The suggested identity of this spider is based on similarities with the appearance of other known Sidymella species and especially a species found by S. McCaffrey and L. Gibson on Barrow Island, Western Australia, and presented by PaDil at

The distinctive characteristics of this species are that it (or at least the male) lacks the triangular, arrow-shaped upper abdominal surface that is typically present on Sidymella species and this surface appears to be covered in shallow circular pits.

Spider(s) with a very similar appearance: Sidymella trapezia.
