Stenomesseae was a tribe (in the family Amaryllidaceae, subfamily Amaryllidoideae), where it forms part of the Andean clade, one of two American clades. The tribe was originally described by Traub in his monograph on the Amaryllidaceae in 1963, as Stenomessae based on the type genus Stenomesson. In 1995 it was recognised that Eustephieae was a distinct group separate from the other Stenomesseae. Subsequently, the Müller-Doblies' (1996) divided tribe Eustephieae into two subtribes, Stenomessinae and Eustephiinae.
The advent of molecular phylogenetics showed that the Stemomesseae (including Stenomesson) was polyphyletic. Consequently, a separate tribe (Clinantheae) was created from one group and the remainder, which segregated with Eucharideae was treated as another tribe. Initially it was suggested that this combined tribe be referred to as a newly circumscribed Stenomesseae, but subsequently the term Eucharideae has been conserved.
The placement of Stenomesseae, now Eucharideae within subfamily Amaryllidoideae is shown in the following cladogram.

Eustephieae is a tribe (in the family Amaryllidaceae, subfamily Amaryllidoideae), where it forms part of the Andean clade, one of two American clades. This tribe was resurrected from the Stenomesseae in 1995, by Meerow. The placement of Eustephieae within subfamily Amaryllidoideae is shown in the following cladogram, where this tribe is shown as a sister group to the remainder of the tetraploid Andean clade. Four genera: Eustephia Chlidanthus Hieronymiella Pyrolirion The Eustephieae for the southern limit of the Andean clade.
Eucharideae is a tribe of plants within the family Amaryllidaceae. It was augmented in 2000 by Meerow et al. following a molecular phylogenetic study that revealed that many elements of the tribe Stenomesseae segregated with it, rather than separately, and were subsequently submerged in it (although there was an initial proposal to rename this clade Stenomesseae). Further revisions were made in 2020, when three genera were merged. It forms one of the tribes of the Andean subclade of the American clade of the subfamily.
Clinantheae is a tribe (in the family Amaryllidaceae, subfamily Amaryllidoideae), where it forms part of the Andean clade, one of two American clades. The tribe was described in 2000 by Alan Meerow et al. as a result of a molecular phylogenetic study of the American Amaryllidoideae. This demonstrated that the tribe Stenomesseae, including the type genus Stenomesson was polyphyletic. Part of the tribe segregated with the Eucharideae and were submerged into it, while the other part formed a unique subclade.
