A preliminary cladistic analysis of North Atlantic Oenopota Moerch, 1852 and Propebela Iredale, 1918 (Gastropoda: Conoidea)

Abstract

The phylogeny of 23 species of the conoidean gastropods Oenopota and Propebela from the North Atlantic is estimated in a parsimony analysis based on 26 morphological characters. Mangelia attenuata (Montagu, 1803) is used as outgroup. The results indicate that most Propebela species form a monophyletic group within the Oenopota/Propebela complex, whereas Oenopota constitutes a paraphyletic assembly. The genus Curtitoma Bartsch, 1941 is probably non-monophyletic.
