F . Hind tibia, lateral view. Differential diagnosis Moderately small, black and testaceous species from Réunion Island ; differentiated from all other Afrotropical species by the combination of the black orbits, the partially testaceous mesoscutum, the entirely punctate speculum, the stout area superomedia in the female and the strong female femoral tooth.
