The mitogenome of the sunken wood limpet<i>Notocrater youngi</i>: insights into mitogenome evolution in Lepetellida (Gastropoda: Vetigastropoda)

ABSTRACT The complete mitochondrial genome of the pseudococculinid limpet Notocrater youngi was determined using Illumina sequencing and found to be a double-stranded circular molecule 15,915 bp in length. It contains usual 13 protein-coding genes, 2 ribosomal RNA genes 22 transfer although with gene order that differs from those all other presently known Vetigastropoda, is derived within Lepetellida. Phylogenetic analyses based on amino acid sequences join three species clade confirm well-supported Scissurelloidea + (Lepetelloidea Lepetodriloidea) but not monophyletic Lepetellida as currently understood. Patterns rearrangements are concordant these findings.
