Two new taxa of Aegialiini (Coleoptera: Scarabaeidae: Aphodiinae) are described from South America: Argeremazus neuquen Stebnicka and Dellacasa, n. gen, n. sp, and Amerisaprus valdivia Stebnicka and Skelley, n. gen, n. sp. Both genera are presently monotypic. Discussion on the generic status of Caelius Lewis is presented. A key to genera and checklist of aegialiine taxa occurring in the New World are presented.
