Campylocera angustipalpis ( Enderlein, 1942) ( fig. 14 )

Clemaxia angustipalpis Enderlein, 1942: 129 ; Vanschuytbroeck, 1963: 65; Steyskal, 1980: 558.

Campylocera (Clemaxia) angustipennis : Aczél, 1958: 40 (incorrect subsequent spelling).

M a t e r i a l. Type. Holotype ♀ Clemaxia angustipalpis : Togo: “[W-Afrika] Togo / Bismarckburg / 5.7. [18]93 L. Conradt S. ”, “ Clemaxia / angusti- / palpis Enderlein Dr. Enderlein det. 1934 | Type [pale red label]” ( MNKB).

D i a g n o s i s. This species can be recognized among other Campylocera species from the long pedicel and flagellomere 1 parallel-sided, apically bluntly rounded, fore femur with moderately long and thin setae, but without thickened apicoventral setae on dorsal surface, mid coxa with row of strong setae ( fig. 14 , 10 ) hind coxa antero-ventrally with somewhat thickened spinulose setulae ( fig. 14 , 10 ) not forming comb or thick brush; veins brown bordered, cell R 2+3 apically with narrow brown apical margin ( fig. 14 , 2 ), oviscape long and narrow, without peculiar modified structures ( fig. 14 , 1 , 13 ). Mesonotum without presutural supra-alar setae; scutellum short setulose, 2 setae on each side. Th is species is closely related to C. gracilis Hendel 1914 from Southern Nigeria differing mainly by longer setulose fore femur (short setulose with short, slightly thickened setulae apicoventrally in C. gracilis ). Study of additional material is necessary to clarify, if this is a reliable difference of species or individual variability. No reliable associations with males found in collections are available.

R e m a r k. Enderlein (1942) originally recognized Clemaxia as a genus to place the flies with incomplete costa, vein M reaching wing margin, R 2+3 with or without stump vein, and scutellum bearing 4 setae. In this paper, all the Old World Adapsiliina species with incomplete costa are lumped in a monophyletic genus Campylocera . I therefore synonymize both generic names. Within Campylocera , C. angustipalpis forms a small group of species together with C. loewi ( Hendel, 1908) , C. gracilis , and C. caudata ( Hendel, 1914) ; these species share elongate and narrow pedicel, elongate and blunt flagellomere 1, small or moderately developed ocellar triangle with 1–2 pairs of ocellar setae, mid and hind coxae of females with more or less thickened setae, and oviscape narrow and long, 1.3–2 times as long as abdominal tergites combined and no sclerotized lobes or long sensillar brushes or combs at its apical aperture. C. angustipalpis can be distinguished from superficially C. gracilis , which shares similarly setulose mid and hind coxae of females, by the long and fine setae of the ventral rows on fore femur (the basalmost seta twice as long as femur width), whereas in C. gracilis they are short and spurious (the basalmost seta at most as long as femur width).
