Diagnosis
ReferenceDiagnosis
C. R. C. Paul and S. V. Rozhnov 2016Glyptocystitoid family with six radial plates; large periproct usually surrounded by five thecal plates, but always with plate L1 contributing to border and covered with flexible, plated integument within which simple anal pyramid located at lower right.
C. R. C. Paul et al. 2019Glyptocystitida with six or more pectinirhombs; with a cylindrical theca having six radials; a large lateral periproct surrounded by five thecal plates and covered with a flexible plated integument; five, usually short, ambulacra with 5–15 brachioles each, rarely extending into clefts in the radial plates (modified from Paul, 1984, pp. 97–8).
