Figure 10. Ismarus nigrofasciatus sp. n., female. A Habitus in lateral view B Head in dorsal view C Mesosoma in dorsal view. Mesosoma. Pronotum in dorsal view punctate with whitish long setae; pronotal shoulders angled; lateral pronotum predominantly smooth and concave except lower margins punctate with whitish setae; mesoscutum smooth and convex; notauli weakly present with 6 very small pits on anterior margin (Fig. 10C); humeral sulcus deep and long, slightly longer than length of tegula (5:4); scutellum smooth and slightly convex, posterior rim rounded (Fig. 10C); anterior scutellar pit large and deep, much shorter than remaining scutellar disc, distinctly crenulate at bottom, median keel absent (Fig. 10C); mesopleuron smooth with deep crenulate line along posterior margin; metapleuron rugose and covered with dense whitish long setae. Wings. Radial cell completely closed, 1.75 x as long as wide and 0.7 x as long as marginal vein (Fig. 10A). Legs . Fore and mid legs slender; hind tibiae incrassate posteriorly, its maximum width slightly wider than hind femora (10:9). Metasoma. Petiole subquadrate (9:10), with irregular longitudinal carinae; tergites smooth, with scattered setigerous punctures; base of second tergite with several short costae basally and short median furrow, extending 0.20 x length of second tergite; suture between T2 and T3 obsolete, following sutures complete and deeply impressed. Colour. Body whitish-yellow to yellow except median longitudinal band of mesoscutum and scutellum blackish (Fig. 10C); antennae, tegulae and legs uniformly yellow; wings hyaline, covered with brown setae. Measurements. Head length 0.34 mm, width 0.61 mm; mesosoma length 0.67 mm, width 0.49 mm; metasoma length 1.12 mm; fore wing length 1.92 mm; body length 2.13 mm. Variation. Body length 1.97-2.13 mm. Radial cell closed, 0.65 -0.70x as long as marginal vein. Male. Unknown. Distribution. Malawi, Uganda. Etymology. The specific name is an adjective derived from the Latin words nigrum for black and fasciatus meaning with stripe or band.
