Notes
Revisions/monographs by Heil & Porter (1994) and Hochstätter (2005). Confirmed as monophyletic by Butterworth & al. (2002) and Vázquez-Sánchez & al. (2013). The generic status and limits of Echinomastus need further evaluation because it was found polyphyletic by Vázquez-Sánchez & al. (2013).A,B,C,D,E
Taxon standing
Category B. The genus is monophyletic based on phylogenetic studies that support the clade based on a sufficiently dense or even complete sampling, or support a monotypic genus as a distinct lineage, but do not provide a new taxonomic treatment at the species level. In many cases, older classical taxonomic synopses or a monographic treatment exist for these genera providing a reliable assessment of the species included.
