Genus Allobaccha Curran

The genus Allobaccha occurs in the Afrotropical, Indo-Malayan, Australasian and Eastern Palaearctic Regions with approximately 78 species mostly in the Oriental region. Allobaccha species are small to medium sized, with a convex facial profile (facial tubercle not very marked), usually dark thorax and abdomen with pale markings, and abdomen without margin, weakly to strongly petiolate. Some Afrotropical species of Allobaccha have an infuscate pattern on their broadened wings (Burt & Mengual 2017).
