The same species?

Distinguishing features of this spider are its shiny black body, colourless leg segments and yellow abdominal spots. It should be noted that many other zodariid species have somewhat similar patterns of white or yellow spots on the upper surfaces of the abdomen so these spots should not be used as the sole identifying feature for Pentasteron simplex.

Spider(s) with a very similar appearance: Many other Australian zodariid species.
