Male. As O. comosus except as follows. Length, body 12.1 mm; wing 7.8­7.9. Head: FHWR 1.0:7.8­1.0:7.9. Frons yellow to yellowish­gray tomentose.
Thorax: katatergal bristles entirely yellow to mostly brown.
Wing (Fig.19).
Leg: Fore femur (see brevicornis, Fig. 23) with ventral row of 8­9 unusually long, thick, yellow bristles. Hind femur (see comosus, Figs. 31). HFWLR 1.0:4.1­1.0:4.8. Hind tibia (Fig. 46).
Abdomen: Tergite 4 laterally with dense fringe of thin, mostly yellow bristles, brown bristles borders fringe dorsally. Sternite 3 with only sparse, short wavy setae.
Terminalia (Figs. 197­201): Ventral lamella bare, row of dense red­orange setae absent. Epandrium 3 branched; dorsal branch narrow; not forked apically; median branch minute; ventral branch apically wide, notch and claw­like bristles present. gonocoxite with minute setae in large sockets. Hypandrium without tuft of apical bristles.
Female. Differs from male as follows. Length, body 10.3­13.8 mm; wing 8.0­ 9.5 mm. Body darker than male. Head: Face with thick dark bristles ventrally; FHWR 1.0:10.0­ 1.0:10.5. Thorax: Pleuron with meron entirely and anepimeron mostly black. Leg: Femora and tibiae normal, without unusual vestiture and shapes. Fore and middle femora brown on apical third, dorsal two­thirds brown on hind femur. Middle and hind femora usually with brown ventral bristles; HFWLR 1.0:6.0­1.0:6.2. Tarsi with only brown bristles. Abdomen: Without unusual vestiture of tergite 5 and sternites 4­6. Tergites 1­5 or 6 with wide, lateral margins yellow. Tergite 9 longer than cercus, mostly membranous, sides narrowly sclerotized. Sternites 3­7 with brown bristles apically and laterally. Terminalia (Figs. 202­204): Three spermathecae present; duct basal. Sternite 8 strongly triangular apically, sides diagonal, membranous oval area medially, extends anteriorly as a low, arched carina in dry specimens; carina membranous when treated in KOH, trumpet­shaped; several stout bristles present in apical corner.

Gradham / in bush (BMNH); 1 ♀, Nigeria: / Lagos / G. Strachan (BMNH). REPUBLIC OF CENTRAL AFRICA: 1 ♀, La Maboke / 25.viii.1970 / L. Matile (MNHN); 1 ♀, same data except 1.x.1970 (MNHN).
Distribution. The species was captured during April through November in Cameroon and the Republic of Central Africa.
Etymology: Latin, renudus, “bare”, referring to the absence of long dense setae on the ventral lamella.
Remarks. The characters in the key and comments in the remarks section of O. comosus separate O. renudus from congeners.
