Campylocera laticeps ( Hendel, 1908) , comb. n. ( fig. 23 )

Diasteneura laticeps Hendel, 1908: 150 ; Hendel, 1909: 24, fig. 20 , 21 ; Enderlein, 1942: 100; Steyskal, 1980: 558.

M a t e r i a l. Type. Holotype Ơ Diasteneura laticeps : South Africa: “ Bothaville, Oranje Dr. Brauns /// 22. II. 90”, “ Diasteneura / laticeps Hend. / Type”, “Type” [dark red, shiny label] ( NHMW).

D i a g n o s i s. C. laticeps belongs in a group of species characterized by the partly black head, thorax, and usually also abdomen or legs, dark patterned wing ( fig. 23 , 1 ; 24 , 2 ) and more or less conspicuously developed ocellar triangle with 2–4 ocellar setae and antenna with long pedicel and flagellomere 1.

Within this group, about six described and undescribed species differing by the very high gena (0.5–0.7× as high as eye), large shining brown ocellar triangle 0.3–0.5 as long as frons width ( fig. 23 , 6 ), non-spinulose mid and hind coxae (in both sexes), very large, nonseparated cerci and extremely narrow medial surstylus (in male — as on fig. 24 , 3 ) and short (as long as abdominal tergites combined), wide conical oviscape (as on fig. 24 , 1 ) bearing around apical aperture one moderately long dorsomedial lobe, paired sensillar brushes (rows of 3–4 closely located thick setulae) and short latero-ventral lobes form a subgroup that corresponds to the genus Diasteneura ; the species differ mostly by the coloration of body and wings, and vestiture of scutellum and legs. C. laticeps differs from them all by the occiput entirely yellow (partly or entirely black in other species).

R e m a r k. Species assigned to Diasteneura form a well-defined, certainly monophyletic group supported at least by such synapomomorphies as high gena and large ocellar triangle, and possibly some sexually dimorphic characters, which are known only for some species of this subgroup (only one species is known from both species by far). None of the characters contradict their placement into Campylocera , and I therefore synonymize the latter name and Diasteneura Hendel, 1908 syn. n. The species formerly assigned to Diasteneura are transferred: Campylocera basilewskyi ( Vanschuytbroeck, 1963) , comb. n., Campylocera laticeps ( Hendel, 1908) , comb. n., Campylocera obscura ( Vanschuytbroeck, 1963) , comb. n., Campylocera similis (Steyskal, 1963) , comb. n., Campylocera variceps (Curran, 1928) , comb. n. In addition, new species recognized in collections must be described and new synonyms of nominal species established elsewhere (Korneyev, in prep.).
