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 nigronodosa can be found in South Queensland unlike Thwaitesia argentiopunctata, which is a North Queensland species. Its name is based on the dark spots that are typically seen on the top of its abdomen.

Known Range: Known from Cairns down to Melbourne but most common in South-east Queensland and Northern NSW.
