Taxonomic remarks and comparisons.

This species is recognised based on the descriptions and figures in Middlefart (1997) and Poutiers (1998 b), specifically in having a body whorl bearing one to two spiral ridges, in which the prominent one bears eight spines, and an elaborate crenulate outer lip with a strong incision where the spiral ridge (s) and the anal sulcus are positioned.

Murex Linnaeus, 1758
