Face sparse setose, setae mostly short, longer ventrally; 6 thin, brown and 4 pencillike yellow bristles present; FHWR 1.0:10.01.0:10.5. Proboscis with narrow base yellow. Antenna brownishyellow, flagellum darkest. Frons brownyellow tomentose, brown setose. Ocellar tubercle with longest seta as long as pedicel and scape combined. Occiput with 56 brown postocular bristles, longest bristle about half distance toward ocellar tubercle.
Thorax: Mesonotum largely dark brown, corners yellow laterally, yellowishbrown dorsally; tomentum mostly brown, yellowishbrown to yellow laterally and posteriorly; narrow paramedial stripe boarded by thin, yellowishbrown tomentum; setae sparse, mostly brown, 4 lateral and 2 dorsocentral brown bristles present.

Tergites 17 usually with narrow lateral margin yellow; tergites 58 with an apical row of bristly setae, at least 1 in apical corner of tergite 4. Sternites with mostly yellow vestiture; sternites 57 apically with several bristly, brown setae, and laterally with 23 bristles. Tergite 9 membranous dorsally, extremely short. Terminalia ( Figs. 194196 View FIGURES 189196 ): Three spermathecae present; duct basal. Sternite 8 with apex acutely triangular, with medioapical ridge that apically forms a small hooked spine; surface thin, membranous; several long, thick, brown bristles present.

Distribution. A forest edge species captured throughout the year in West Africa.
Etymology. Latin, porticus , for ‘gallery or path’ [forêt galerie] in a forest.
Remarks. In addition to the characters in the key, the male O. porticus is recognized by the combined characters of the terminalia ( Figs. 189193 View FIGURES 189196 ) and the two rows of erect setae on sternites 46.
