Acrilla was named by Adams and Adams (1860) [Sepkoski's age data: K Camp-l R]. It is extant.
It was reranked as Scala (Acrilla) by Dall (1889); it was reranked as Scalaria (Acrilla) by Tate (1893); it was reranked as Epitonium (Acrilla) by Maury (1925) and Rivera (1957); it was reranked as Amaea (Acrilla) by Abbass (1967).
It was assigned to Scala by Dall (1889); to Scalaria by Tate (1893); to Epitonium by Maury (1925) and Rivera (1957); to Amaea by Abbass (1967); to Epitoniidae by Durham (1937), Turner (1938), Durham (1944), Harris and Palmer (1947), Dockery (1977), Zinsmeister (1983), Squires and Demetrion (1992) and Wilson (1993); and to Neotaenioglossa by Sepkoski (2002).
