Pampsilota luederitzensis Koch, 2006

Pampsilota luederitzensis Koch, 2006b: 224. Described: female [holotype], male [1 paratype]. Type locality: Namibia, Lüderitz, Scorpion Hill.

Female.

Figures 21-24

Head black, including antenna. Thorax black. Legs black; tibiae whitish, apically slightly brownish, tarsi brownish. Wings hyaline with intercostal area slightly flavescent-hyaline; substigmal spot very small and slightly infuscate; costa light brown with basal half white, stigma, subcosta and rest of venation light brown. Abdomen yellowish brown; terga 1,2 black, terga 3-5 with small light brown median spot, tergum 5 additionally with light brown posterior margin, terga 6/7 brown; ventral surface of abdomen brown with yellow longitudinal median stripe.

Head parallel-sided behind eyes. Antenna 1.6 × as long as maximum head width; flagellum scarcely enlarged towards apex, quadrangular in cross section, somewhat flattened towards apex, ventral surface with moderately compressed longitudinal carina, other longitudinal carinae more weakly compressed. Eyes slightly converging towards clypeus. Anterior margin of clypeus shallowly, circularly emarginated; supraclypeal area roundly protruding up to ventral limit of interantennal carinae; interantennal carinae sharply ridged between antennae, converging below, extending about one third of way to clypeus. Vertex, frons, gena, clypeus and supraclypeal area sparsely micropunctate, shiny; pubescence whitish. Mesoscutum nearly impunctate, shiny; pubescence similar to that on head; lateral lobe of mesoscutum with narrow glabrous stripe. Valvulae 3: Figs 21 , 22 . Lancet with about 13 serrulae: Figs 23 , 24 .

Length: 6.0 mm.

Male.

Figures 25 , 62-63

General coloration similar to that of female. Head and mesoscutum with slight metallic lustre; anterior margin of labrum brownish. Tarsi light brown. Costa almost entirely whitish. Abdomen blackish, tergum 3 yellowish with light brown median spot, terga 4/7 light brown, distal terga yellow; sterna 7/9 yellow.

Antenna 1.7 × as long as maximum head width; apex of flagellum flattened, interior surface with sharply compressed longitudinal carina. Other characters as for female. Penis valve: Fig. 25 .

Length: 5.3 mm.

Type material examined.

Holotype: ♀. Labels: "Namibia, Lüderitz, Scorpion Hill, 27°49 ’S/16°36’, 09.-12.VIII.1997, Malaise trap, Marais’s & Kirk-Spriggs"; "Holotypus, Pampsilota luederitzensis sp. n. ♀, det.: F. Koch, 2005" (red) (NNIC).

Paratype: 1 ♂: Namibia: Lüderitz Distr[ict], 10 km NW Rosh Pinah, 27°54'S / 16°42E, 13.VIII.1990, C. Roberts & E. Marais (MFN).

Distribution.

Namibia (Fig. 37 ).

Diagnosis.

Pampsilota luederitzensis resembles Pampsilota brandbergensis in the body length not exceeding 6.0 mm (in other species at least 7.0 mm). The yellow pronotum and entirely black legs of the latter distinguish it immediately from Pampsilota luederitzensis with dark pronotum and largely pale tibia.
