Nadus — Hölzel 1969: 318 (Com), Stange 2004: 294 (Mon), Oswald & Penny 1991: 39 (Mon).

Type species: Nadus sudanensis Navás, 1935

Diagnosis: Medium-sized species. Fore wing slightly longer than hind wing. In wings, basal part of costal area tapering, wing tips subacute, apical margin slightly convex below tip. Anal area blunt in fore wing. Costal area of fore wing narrow with only simple cross-veins basally, then widens, cross-veins interconnected with veins or bifurcated distally. In hind wing, costal region only with simple cross-veins. Origin of radial sector well beyond cubital fork. Venation dense, legs long and slender. Tibial spurs shorter than tarsal segment 1. Abdomen shorter than wings. Caudal margin of sternite 7 slightly modified in female.

There are only three genera in the tribe Nesoleontini . Both the genera Cueta Navás, 1911 and Nesoleon Banks, 1909 are easily separated from the genus Nadus by the costal area. The costal area of Nadus is irregularly bifurcated or partially divided, whereas that of Cueta and Nesoleon is simple.

Distribution: Monotypic genus restricted to sub-Saharan Africa.
