 Some confusion exists between this species and "M. insignis".For example, H. Womersley in 1943 regarded "Actinopus formosus" as a synonym of "M. occatoria", whereas Barbara York Main in 1985 treated it as a synonym of "M. insignis", the position adopted by the World Spider Catalog.She considered that Womersley had partly confused "M. occatoria" and "M. insignis", with "M. occatoria" only occurring in eastern Australia.
