摘要

The idea of a sister-group relationship between the cephalopod superorders Decabrachia (squids and cuttlefishes) and Vampyropoda (octopods, cirroctopods and vampire squid) has been widely accepted since Jeletzky (1966: fig. 2). In their phylogenetic analyses, Berthold & Engeser (1987) and Engeser & Bandel (1988) regarded the presence of suckers as a character state that supports the monophyly of what they called the ‘sucker-bearing Coleoidea’. In 1997, Haas introduced the terms ‘Neocoleoidea’ for coleoid groups with living representatives and ‘Palaeocoleoidea’ for a group of hook-bearing coleoids also known as ‘Belemnoidea’, which was thought to have disappeared at the end of the Cretaceous.
