The inner spines on the uropod endopod do not occur on the distal third of the margin, while the outer spines on the uropod exopod extend for its full length. The telson is cleft to one-eighth of its length, and the margins bear ten spines (including the apical spine), with the apical spine only very slightly longer than the sub-apical spine.
