Zethus Fabricius, 1804 is the largest genus in the subfamily Eumeninae with over 250 species. Its Neotropical representatives are divided into three subgenera: Z. (Zethus) Fabricius, 1804; Z. (Zethusculus) de Saussure, 1855; and Z. (Zethoides) Fox, 1899. Two specimens were collected in the northeastern region of São Paulo state, Brazil belonging to two species of the latter subgenus: Z. (Zethoides) lobulatus de Saussure, 1855 and Z. (Zethoides) rugosiceps Fox, 1899. These species have so far only been collected in the Amazon Forest and these findings not only expand the latitude of the species’ distribution but also their occurrence to the Atlantic Forest as well.
