Abstract
Zethus giseleae new species is described from Maranhão State, Northeastern Brazil. The species fits into the Z. hilarianus species-group which was partially revised only recently, and a set of features from both external morphology and male genitalia allows readily separation from closely related taxa. Notes on morphology and collecting records of Z. alessandroi are also provided, extending its range within the Southeast Amazon domain.
