Notes

Phylogenetics: Strophocactus was originally established as a monotypic genus by Britton & Rose (1913) and remained in this circumscription until (Hunt 1989) transferred Strophocactus to Selenicereus. The reinstatement of Strophocactus with three species previously placed in Selenicereus was suggested by Bauer (2003) and adapted by Hunt (2006). Korotkova & al. (2017), based on plastid trnK/matK, rpl16 intron and trnL-F, found Strophocactus sensu Bauer (2003) as polyphyletic; its nomenclatural type S. wittii was found nested within Pseudoacanthocereus, as sister to P. sicariguensis while Strophocactus (=Deamia) testudo and S. chontalensis formed a highly-supported sister to the subtribe Pachycereinae. Based on these results, Korotkova & al. (2017) newly circumscribed Strophocactus to include Pseudoacanthocereus and reinstated Deamia.A
