Part of the phylogeny and relationships of Strombus species, according to Latiolais et al. (2006)[2]

In 2006, Latiolais and colleagues proposed a cladogram (a tree of descent) that attempts to show the phylogenetic relationships of 34 species within the family Strombidae. The authors analysed 31 species in the genus Strombus including Labiostrombus epidromis (referred to as Strombus epidromis in their analysis), and three species in the allied genus Lambis. The cladogram was based on DNA sequences of both nuclear histone H3 and mitochondrial cytochrome-c oxidase I (COI) protein-coding gene regions. In this proposed phylogeny, Strombus epidromis (= Labiostrombus epidromis), Strombus vittatus (= Doxander vittatus) and Strombus canarium (= Laevistrombus canarium) are closely related and appear to share a common ancestor.[2]
