After a gap of more than twenty years, only recently the uncommon Neotropical genus Pazius Navás, 1913 has been focus of scientific researches, with the description of two new species from Colombia. Here all the knowledge about the genus is synthetized, with an identification key to all species, including comprehensive illustrations of male's terminalia and the description of Pazius angaibara sp. nov. from Northern Brazil. Also, a geographic records map of the genus is included.
