Scoliidae is a commonly found cosmopolitan family and currently one of the most neglected taxa within Hymenoptera. As expected, information on members this group scarce extremely outdated, especially when it comes to their phylogenetic relationships. The genus Scolia Fabricius, 1755 includes species that do not present diagnostic characters used identify other genera Scoliini, so can be considered "dumping ground group". Seeking better understand evolutionary history and, consequently, morphological variation in "New World" species, relationships among all from Neotropical Nearctic Regions biogeography are analysed for first time. For this, 104 proposed males females 45 species. analysis points monophyly biogeographical indicates originated Palaearctic ancestor, through dispersal event Region. Considering taxonomic obtained, aiming initially resolve part chaotic situation its subgenera, here we subgenus Discolia should restricted exclusively "Old no longer treated as Discolia, being s.s. Additionally, Hesperoscolia junior synonym Discolia. Furthermore, confirms Scoliini included it.
