Pucara leucantha is transferred to Stenomesson as Stenomesson leucanthum based on the phylogenetic position of Pucara resolved by nuclear and plastid DNA sequences. An allied species, Stenomesson chloranthum , is described from the Departments of Amazonas and Cajamarca in Peru, but at lower elevations. Both of these species release their pollen in tetrads, unique within Amaryllidaceae, and have tri-lobed stigmas, unique within Stenomesson.
