The rehabilitation has yet (as of February 2016) to be recognised by the World Checklist of Selected Plant Families,[10] but is by the Missouri Botanical Gardens, with six species.

[11] The ability to resolve phylogenetic relationships based solely on morphological data is limited in the Amaryllidaceae, necessitating the use of molecular methods in addition.

Rhodophiala and Hippeastrum appeared sufficiently close to explain their treatment as a single genus in older classifications, but their separation was consistent with the study by Meerow et al.[2] The proposal to separate the two genera supports Ravenna's morphological studies, with Rhodolirium montanum (formerly Rhodophiala rhodolirion) as the type species for the new genus.

Subsequent phylogenetic analysis by Garcia et al. (2014) confirmed this distinction between the genera and proposed dividing Hipppeastrea into two subtribes, Hippeastrinae and Traubiinae, placing Rhodophiala in the first and Rhodolirium in the second.
