Complete sequence analysis of the mitochondrial genome of Auriculastra duplicata (Mollusca, Gastropoda, Ellobiidae).

The mitochondrial genome of the gastropod Auriculastra duplicata was completely sequenced. It was 13,920 bp in length and comprised 37 genes; two rrn genes and 22 trn genes. Phylogenetic analyses based on the concatenated protein-coding genes depicted the polyphyly of all species belonging to the family Ellobiidae; however, monophyly was observed among all species belonging to the subfamily Ellobiinae, in which A. duplicata clustered consistently with Auriculinella bidentata.
