May be confused with

Cyphanthidium may resemble Afranthidium in their size and in having continuous colored bands on the abdomen. Cyphanthidium can be distinguished from Afranthidium by the presence of an arolia and the four-toothed mandibles of the females. Cyphanthidium and Afranthidium are sympatric in South Africa; however, Afranthidium has a broader distribution that extends to southern Europe and western Asia (Michener 2007).
