A new classification of the subgenus Zaprionus is proposed in light of recent phylogenetic findings. The boundaries of the armatus and inermis species groups are redefined. The vittiger subgroup is upgraded to the level of a species group. The tuberculatus subgroup is transferred from the armatus to the inermis group. A new monotypic group, neglectus, is erected. Full morphological descriptions of four species belonging to the vittiger group are given: Zaprionus lachaisei sp. n. from Tanzania and Zaprionus santomensis sp. n. from São Tomé and Principé, and two cryptic species of the indianus complex, Zaprionus africanus Yassin & David and Zaprionus gabonicus Yassin & David. Three nominal species are synonymised: Zaprionus beninensis Chassagnard & Tsacas, syn. n. with Zaprionus koroleu Burla, Zaprionus simplex Chassagnard & McEvey, syn. n. with Zaprionus neglectus Collart, and Zaprionus megalorchis Chassagnard & Tsacas, syn. n. with Zaprionus ornatus Séguy. Half of the 46 species of the subgenus are available as laboratory strains and this has allowed full descriptions of the internal structure of their reproductive systems and their immature stages.
