Diagnosis Solitary, discoidal, free. Costosepta compact, exsert, finely granulated laterally. Pali opposite all cycles of septa, merging with papillose columella. Wall septothecal. [details]Remark In the past, a few Cretaceous forms were originally assigned to Leptocyathus. The forms known to the author are Leptocyathus gracilis Duncan, 1870, from the Lower Cretaceous to the Lowermost Upper Cretaceous of England, and Leptocyathus hexacristatus Alloiteau, 1936, from the Maastrichtian of Madagascar. Because, based on e.g. the appaerance of both very elongate paliform structures before all septal cycles and very smooth septal margins, Duncan's material seems to rather correspond to the genus Deltocyathus. In addition, recent studies carried out on the type material of Leptocyathus hexacristatus Alloiteau by Baron-Szabo (2008, p. 160) revealed that it corresponded to the taxon Paracycloseris nariensis (Duncan, 1880). Therefore, the occurrence of the genus Leptocyathus is most likely restricted to the Cenozoic. [details] Unreviewed
