Note: Reinstated by Korotkova et al. (2017), who found Strophocactus testudo (≡ Deamia testudo (Karw.) Britton & Rose, the nomenclatural type of Deamia) and S. chontalensis to form a highly-supported clade (1 PP, 98% MLBS, 99% JK), as sister to the subtribe Pachycereinae, and not closely related to the type species of Strophocactus. (Korotkova et al., 2021)
