Facing the great confusion in world literature about the genera Metacypris, Elpidium, Gomphocythere, Cytheridella, Theriosynoecum and Bisulcocypris, the authors have done a complete revision of them. This work involves the restudy of the descriptions of 212 species, the authors having examined most of the type material at several international museums, redescribing and refiguring a great part of them. The present paper promotes: a) precise diferential diagnose among those genera, their correct geographical and stratigraphical position, giving them their true systematic and stratigraphical value which had been lost due to the generalized misinterpretation of them. b) a revision and redescription of all the known species of Bisulcocypris and Theriosynoecum, as well as three new species: Bisulcocypris albertensis, sp. nov., from the Blairmore Formation, Canada; Bisulcocypris alleni, sp. nov. and Bisulcocypris martini, sp. nov., from the Wealden 4 of Germany and typical of it. c) a key to the species, a chart of their stratigraphical and geographical distribution furnishing new data for better world correlation of Mesozoic strata. d) complete and detailed bibliography up to 1961, about each species or genus studied.
