The question mark after the species name shown on this page has been placed there because some arachnologists believe the abdominal markings visible on this spider are those of the Asian species Nihonhimea mundula. However, as of March 2019 the World Spider Catalog does not list Nihonhimea mundula as being in Australia and still recognizes Parasteatoda decorata as being a Queensland species. Hopefully, this uncertainty will be resolved in the near future.

Spider(s) with a very similar appearance: Latrodectus hasseltii.
