Thorax: Pronotum brown. Pleuron mostly yellow, anepisternum, katepisternite, anterior anepimeron, and meron at least brown. Katatergal bristles yellow.
Wing as O. comosus except apex of cell m 3 truncate ( Fig. 11 View FIGURES 1120 ).
Leg: Hind trochanter with 23 short brown bristles. Fore femur (see O. brevicornis Fig. 24 View FIGURES 2128 ) with 9 long, stout ventral bristles. Hind femur (see O. comosus , Fig. 31 View FIGURES 2938 ) with base entirely, dorsobasal third, slightly more than basal half anteriorly and posteriorly yellow, brown otherwise; 910 long, thin, brown, anteroventral setae present, most aligned basally in a row to brown marking anteriorly, 45 clustered at base of row; one short, brown, ventrobasal bristle present; a row of 78 short, thin to thick, bristles present posteriorly; abundant, mostly wavy, setae ventrally and posteriorly, that on apical half longest; HFWLR 1.0:4.0:1.0:4.4. Fore and middle tibiae yellow with thin, yellow bristles, longest bristle threefourths as fore or middle tibia. Hind tibia ( Fig 41 View FIGURES 3948 ). Fore tarsus with 1 yellow bristle; remaining tarsomeres of all tarsi brown.
Abdomen: Margins of most segments yellow, those on terga 14 laterally wide; sterna 14 yellow to brownyellow. Tergum 3 with 34 brown bristles in apical corner; tergum 4 with dense yellow setae laterally, bordered dorsally with several brown bristles. sternum 3 with only sparse short wavy setae medially. Sternum 4 with long, wavy, dense, yellow setae; sternum 5 bare, sternum 6 with an admedial stripe of mostly brown, erect setae, those basally yellow. Sternum 7 with 1 stout brown bristle in apical corner; sternum 8 with brown bristles apically.
Terminalia ( Figs. 139143 View FIGURES 139146 ): As O. comosus except dorsal branch wider and ventral branch without median spine. Gonostylus large, podiform.
Female. Differs from male as follows. Length, body 9.711.7 mm; wing 7.59.0 mm. Head: Face yellow tomentose, 6 thin brown bristles and thick, yellow, ventral bristles present; scape sometimes yellow; 23 brown postocular bristles present: 1.0:11.211.8. Thorax: Pronotum reddishyellow or brown. Pleuron with 07 brown katatergal bristles. Leg: Normal, without unusual setae and bristles of male. Femora brownyellow to brown on apical third to half except ventrally on fore and middle femora. Middle and hind femora with most or all ventral bristles brown; hind femur with abundant, bristly brown setae posteroventrally. Fore and middle tibiae with narrow apex light brown, bristles unusually long, thin, mostly yellow. HFWLR 1.0:5.71.0:5.8. Hind tibia normal. Fore tarsus with mostly or only brown bristles. Abdomen: Wide lateral margin of tergites 16 yellow; sternites 12 entirely or mostly yellow; margins of remaining sternites narrowly yellow. Most tergites and sternites with brown bristles apically; most sternites with 34 brown bristles laterally. Tergite 9 short, membranous, as a thin line dorsomedially.
Terminalia ( Figs. 144146 View FIGURES 139146 ): Three spermathecae present; duct basal. Sternite 8 apically triangular, sides distinctly arched, membranous medially with surface folded as a low, arched, ridge in dry specimens; apical margin rounded with a trumpetlike process anteriorly.

Distribution. A forest species captured during October to July in Cameroon and the Republic of Congo.
Etymology. Latin imaginus , for ‘likeness’ or ‘image of, referring to its similarity to O. comosus .
Remarks. Ommatius imaginus differs from O. comosus in the sparse setae on sternite 3, fringe of yellow bristles bordered dorsally with brown bristles, and the combined characters of the male terminalia ( Figs. 139143 View FIGURES 139146 ), especially the absence of an apical spine on the epandrium and the larger podiform gonostylus. Females differ from those of O. comosus in that the spermathecal duct arise directly at the base of the spermatheca ( Fig. 144 View FIGURES 139146 ) and the triangular apical margin of sternite 8 are slightly convex ( Fig. 146 View FIGURES 139146 ).
