Figure 5A− D Diagnosis. Ismarus kakamegensis sp. n. is similar to I. clarkae Masner, 1976 from the Nearctic region. It differs mainly in the antenna colour, A1/A3/A4 ratio and metasomal sutures: in I. clarkae antenna yellow with whitish ventral side of scape, A1 much longer than A3 and A4, metasoma after T2 mostly obsolete or incomplete; in I. kakamegensis sp. n. antenna brown with yellow scape and pedicel, A1 almost equal length to A3 and A4, metasoma after T2 with 4 distinct sutures.

Figure 5. Ismarus kakamegensis sp. n., female. A Mesosoma in lateral view B Head in dorsal view C Habitus in lateral view D 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 present with 3 small pits on anterior margin (Fig. 5D); humeral sulcus deep and long, longer than length of tegula (5:4); scutellum smooth and slightly convex, posterior rim rounded (Fig. 5D); anterior scutellar pit large and deep, much shorter than remaining scutellar disc, distinctly crenulate at bottom, median keel absent (Fig. 5D); mesopleuron smooth with deep crenulate line along posterior margin (Fig. 5A); metapleuron rugose and covered with dense whitish long setae. Wings. Radial cell completely closed, 1.6 x as long as wide and 0.55 x as long as marginal vein (Fig. 5C). Legs. Fore and mid legs slender; hind tibiae incrassate posteriorly, its maximum width slightly wider than hind femora (11:9). Metasoma.

Colour. Body yellow except face whitish-yellow, mesoscutum and scutellum blackish, dorsal part of petiole and basal part of T1 darkened; antennae brown except scape and pedicel yellow, tegulae and legs uniformly yellow; wings hyaline, covered with brown setae.
