Journal Article
Published: 07 March 2017
Journal of Paleontology (2017) 91 (4): 755–766.
... The systematics of Holocystitidae has been continuously revised and subdivided according to inferred differences in thecal and oral area morphology but in the absence of a unifying plating model of the oral area. Although two circlets of plates around the peristome were recognized (periorals, herein interpreted...

... diplopores, humatipores (restricted to taxa within the Holocystitidae), in which a pore pair is connected with multiple canals, that are buried just under the surface of the thecal plate (Paul, 1971 ; Frest et al., 2011 ; Sheffield and Sumrall, 2017 ). There have been reports of ‘unbranched’ diplopores...

... family Holocystitidae ( Paulicystis Frest and Strimple, 2011 in Frest et al., 2011 ) and in paracrinoids ( Malocystites Billings, 1858 ). Rhombiferans, diploporites, and paracrinoids differ by so many other characters that recumbent ambulacra are likely to have evolved independently in each. Bockelie...

... the arrangement of plates in the oral area was not previously understood, but also because genera that are now included in the family Holocystitidae were previously included within the Aristocystitidae. All aristocystitid genera in which the oral plating and ambulacra are known have a mouth elongated...

The monophyletic grouping uncovered in Sheffield and Sumrall ( 2019a ), Sphaeronitida (which also includes the monophyletic grouping Holocystitidae), is present in the fully bifurcating tree, though relationships within sphaeronitids have changed (e.g., Holocystites salmoensis is the sister taxon to other...

S250), largely because the arrangement of plates in the oral area was not previously fully appreciated, but also because genera that would now be included in the family Holocystitidae were previously included within the Aristocystitidae.
