Bivalvia - Pectinida - Pectinidae

Taxonomy
Mimachlamys was named by Iredale (1929) [Sepkoski's age data: T Eo-m-l R Sepkoski's reference number: 1112]. It is extant.

It was reranked as Chlamys (Mimachlamys) by Shuto (1971).

It was assigned to Chlamys by Shuto (1971); to Pectinidae by Lamprell and Whitehead (1992); to Chlamydinae by Todd (2001); to Pterioida by Sepkoski (2002); and to Mimachlamydini by Bouchet et al. (2010).
