Abstract:

Schander, C., Halanych, K. M., Dahlgren, T. & Sundberg, P. (2003) Test of the monophyly of Odostomiinae and Turbonilliinae (Gastropoda, Heterobranchia, Pyramidellidae) based on 16S mtDNA sequences. — Zoologica Scripta, 32, 243−254.

While gastropod phylogeny has received much recent attention, relationships within some major gastropod clades have still not been studied. The Pyramidellidae is one such group, comprising more than 6000 named species in more than 350 genera. We sequenced part of the mitochondrial 16S gene from 32 species in an attempt to clarify pyramidellid phylogeny and employed a successive alignment approach that allowed us to maximize the phylogenetic signal of the data. Neighbour-joining, maximum parsimony and likelihood analyses recovered two distinct clades. One clade consisted of Noemiamea which nested within Odostomia (sensu stricto). The inclusion of Brachystomia, Megastomia, Jordaniella and Liostomia within Odostomia is not supported. The second clade comprised Spiralinella, Brachystomia, Boonea, Jordaniella, Liostomia and Parthenina. Our results further suggest that Turbonilla, as interpreted by most authors, is polyphyletic. This study shows that the 16S gene is useful in unravelling pyramidellid phylogeny but needs to be combined with other data (including molecular, morphological and developmental) to fully clarify the evolutionary relationships.
