Complete mitochondrial genome of <i>Laeocathaica amdoana</i> Möllendorff, 1899 and phylogenetic analysis of Camaenidae (Gastropoda: Stylommatophora: Helicoidea)

The first complete mitochondrial genome of the dart sac-bearing camaenid <i>Laeocathaica</i> Möllendorff, 1899 was sequenced and analyzed in this study. The whole mitogenome of <i>Laeocathaica amdoana</i> Möllendorff, 1899 was 14,660 bp in length and its nucleotide composition showed high AT-content of 67.45%. It had 37 genes, including 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The phylogeny yielded by both Bayesian inference and maximum-likelihood method suggested that <i>Laeocathaica</i> was closely related to the other dart sac-bearing camaenids with known complete mitochondrial genome. These genetic data are expected to provide fundamental resources for further genetic studies on the camaenids.
