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.


Phylogenetics: The genus contains only three species; two of them (A. ritteri and A. hintonii Glass & W. A. Fitz Maur.) have been found well supported as sisters to each other (Vázquez-Sánchez & al. 2013).A
