Eromangateuthis n. gen., a new genus for a late Albian gladius-bearing giant octobrachian (Cephalopoda: Coleoidea)

Abstract

A comparative analysis shows that the gladius morphology of Boreopeltis helgolandiae Engeser & Reitner, 1985 (Aptian), the type species of Boreopeltis Engeser & Reitner, 1985, Boreopeltis sagittata (Naef, 1921) (Tithonian), and Boreopeltis smithi Fuchs & Larson, 2011 (Cenomanian) is fundamentally different from Boreopeltis soniae Wade, 1993 (Aptian). I therefore propose Eromangateuthis n. gen. in order to accommodate Eromangateuthis soniae (Wade, 1993).
