Redescription, male. Dark brown, mostly gray tomentose, white setose. Length, body 9.3­ 11.0 mm; wing 7.3­8.2 mm. Head: Face with sparse setae; 2­4 pencil­like and 6­8 long, thin, brown bristles present; FHWR 1.0:4.6­1.0:5.5. Proboscis ventrally with narrow base yellow. Antenna mostly yellowish­brown, flagellum darker brown. Ocellar tubercle with 2 long, brown setae, and sparse, shorter white and brown setae. Occiput dorsally with 3­4 thin, brown, postocular bristles; apex of longest about half distance toward ocellar tubercle.

Thorax: Mesonotum sparse tomentose; wide, brown, median stripe and 2 lateral spots present, yellow to yellowish­gray tomentose laterally and posteriorly; sparse, mostly brown, short setae present; 3­4 dorsocentral and 4 lateral brown bristles present. Scutellum yellowish­gray tomentose, sparse yellow setose; 2 brown marginal bristles present. Pleuron mostly brown, meron sometimes partly, metapleuron usually narrowly yellow posteriorly; metacoxa yellow; tomentum gray, white setose; 3­6 brown, katatergal bristles present. Halter yellow.

Wing ( Fig. 5 View FIGURES 1­10 ): Dense microtrichose apically and along posterior margin narrowly. Cell r 4 with vein R 4 slightly concave apically, R 5 convex medially. Apex of cell m 3 oblique, pointed, near r­m.

Leg: Fore and hind coxae entirely yellow, gray tomentose, with thin, usually pale vestiture; middle coxae usually mostly brown, yellow or yellowish­brown apically, long brown setae often present. Trochanters yellow. Fore and middle femora mostly yellow, narrow brown band present at apical fourth to third; hind femur with band on about half or less, apex always yellow, rarely hind femur mostly brown. Femora ventrally with only long setae, usually yellow, sometimes mixed brown and yellow setae, rarely entirely brown setae below middle femur. Middle and hind legs anteriorly with unusually long, brown bristles, longest third to half as long as tibia or femur; HFWLR 1.0:5.0­1.0:6.0. Tibiae mostly yellow, anteriorly brown, with abundant, short, pale yellow to white setae; fore and middle tibiae laterally with fringe of much longer setae, especially abundant on apical half. Hind tibia slightly capitate apically. Tarsi white to pale yellow setose; bristles brown except 1 yellow on fore and middle tarsi; basal tarsomere of fore and middle tarsi and all tarsomeres of hind tarsus mostly yellow dorsally, narrow apex of basal tarsomere and all tarsomeres brown ventrally.

Abdomen: Mostly thin gray tomentose, tomentum dense on the apical 3­4 segments, mostly white setose; tergites light brownish­gray tomentose medially with short, brown setae. Tergites 1­3 with narrow lateral margin yellow. Sternites 3­4 with numerous erect bristles, long pale yellow and much shorter brown, respectively; sternite 5 basally with 1­2 bristles.

Terminalia ( Figs. 94­98 View FIGURES 94­101 ): Epandrium 3 branched, each slender; median branch stylelike, apex forked; ventral branch shorter, apex capitate. Hypandrium truncate, apex with 2 rows of long, wavy bristles.

Female. Differs from male as follows. Length, body 7.1­11.3 mm; wing 6.8­9.2 mm. Head: Face with 6­10 black bristles; 1.0:5.4­1.0:6.7. Leg: Only short, thin bristles present, none unusually long. Middle coxa usually black setose apically. Femora sometimes with brown band incomplete posteriorly. Middle femur usually with only brown posteroventral setae. Hind femur with 4­5 long, thin anteroventral and posteroventral bristles; HFWLR 1.0:5.0­1.0:7.0. Fore and middle tibiae with narrow apex and small brown spot present, fringe absent. Hind tibia with apical third brown to yellowish­brown. Tarsi with sparse white setae dorsally, sometimes absent on hind tibia and hind tarsus. Abdomen: Usually dark brown, sometimes basal 2­4 tergites narrowly yellow laterally; tergites dorsally brown tomentose with narrow apices and sides gray, gray tomentum of apical tergites thin, not dense as in males; sternites without unusually thick, long bristles or setae. Tergite 9 narrow medially, deeply emarginate anteriorly, side much longer. Terminalia ( Figs. 99­ 101 View FIGURES 94­101 ). Three spermathecae present, narrow, apex pointed. Sternite 8 broadly triangular apically.

Distribution. Captured in sandy coastal and estuary forests from November to March in Mozambique and South Africa.

Remarks. The wide face, unusually long bristles of the middle and hind legs, yellow fore and hind coxa further characterize O. cingulatus   . The fringed fore and middle tibia, abundant erect bristles on sternites 3­4, and only 2 thin, short, lateral bristles on sternite 5 further characterize the male. The black bristly setae along the apical margin of the middle coxa further characterize the female.

The holotype is in good condition.
