DISTRIBUTION:

Orthogonioptilum subueleense (wingspan: males: 56-65mm; females: larger) flies in
southwestern Republic of Central Africa: La Maboke, probably east to southern Ouaka;
northern Congo;
northern Gabon: Estuaire, Woleu-Ntem and Ogooue-Ivindo, near Belinga; and
central and eastern Cameroon: Adamaoua, West, Sud, Est, la Sanaga, du Nyong, Dja, de la Sangha.

The forewing is quite falcate and is very drawn out. The hindwing outer margin is a little less convex than in O. ueleense and O. bergeri (on the same wing, the postmedian line is a little closer to the outer margin than in the other two species). The ground colour is a clear, beigey-brick, sometimes a little more reddish, but generally brighter than allied species. Orthogonioptilum subueleense male, All Leps Barcode of Life.

The dark patches along the costa are usually well marked (sometimes almost absent). The transverse line can be clear or barely present. The pm line is fine on both wings; the am line is absent or very weak. There is a single tiny "point of light" on each wing, sometimes accompanied by one or two other fine points.

The pronunciation of scientific names is troublesome for many. The "suggestion" at the top of the page is merely a suggestion.

There are many collectors from different countries whose intonations and accents would be different.

The genus name Orthogonioptilum refers to the nearly right angle at the anal angle of the forewing.

The species name is named for its similarity to O. ueleense, a more easterly species, encountered in Uele, Zaire.
