The Echinoid Directory

• Apical disc relatively flat and raised above the corona, with smooth, unornamented plates and weak to strong sutural pits.
• Periproct offset to posterior right from anterior-posterior axis; generally a little smaller than the suranal plate.
• Gonopore opening subcentral on genital plate and clearly visible in aboral view.
• Ambulacral plating entirely unigeminate; zone of granulation developed between the two columns of primary tubercles.
• Primary tubercles imperforate and crenulate; no scrobicular tubercles on adradial side.
• Peristome with weak buccal notches.

Salenioida; Saleniidae; Saleniinae.

Presumed monophyletic.

Species in this taxon have entirely unigeminate ambulacral plating, which distinguishes it from its immediate sister-group Salenia. Pleurosalenia differs from Salenocidaris in having smooth, unornamented apical disc plates.
