Diagnostic Features
  • Apical disc raised above corona, with large, square-ended ocular plates that project strongly beyond the genital plates.
  • Periproct offset from the anterior-posterior axis; smaller than suranal plate.
  • Apical disc generally strongly ornamented with sutural pits or grooves.
  • Primary tubercles on interambulacral plates without scrobicular tubercles on adambulacral side. Tubercles imperforate and crenulate.
  • Ambulacral plating bigeminate or a mixture of bigeminate and unigeminate.
  • Peristome smaller than apical disc.

Classification and/or Status

Salenioida; Saleniidae; Saleniinae

Monophyletic

Remarks

Distinguished from other Salenioida by its squarely projecting ocular plates and its relatively broad and granular ambulacra. Salenidia (Platysalenia) Smith & Wright, 1990 is a subgenus distinguished by its rather distinctive apical disc ornament and wide and granular ambulacra.
