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 very similar patterns of white or yellow spots on the upper surfaces of the abdomen so the presence of these is not proof that a specimen is actually Pentasteron simplex.

Spider(s) with a very similar appearance: Hetaerica scenica, Storena formosa, and Subasteron daviesae.
