Molecular phylogeny and revised classification of the Buccinoidea (Neogastropoda)

Abstract The superfamily Buccinoidea is distributed across the oceans of world from Arctic Ocean to Antarctic and intertidal abyssal depths. It encompasses 3351 recent species in 337 genera. latest taxonomic account recognized eight full families. For first time, monophyly relationships among families are tested with molecular data supplemented by anatomical radula data. Five genetic markers were used: fragments mitochondrial COI, 16S rRNA, 12S rRNA nuclear Histone 3 (H3) 28S genes (for 225 117 genera). Our analysis recovered monophyletic Bayesian analyses. between formerly subfamilies drastically revised a new classification here proposed, now including 20 taxa family rank 23 subfamilies. (Chauvetiidae, Dolicholatiridae, Eosiphonidae, Prodotiidae Retimohniidae) one subfamily Nassariidae (Tomliniinae) described. Austrosiphonidae Tudiclidae resurrected synonymy employed taxonomical extension. All but 40 genera reclassified. results demonstrate that anatomy rather uniform within superfamily. With exceptions, radular morphology alone does not allow allocation particular without additional
