Simnia was named by Risso (1826) [Sepkoski's age data: T Mi-m R Sepkoski's reference number: 121]. It is extant.
It was reranked as Ovula (Simnia) by Johnson (1899).
It was assigned to Ovula by Johnson (1899); to Neotaenioglossa by Sepkoski (2002); to Ovulinae by Dolin and Lozouet (2004); and to Ovulidae by Todd (2001) and Van Dingenen et al. (2016).
