Description. Male ( Fig. 36 ). Body length 6.5–7.5 mm. Head with frontal triangle, fronto-orbital plates, face, parafacials and gena with an intense whitish pollinosity ( Fig. 37 ); occiput grey. Frontal triangle slightly widened with slightly convex margins. Fronto-orbital plates with 3–4 long inclinate setae and with 8–9 setulae in outer row; parafacials wide, with 9–10 hairs along its length. Antennae black, short, postpedicel falling of mouth margin by 1.5 its own length. Aristal hairs shorter than half width of antenna. Vibrissae strong. Palpi yellow with outer surface with dense silver pollinosity.

Thorax evenly grey dusted. dc 2+3, all strong; meron bare; anepimeron with about 15 setulae. Wings clear, calypters white, halters brown. Legs dark, densely grey dusted, with reddish knees. The ventral spines on femora characteristic for the L. caesia group are absent. t1 with long submedian pv seta. f2 with about 10 fine v setae in basal half and 2 p preapical. t2 with a long pv below middle. Hind coxa with seta on posterior margin. f3 with 4–6 strong av at apical half and 8–9 fine long pv setae at basal 2/3. t3 with 1 long and strong median ad and with 4–5 av and 7–8 fine pv at apical half. Hind tarsus modified, tar3-1 with two approximated, short and strong v spines near base ( Fig. 38 ).

Abdomen evenly whitish-grey dusted, only tergite 3 with a pair of indistinct dark spots. Cercal plate with elongated and pointed apical part and with a pair of lateral processes.

Female differs from male as follows: body length 7–8 mm. Ventral spines distinct on f1 and f2. t 2 in 50% females with ad seta on one tibia, the rest 50% without ad. f3 with 2 av and 2–3 pv. t3 apart from ad with 2–3 av seta in apical third, these much stronger than in male. Hind tarsus unmodified.

Etymology. The name refers to the French word Polonaise meaning a Polish in the feminine gender. Named in honour of my Polish colleagues from Nicolaus Copernicus University, Torun: Andrzej Grzywacz, Marcin Piwszynski and Krzysztof Szpila. They visited Bird Sanctuary near Walvis-Bay two weeks before me and first collected this species.

Habitat. Specimens were found in the area of Bird Sanctuary. It is a nice ( Fig. 39 ) but quite artificial landscape—sewage fields of Walvis-Bay town. Due to strong evaporation in the Namib desert, the waters of the sanctuary lakes are salty, as is the soil around them. What the natural habitat of L. polonaise sp. nov. remains unknown.
