Figs 10, 12, 14, 16.

Diagnosis

By external characters Afroarabiella sulaki sp. nov. can be confused with A. tahamae , but differs from it by the following features: the grey costal margin of the fore wing, the longer transtilla process, the long needle-like cornutus and the phallus smoothly curved in its basal third.

Etymology

The new species is named after the German lepidopterist Harald Sulak (Munich).
