Chariergus White, 1855 is interpreted based on C. tabidus (Klug, 1825) (type species designated by Thomson, 1864). Allopeba gen.n. is proposed for A. paranaensis (Napp & Reynaud, 1998) comb.n. (type species), A. signaticornis (Lucas, 1857) comb.n. and A. quadri-punctata (Lucas, 1857) comb.n. Rierguscha Viana, 1970 and its species are redescri-bed. The morphology of Chariergus tabidus (Klug, 1825) and Allopeba signaticornis (Lucas, 1857), including the mouth pieces, endostemites, wing venation and male and female terminalia, is presented. Key for the genera and species is added.
