Phylogenetics: Monotypic genus from eastern Brazil. Sampled by Schlumpberger & Renner (2012) and found highly supported as sister to Facheiroa ulei. Both genera used to be included in the Trichocereeae, but their exact affinities were unclear (Taylor & Zappi 2004). Schlumpberger & Renner (2012) found Leocereus and Facheiroa outside the Trichocereeae and within a clade containing Stetsonia, Cereus, Praecereus, Micranthocereus, and other genera.

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.
