Phylogeny
| |||||||||||||||||||||||||||||||||||||||||||||
| Phylogeny and relationships of Strombidae according to Simone (2005)[3] |
The phylogenetic relationships among the Stromboidea have been accessed in 2005, by Simone. He proposed a cladogram (a tree of descent) based on an extensive morpho-anatomical analysis of representatives of Aporrhaidae, Strombidae, Xenophoridae and Struthiolariidae.[3]
In his analysis, Simone recognized Strombidae as a monophyletic taxon supported by 13 synapomorphies (traits that are shared by two or more taxa and their most recent common ancestor), with at least eight distinct genera. He considered the genus Terebellum as the most basal taxon, distinguished from the remaining strombids by 13 synapomorphies, including a rounded foot.[3] Though the genus Tibia was left out of the analysis, Simone regarded it as probably closely related to Terebellum, apparently due to some well known morphological similarities between them.[3]
