Taxonomy notes

the name villosa (Gray 1845) has been suggested to be the oldest name available for this species, however, the holotype is a badly damaged skull and there is a lack of compelling data to support that the name represents the same species as A. pigra and the pigra has been continuously retained in contemporary publications both to retain taxonomic stability and because of the lack of compelling evidence
