description: <i>Afropyrgota ota</i> V. Korneyev, sp. n. (fig. 6) M a t e r i a l. <b>1. Type.</b> Holotype &amp;female;: <b>Nigeria:</b> Oludu C. R. / SE State 27 Mar 1971 / Col. J. T. Medler (USNM). Paratype &amp;female;: <b>Burundi</b>: Ruvubu National Park, 1382 m, 2.98144° S, 30.45531° E, Malaise trap, near Ruvubu River, 22.04– 07.05.2010 (R. Copeland) (NMKE). D i a g n o s i s. This species is similar to <i>A. marshalli</i> in having two pairs of scutellar setae, and frontal vitta yellow, similar shape and length of oviscape, differing from it by having entirely reddish yellow setulose body, including pleura, abdomen and legs (pleura, abdomen and legs black setulose in <i>A. marshalli</i>) and mid femur with cuneiform femoral organ narrower than femur (entirely lacking in <i>A. marshalli</i>). D e s c r i p t i o n. Head (fig. 6, <i>2, 3</i>) yellow, frontal vitta yellow, c. 1.1 times as long as wide in posterior half; parafacial 1.73 times as wide as flagellomere 1; eye 2 times as high as wide, 1.3 times as wide as parafacial and 2.6 times as high as gena. Face concave, with low, but conspicuous medial carina, in holotype uniformly yellow, in paratype with 2 brown spots ventrally. Gena with dark brown vertical patch over subocular sclerite. Occiput entirely yellow. First flagellomere entirely orange yellow, 2.7–2.8 times as long as wide, 1.72 times as long as pedicel and 3 times as long as scape. Arista entirely reddish yellow, 2-segmented. Scape 2 times as long as wide. Palp yellow, cylindric, 4–4.5 times as long as wide, and c. 0.8 times as long as first flagellomere. Labellum very large, but shorter than eye height. Lateral vertical setae (vte) distinctive, 0.5–0.6 times as long as medial vertical seta; the latter (vti) as long as pedicel and 1.6–1.8 times as long as postocellar, ocellar and orbital setae and 2.5 times as long as mesofrontal setulae (above lunule). Thorax yellow to orange yellow, without dark pattern. Postpronotal lobe with 8– 10 setulae and one long seta; proepisternum with 7–9 setae; prosternum saddle-like (fig. 6, <i>7</i>). Scutum 1.1–1.2 times as long as wide, subshining yellow with orange areas at place of attachment of muscles, sparsely yellow setulose, with white microtrichia not obscuring underlying cuticle; orange to brown setose, 2 notopleural, 1 supra-alar, 1 intra-alar, 1 postalar, 1–2 postsutural dorsocentral, and 0 acrostichal setae. Scutellum yellow, inconspicuously whitish microtrichose, with one pair of apical setae 1.5 times as long as scutellum, but without setulae. Anepisternum yellow, in holotype uniformly yellow, in paratype with dark yellow or brownish anterior part; posterior part with 2–4 long setae and 10–12 irregular long setae; anepimeron with 2–3 long setae and 3–6 irregular long setae; katepisternum with 1– 3 long setae and 9–15 thinner and slightly shorter setulae posterodorsally. Katatergite, anatergite and mediotergite brownish yellow, subshining, very sparsely whitish microtrichose. Wing (fig. 6, <i>5</i>) pale yellowish along anterior margin and veins, covered with greyish microtrichia, with lighter areas between bm-cu and r-m and r-m and dm-cu; cell bm and alula mostly glossy, translucent, devoid of microtrichia. Vein R 4+5 bare. Wing length 10.5–14.0 mm. Lower calypter very narrow, without cilia; upper calypter with yellow fringe basally and 3– 4 yellow cilia half 0.4 times as long as calypter width. Halter creamy white, with brownish knob. Legs entirely yellow, brown setulose and brownish yellow setose. Coxae moderately long and sparsely setose and setulose, unmodified. Fore femur moderately narrow, long setose on posterior surface. Mid femur (fig. 6, <i>7</i>) on anterior surface setose in basal onequarter and with cuneiform femoral organ narrower than its width and much shorter than its half. Hind femur narrow, short setulose without long setae (except basiventral seta). Abdomen (fig. 6, <i>8</i>) narrow, cylindrical, almost twice as long as thorax, with syntergite 1+2 elongate, 1.2 times as long as tergites 3–6 combined. Sternites as in <i>A. marshalli</i>. Oviscape as in <i>A. marshalli</i>, entirely orange, short and sparsely black setulose, uncompressed, almost as high as wide and as long as tergites 3–6 combined, with apex short and slightly bent ventrally, bearing very short dorsomedial and two lateroventral lobes, but neither hooks, nor long setulae. Eversible membrane and aculeus not dissected. Male unknown.
