Monotypic. Guerrero & al. (2020) found a strongly supported clade consisting of Rimacactus sister to Neowerdermannia + Yavia.A

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.
