We revise the exclusively Neotropical solenopsidine ant genus Oxyepoecus, starting here with the Vezenyii species-group. We describe five new species (O. browni, O. ephippiatus, O. longicephalus, O. kempfi, and O. quadratus), present new locality records and sum the few data on the biology of the species already described.
