Revision of the genus Gephyrotes Norman, 1903 (Cheilostomata, Cribrilinidae) with the description of two new taxa

The finding of a new species of Gephyrotes, G. moissettei n. sp., in Miocene deposits of southern Italy, prompted a revisionof this distinctive cribrimorph taxon, leading to the redescription and first SEM documentation of the type material of ninespecies. Five of them are retained in Gephyrotes, namely the type species, G. nitidopunctatus, and G. fortunensis, G. spectabilis,G. quadriserialis, and G. convexus, to which G. moissettei n. sp. is added. The only Recent species is the genotype,while all the others are fossils from North America, Europe and northwest Africa. Two further species are transferred tothe genus Tricephalopora, namely T. saillans and T. levigata, whereas Spiniflabellum n. gen., is established to accommodatea species from the Caribbean area, S. spinosum, previously assigned to Gephyrotes.
