, 26♀; Luderitz env., 26.61 ° S 15.19 ° E, sewage fields, 20–22 January 2021, N. Vikhrev, 2♀ (all ZMUM) .

Distribution. Reliably known from South Africa and Namibia. For the collecting site in Namibia see the notes on the type locality of L. polonaise sp. nov.

REDESCRIPTION. Male. Body size — 5.5– 6 mm. Head. Frontal triangle shining black, interfrontalia matte black, fronto-orbital plate shining black but grey dusted in anterior half; parafacials and face whitish-grey, occiput grey. Antennae black. Arista in basal half with hairs 0.5x as long as width of antenna, in apical half bare. Vibrissae strong. Palpi covered with dark grey pollinosity, yellowish on margins. Thorax black, scutum shining, pleura grey dusted. dc 2+3 all strong; anepimeron with about 12 setulae; meron above hind coxa with 4–5 hairs; katepimeron with 2(3) hairs in posterior half; scutellum bare on ventral surface. Wings brownish-hyaline, calypters whitish-yellow, halter yellow. Legs with coxa, trochanters and femora black; tibiae and tarsi yellow (mid and hind tarsi dorsally darkened). t1 without seta. t2 with 1 p and in some specimens with additional seta on p, pv or v position; hind coxa bare; f3 at apex with 1 av and 1–2 pv, otherwise bare; t3 with 1 ad; tarsi unmodified. Abdomen with colour pattern similar to that of L. nana ( Figs 17, 18): tergites 3 and 4 mainly black with three whitish spots, a pair of antero-lateral ones and rounded postero-median one. Tergite 5 with a pair of large rounded anterolateral spots. Abdominal tergite 3 without a pair of small rounded knob-like process at each ventral fore-marginal corner (characteristic for L. nana ). Sternite 5 with strong medial process clearly visible on intact abdomen. Cercal plate and sternite 5 as shown in Fig. 21.

Female differs as follows. Body size 5.7– 6.5 mm. Tarsi darkened. Scutum with the median pruinose patch at level of 2 nd and 3 rd post dc, typical for females L. tentaculata and L. draperi . Normally 2+3 dc, but some specimens have additional weak pair between 1 st and 2 nd post dc and may be described as dc 2+4. Abdominal pattern similar to that of the male but less contrasting black-white, more greyish ( Fig. 19).

Remarks. L. capensis was described from 6♂ and 6♀ from Cape Town, South Africa. The following characters from Zielke’s (1971b) description fit our Namibian series: 6–7 mm; palpi dark, femora dark, tibiae and tarsi yellow; t1 without seta; t2 with p; f3 at apex with 1 av and 2 pv; t3 with 1 ad; cercal plate as in Fig. 20. On the other hand, Zielke indicated 2+4 dc; did not mention the presence on the female scutum of the pruinose patch and drew unprecedented paired internal processes on sternite 5 ( Fig. 20). However, our Walvis Bay series has a very characteristic medial process on male sternite 5, it looks very similar to those on Zielke’s drawing, and I believe that duplication of the process has been a result of some funny error. Note also the remarks below to L. aurocochlearia Seguy, 1950 , probably L. capensis is not the oldest name for the taxon. Vikhrev (2014) supposed a close relationship between L. nana and L. tentaculata group, the intermediate characters of L. capensis support this hypothesis.
