In July, 2017 the World Spider Catalog listed only T. argentiopunctata and T. nigronodosa as Australian Thwaitesia species. Both have variable and hence confusing markings but Thwaitesia argentiopunctata is claimed to be a North Queensland species, unlike Thwaitesia nigronodosa. Its name is based on the silvery plates that are on the top of its abdomen.

Spider(s) with a very similar appearance: Thwaitesia nigronodosa.
