Taxonomic remark The family and superfamily placement of this genus within SubOrder Terebratellidina was uncertain for a long time (per BrachNet 2023), but Simon Mottequin (2018) recognized the similarity of Simplicithyris to the fossil genera Jagtithyris and Leptothyrellopsis, and therefore tentatively assigned it to the same family (Jagtithyrididae). However, given the great stratigraphic gap between the extant Simplicithyris and these Cretaceous genera, it may prove better to create a new family/sub-family in future. [details]
