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 http://www.padil.gov.au.

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.
