H. Pilsbry and H. Lowe(1932) put in Brephodrillia the species of Iredalea with a dorsal
varix.[2] with Brephodrillia perfectus Pilsbry and Lowe, 1932 as type species. This genus is, however, considered a synonym of Iredalea Oliver, 1915 by Powell, 1966[3] In 1989 Vaught treated Brephodrillia as a subgenus of Iredalea.[4]
In 2011 Bouchet et al. treated Brephodrillia again as a synonym of Iredalea.[5]
