Afropyrgota uzungwa V. Korneyev , sp. n. ( fig. 7 , 8 )

M a t e r i a l. 1. Type. Holotype ♀: Tanzania: Uzungwa Mts. , Chita Forest Reserve , 1500 m, 10.11.1994 (M. Stoltze & G. Petersen) ( ZMUC). Paratype: 1 ♀, labels as in holotype (dissected) ( SIZK).

D i a g n o s i s. This species can be recognized from the combination of its very large size (wing length> 15 mm), reddish brown body, yellow wing, and partly microtrichose parafacialium and mesonotal scutum; face with pair of black spots ventrally, without carina; frontal vitta orange, sparsely whitish microtrichose; ocellar setae present; palp reddish yellow, cigar-like, 3 times as long as wide, short setulose along most of its length; scutum reddish brown with brown, sparsely white microtrichose medial area, densely and moderately long black or brown setulose; scutellum with three or four long black setae on each side, almost as long as scutellum length; wing very long, 16.5–17.2 mm long, mostly yellow, brownish along veins; mid femur without femoral organ; abdominal sternites with long black setae; oviscape brown, slightly longer than syntergite 1+2, conspicuously compressed dorso-ventrally.

D e s c r i p t i o n. Head ( fig. 7 , 2 , 3 ) brown to orange, frontal vitta brownish red or orange, matt, very sparsely whitish microtrichose at middle, with 20–25 moderately long black mesofrontal setulae in its anterior half and 1 pair of black proclinate orbital setae, c. 1.0– 1.1 times as long as wide in posterior half; parafacial 1.7 times as wide as flagellomere 1, opalescent or sparsely whitish tomentose in its dorsal portion (at level of antenna base); eye 1.6 times as high as wide, 1.8 times as wide as parafacial and 2,75 times as high as gena. Face matt, brownish yellow, with two shining black spots lateroventrally, concave, with very low medial carina. Occiput entirely brown. Antennae brown, first flagellomere 2.5 times as long as wide, 1.2 times as long as pedicel and 2.5 times as long as scape. Arista entirely whitish yellow, 2-segmented. Scape 1.2–1.3 times as long as wide. Palp reddish brown, 3 times as long as wide, and as long as first flagellomere, moderately densely setulose over its medial and lateral sides in apical half. Labellum very large, almost as long as eye height. Ocellar seta present, almost half as long as flagellomere 1 and 0.6 times as long as medial vertical seta. Lateral vertical setae (vte) well developed, 1.3–1.5 times as long as postocular setulae; medial vertical setae (vti) 0.75 times as long as pedicel and 1.4–1.6 times as long as postocellar, ocellar and orbital setae and 1.5 times as long as mesofrontal setulae (above lunule).

Thorax reddish brown. Prosternum saddle-like, short setulose. Postpronotal lobe with 10–15 long thinner black setulae and 2–3 long seta; proepisternum with 8–12 setae. Scutum 1.2 times as long as wide, reddish brown with darker brown areas lateral of dorsocentral setae, moderately long and densely black setulose, white pollinose, with microtrichia not obscuring underlying cuticle; 2 (–3) notopleural, 1 supra-alar, 1 intra-alar, 1 postalar, 2 postsutural dorsocentral, and 0 acrostichal setae. Scutellum reddish brown, whitish microtrichose, with 3–4 black setae at each side 0.7–0.9 times as long as scutellum, without setulae ( fig. 7 , 4 ). Anepisternum reddish brown to yellow, densely black setulose; posterior part with 2–3 long setae and 25– 30 setulae of various length; anepimeron with 3–4 long black setae and 4–5 slightly shorter setulae; katepisternum with 1–2 long black setae and 12–17 setulae posterodorsally. Katatergite, anatergite and mediotergite reddish brown, subshining or matt, sparsely whitish microtrichose.

Wing ( fig. 7 , 5 ) entirely yellow, brownish along veins, with narrow hyaline areas in basal cells. Wing length 16.5–17.2 mm. Lower calypter narrow, without cilia; upper calypter with moderately long (half as long as calypter width) brown or black fringe but without conspicuously thicker black cilia. Halter yellowish.

Legs ( fig. 7, 6–8 ) entirely reddish, black setulose and setose, except tarsi golden brown setulose. Coxae moderately long, sparsely setose and setulose, unmodified. Fore femur ( fig. 6, 6 ) basally sonewhat thickened, spindle-like, moderately long setose on posterior surface. Mid femur ( fig. 7, 7 ) on anterior surface densely black setulose, without femoral organ. Hind femur moderately narrow, short setulose without long setae (except basiventral seta) ( fig. 7 , 8 ).

Abdomen moderately wide and robust, 1.5 times as long as thorax, with densely black setose and setulose tergites and sternites, with syntergite 1+2 long, 1.4–1.5 times as long as tergites 3–6 combined ( fig. 8 , 1 ). Synsternite 1+2 short Y-shaped ( fig. 9 , 3 ). Sternites 3– 6 subquadrate, with 2–3 black setae and 7–9 setulae at posterolateral corners ( fig. 9 , 3 ).

Female genitalia. Oviscape ( fig. 8 , 1–3 ) black, densely black setulose, dorsoventrally compressed, as long as or slightly wider than long, and as long as tergites 3–6 combined, with apex bent ventrally, bearing no hooks, only setulae on lateroventral lobes ( fig. 8 , 4 ), and medioventral desclerotized area ( fig. 8 , 4 ) as in A. copelandi sp. n. Eversible membrane without sclerotized lobes or raspers. Oviscape ( fig. 8 , 5 ) wide, robust. Spermathecae sausage-like, poorly sclerotized ( fig. 8 , 6 ).

Male unknown.
