This spider has an overall appearance that indicates it is a close relative of members of the genus Argyrodes. However, its body shape, and especially its very long, peaked abdomen, match those illustrated for Rhomphaea species by Agnarsson. In February 2013 Platnick's World Spider Catalog included no Australian Rhomphaea species but there were some in nearby countries so undescribed species could easily exist in Australia.

The translucent, ghostly appearance of this species is probably a distinctive characteristic.

Spider(s) with a very similar appearance: Chrysso pulcherrima and Argyrodes species.
