Ablerus is the only genus in the family Azotidae (in Superfamily Chalcidoidea). The genus was created by the American entomologist Leland Ossian Howard in 1894 for the species named in that year by William Harris Ashmead as Centrodora clisiocampae. The genus Azotus was synonymized with Ablerus by Alexandre Arsène Girault in 1913 and Hayat synonymized Myocnemella with Ablerus in 1994, leaving Ablerus as the sole genus within the subfamily Azotinae (in family Aphelinidae).
