Campylocera nigripennis (Hendel, 1934) comb. n. (fig. 22)

Prohypotyphla nigripennis Hendel, 1934: 150; Vanschuytbroeck, 1963: 47; Steyskal, 1980: 559.

M a t e r i a l. Type. Holotype Ơ: Sierra Leone: “Sierra Leone / Njala / 7-X-30 / E. Hargreaves ”, “Prohypotyph- / la / nigripennis /H. / Ơ F. Hendel det.”, “Hendel / coll.” (NHMW).

D i a g n o s i s. C. nigripennis is similar to C. caudata and C. gracilis from the group of species represented by reddish-yellow, large flies with elongated pedicel and flagellomere 1 (latter parallel-sided, twice as long as wide and apically blunt), lacking outer vertical setae, moderately long body, setose mid and hind coxae, short preapical ventral setae on mid and hind femur, short setulose scutellum with 4 scutellar setae, easily differing from all known Campylocera by almost entirely dark brown wing (fig. 22, 10), winding vein R 2+3, facial carina wide and low, ocellar, postocellar, anterior notopleural and katepisternal setae lacking. Wing length 9.2 mm.

R e m a r k. Known from a unique male only, this species is believed to belong in the group of species, which includes C. loewi, C. caudata and related species, differing by the numerous autapomorphic characters (low facial carina, ocellar and anterior notopleural setae lacking, wing dark brown). Otherwise it fits the diagnosis of Campylocera in its essential characters, and I synonymize Lygiohypotyphla Enderlein, 1942 syn. n. with it.
