The complete mitogenome of and the basal phylogeny of Helicinae (Gastropoda, Stylommatophora, Helicidae).

A complete mitochondrial genome of the Roman snail Linnaeus, 1758 has been sequenced. The length and gene order correspond to that of other available helicid mitogenomes. We used the mitogenome sequence to reappraise the relationships among the four presumed principal groups of the helicid subfamily Helicinae.
