Diagnosis.

Lusius is also a very distinct genus of Phaeogenini , close to Heterischnus . It can be separated from other genera in the tribe by the combination of the following characters: head hemispherical; mandible unidentate and falcate; basal flagellar segments slender and long; vertex long and slightly convex behind ocelli; occipital and hypostomal carinae joining at mandibular base; notaulus complete, ending posteriorly in a median depression; fore wing with areolet open, hind wing with distal abscissa of Cu1 absent; gastrocoelus long with thyridium faint; ovipositor extending beyond apex of metasoma; male with gonoforceps mesochorine–like, i.e. expanded into elongate process ( Tosquinet 1903, Baltazar 1964; Diller 2006).

Species richness and distribution.

The genus is represented by seven species in the Afrotropical, Neotropical and Oriental regions, with one Afrotropical species. We describe here a new species from Uganda.
