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.
Type material
(1♀). Holotype, 1♀, KENYA: Kakamega District, Isecheno, Isecheno Nature Reserve, 0°24'N, 34°87'E, 21-28.II.2002 (MT), R. R. Snelling leg., CJDAF010080 (deposited in CNCI).
Description.
Holotype (Female). Head. Head in dorsal view much wider than long (5:3), wider than width of mesosoma (5:4) (Fig. 5 B–C); POL: 12; LOL: 7; OOL: 11 (Fig. 5B); ocelli large, LOL slightly longer than diameter of lateral ocellus (7:6); vertex behind ocelli nearly flat in lateral view; eye large and without setae; inner orbits, frons and temple with few sparse setae; above antennal sockets, face and cheek with few long setae; antenna long, as long as body length; scape and pedicel with scattered setae; A3-A15 with dense and short setae; antennal segments in following proportions (length:width): 11:4; 7:3; 10:2; 11:2; 8:2; 7:2; 7:2.5; 6:2.5; 6:2.5; 6:2.5; 6:2.5; 6:2.5; 6:2.5; 5:2.5; 9:2.5 (Fig. 5C).
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 × as long as wide and 0.55 × 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. Petiole subquadrate (10:11), with strong costae dorsally; tergites smooth, with scattered setigerous punctures; base of second tergite with several short costae basally and very short median furrow, 0.15 × length of second tergite; suture between T2 and T3 obsolete, following sutures complete and deeply impressed.
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.
Measurements. Head length 0.33 mm, width 0.55 mm; mesosoma length 0.61 mm, width 0.43 mm; metasoma length 0.82 mm; fore wing length 1.69 mm; body length 1.76 mm.
