Male with inner margins of eyes strongly diverging ventrally, ocelli greatly enlarged, hind femur stouter, femoral tooth long and acute, mesoscutum mostly coriaceous with punctures along notaulus, and area superomedia more slender. Differential diagnosis Moderately small and mostly black; differentiated from all other Afrotropical species by the very short and entirely straight ovipositor. Also characterized by the very short malar line, the coriaceous scutellum and the entirely punctate speculum.
