Revision of the regular echinoid genus Glyphopneustes Pomel, 1869 and establishment of Aliopsis gen. nov. from the Maastrichtian of the United Arab Emirates/Oman border region

Description
Summary:The genus Glyphopneustes Pomel, 1869 is revised because a comparison of the morphological features of the type species, G. problematicus (Cotteau, 1866), and those of Glyphopneustes hattaensis Ali, 1992, had revealed the presence of significant differences. Based on these, a new genus, Aliopsis, is here erected, with G. hattaensis as its type species. The new genus is described systematically and attributed to the family Acropeltidae Lambert and Thiéry, 1914 in the order Arbacioida Gregory, 1900.
