Two new genera of flea beetles are described and illustrated: Brasilplatus Oliveira, Linzmeier Konstantinov new genus, monotypic, type species B. bahianus Oliveira, Linzmeier Konstantinov new species, and Tupiniquim Linzmeier, Oliveira Konstantinov new genus, containing two species, T. pronotalis Linzmeier, Oliveira Konstantinov new species and T. confusa Linzmeier, Oliveira Konstantinov new species and type species of the genus. These are the first described genera of flea beetles inhabiting leaf litter in Brazil. Brasilplatus belongs to the subtribe Monoplatina and is compared to other Monoplatina genera known to occur in leaf litter or moss cushions: Andersonaltica Linzmeier Konstantinov, 2012, Apleuraltica Bechyn, 1956 and Ulrica Scherer, 1962. Tupiniquim is unique among New World flea beetles, it allies cannot be immediately identified. Here it is compared to several New World and Old World genera.
