Phylogenetic analysis of most genera within fossil and extant Raninoida (Brachyura) based on 72 adult morphological characters yielded a new superfamily and family level classification for the section. The section was most diverse at the family level during the Late Cretaceous but remains diverse at the genus and species level in the Holocene. New subfamilies include Bicornisranininae, Macroacaeninae, and Rogueinae within Lyreididae. New genera include Colombicarcinus, Alessandranina, Claudioranina, Giulianolyreidus and Italianira, and one new species, Colombicarcinus laevis, is described. New combinations include Alessandranina ornata (Wright and Collins, 1972), Claudioranina oblonga (Beschin, Busulini, De Angeli, and Tessier, 1988), Heus manningi (Bishop and Williams, 2000), Italianira punctulata (Beschin, Busulini, De Angeli, and Tessier, 1988), Giulianolyreidus bidentatus (Rathbun, 1935a), G. johnsoni (Rathbun, 1935a), Lyreidus teodorii (van Bakel et al., 2012), Macroacaena tridens (Roberts, 1962), M. teshimai (Fujiyama and Takeda, 1980), M. yanini (Ilyin and Alekseev, 1998) and Quasilaeviranina eocenica (Rathbun, 1935a).
