( Figs 4G–K ) Diagnosis: Surstyli subsymmetrical, broad in lateral view; cerci elongated; ST8 large, with circular m.a.; OG round, IG slightly pointed; phallic guide with two apical projections in ventral view; tubes of the phallus very short; closest relative is Claraeola sicilis Skevington, 2002 . Type material: Malawi : 1♂ , PT, SE1134AD, 5km E. of Mzuzu , 6.iii.1987 , J&A Londt , Roadside woodland with very long grass ( NMSA ) . South Africa : 1♂ , HT, Enon Farm , Richmond , Natal, S . Africa, B. & P. Stuckenberg, Jan 1964 ( NMSA ) . Male Head . Third antennal segment obtuse; dark brown. Face silvery pollinose. Frons, upper part subshining black, lower part black pollinose except drop-shaped shining spot in the middle; eyes touching for distance equal to 4-5 times ocellar triangle. Occiput, lower half silvery pollinose, upper half subshining black. Thorax . Humeri dark brown. Mesonotum (viewed obliquely from front) brownish pollinose; subshining black from the side. Scutellum brownish pollinose, with 7–9 pale hairs. Dorsocentral hairs weakly developed. Halter dark brown. FIGURE 4. Male genitalia of Claraeola nigripennis (A–F) and Cla. stuckenbergi sp. nov. (G–K).—A: outer surstylus with phallic guide, lateral view, B: dorsal view, C: inner surstylus, lateral view, D: sperm pump with ejaculatory apodeme, E: surstyli, dorsal view, F: ventral view with phallic guide, phallus (without ST8), G: outer surstylus with phallic guide and outer gonopod, lateral view, H: dorsal view, I: inner surstylus, lateral view, J: surstyli, dorsal view, K: ventral view with phallic guide, phallus (without ST8). Scale bars: 0.1 mm Legs. Entirely black (hind femora shining pv). Ventroapical row of spines on femora missing. Subapical (distal) spines on first four tibiae missing. No anteromedial hairs on 3rd tibia. Hind trochanter with 4–6 short whitish hairs on ventral side. Pulvilli distinctly shorter than last tarsal segment. Wing. Fourth costal section 0.3–0.4 times as long as third costal section. Cross-vein R-M beyond 2/5 of discal cell. Cross-vein M-M concave. Pterostigma fully coloured. Hairs on tegula uncertain. Abdomen . Viewed obliquely from front tergites entirely subshining black with stripes. Hairs dispersed, pale and long (as long as width of tibia at widest). Laterally spines on first tergite missing only hairs are present as on T2 and T3. Postabdomen in dorsal view: T5 2.2–2.3 times as long as ST8. Genitalia without dissection: ST8 brownish pollinose, with round m.a., occupying 2/3 of width of ST8, SS and EP dark brown, SS perpendicular to body on ventral side. Genitalia. Surstyli subsymmetrical, broad in lateral view; epandrium with deep V-shaped form around elongated cerci; ST8 large, with circular m.a. ( Fig. 4H ). SES uncertain; gonopods very short, OG round, IG slightly pointed ( Fig. 4K ); phallic guide with two apical projections in ventral view, somewhat bent towards SS in lateral view( Fig. 4G ); phallus trifid, tubes very short, laterally hairy at base in ventral view. Female—Unknown. Remarks —Based on comparison with material identified by Skevington it is a very close relative of the species Claraeola sicilis Skevington, 2002 , which is only known from Australia . Distinguishing characters include: dorsal view of IS (thicker in C. sicilis ), lateral view of SS (rounded in C. sicilis ), IG in ventral view (shorter in C. sicilis ), hairs on the base of PG in ventral view (fewer in C. sicilis ), membraneous parts of PH (more extended in C. sicilis ). Distribution— Malawi , South Africa . Etymology —The name refers to one of the collectors, the late Brian Stuckenberg, who is remembered as the excellent dipterist from Pietermaritzburg who passed away in 2009.
